Who uses emojis?

Emojis are not for everyone, you need to fully understand your target audience before you start including emojis in your content. According to Sproat Social, 60% of women use emojis frequently compared to 41% of men. They also reported that 75% of men and 84% of women respondents believe emojis are a better way to express their emotions than words.

Emogi have broken emoji users down into three groups light, medium and heavy users.  “Heavy” mobile users are female, younger, and highly engaged with emojis. Over 50% of their messages will include a emoji and they would like to see more alternative emojis beyond the standard set. As we can see from this graph its not just millennials using emojis. Gen X and baby boomers are using emojis more and more as a form of communication.

Social media Twitter

Including emojis in Tweets is shown to increase engagement by 25.4%. Larry Kim did a simple split test to see which paid ad performed best, (with or without emoji). The one with an emoji received a higher engagement rate. Consider doing this test for yourself to see how your audience responds before using emojis regularly in your content.

Even if emojis do increase your performance that doesn’t mean you will get it right. Take Sports Centre for example. They attempted using all emoji tweets to represent the length of the game because of the high-number of replays. This was highly misunderstood by their followers.

Goldman Sachs shared a tweet in March 2024 that looked at the spending habits of millennials. They condensed their findings into a series of emojis. People criticized the businesses for the message being unprofessional and misunderstood.

We might not always get it right, and sometimes it will require some trial and error. Test out tweets including emojis and evaluate the response.

Facebook

The most popular emoji used on Facebook last year that received the highest engagement was?. Consider the context for you featuring an emoji, and don’t sprinkle them in every update. Use them in the right context and stick to one or two.

Instagram

Over 50% of Instagram captions now feature an emoji, its hard sometimes to find a caption not featuring an emoji. This will be due to over 50% of Instagram users being millennials. This Instagram emoji study shows that faces account for 6 of the top 10 emoji hashtags. Unsurprisingly, the hearts and hand gestures round out the top 10.

Instagram’s use of emojis is focused on communicating a mood or feeling to their followers. Of the 20,000 Instagram profiles examined by Quintly, 56% used emojis during 2024. According to AdWeek marketers are using emojis to appear more friendly and to tell stories in their marketing campaigns, tapping into the language their followers and fans use. AdWeek believes emojis are a necessity on Instagram.

Of the 2,000 existing emojis the most popular emoji was used nearly 50,000 times. If you plan to include new emojis in your posts it might improve the interactions you receive on videos and images.

Advertising

Over the past few years, we have seen more emojis used by marketers in their campaigns. Marketers need to evolve with their customers, they need to use new technologies such as emojis if they want to truly understand and emotionally connect with their target audience.

Using emojis can help improve communication with your audience and keep a playful company tone of voice across your platforms. It has been found that emojis trigger the emotional parts of our brains, almost the same way as seeing a smiling face tends to trigger a reaction in our own feelings. Therefore using emojis can have a positive impact on your marketing efforts.

We have seen some brands taking emojis to another level and creating their own. Marketers are now harnessing emoji and creating an integrated experience around them. Brands like Loreal, Star Wars, Ikea and celebrities like Kim Kardashian have built their own emoji keyboards for fans to use on messenger, text and on social media.

If you plan on using emojis consider how they will engage your target audience first and if they will tell the right story. Future emoji marketing campaigns that will generate buzz will be the ones that communicate effectively and are authentic in their emoji usage.

Email

Most of us expect to see emojis on social media on or in messenger but when it comes to email some of us haven’t made the connection. A recent study compared the open rate of a subject line with an emoji and without a emoji. The animated subject line increased the unique open rate after 70 hours by over 20%. Experian have also reported that subject lines with symbols had a higher unique open rate of 56 percent.

MailChimp did an interesting study looking at the trends and usage of emojis in subject lines. They found the top 15 emojis used in emails and found that 31% of campaigns with emojis use more than one of them.

MailChimp recommends using emojis to convey meaning rather than as a gimmick. As screen sizes get smaller, senders need to find ways of including more information and emotion into shorter messages. Emojis are great for this.

Seasonal emojis are a great way to start using emojis and to visually boost your seasonal content. Consider using Christmas, Halloween or Easter to push your content and have fun with your emails.

Therefore, by using emojis or animations in your subject line, you can help you stand out in your subscriber’s fully loaded inbox. If your email marketing campaigns can communicate effectively through emojis and are authentic in their emoji usage, they may help re-engage your lost subscribers.

For now, emoji marketing is still generating buzz and you can find them everywhere on social media, television, and in print. But there are a few questions you should ask yourself before including them in your campaigns and content.

Do you know the meaning behind the emoji?

Make sure you are using emojis in the right context and understand the different meanings of emojis. Using emojis can put your brand’s reputation at risk and can communicate a totally different message to what you initially planned. Here is a funny, but an unfortunate example.

Is it the appropriate time and place?

Are they relevant?

The biggest risk in using emojis, is your message getting lost in translation. Consider your audience first before including emojis. Don’t just stick an emoji in a tweet for the sake of it. Check the meaning, then consider if it’s relevant. If you want to ease your way into using emojis start with seasonal emojis or look at trending topics or national holidays to make your posts relevant.

Have you tested emojis in your marketing campaigns? Which marketing channel do you plan to target for testing emojis? If you want to see more examples of how brands have emotionally connected with their target audience using emojis check out these 5 examples.

The Anatomy Of A Great Multicultural Marketing Campaign

Understanding the specifics of the lifestyles, habits, preferences, and needs of people of various cultural backgrounds can be the key to rapid campaign success

If you really want to engage your customers, then you should know what it is like to be in their shoes. Understanding the specifics of the lifestyles, habits, preferences, and needs of people of various cultural backgrounds can be the key to rapid campaign success.

If you have already dabbled in international marketing, the following is nice to keep in mind: your customers are people who come from different countries, with different goals, purposes and daily challenges. They may not have equal access to the internet and particular web sources where you could communicate with them. Understanding this should be the first step towards growing a robust, diversified marketing campaign.

This guide is designed to enable you to review and refresh their existing approach to campaign planning in order to develop a more structured process which integrates the latest digital marketing techniques better.

Multicultural marketing campaign strategy includes targeting people of different cultural backgrounds individually but with the brand’s same overarching touch. It’s all about meeting the needs of specific target audience segments instead of delivering an impersonal message designed for both everyone and no one in particular.

We’ve compiled some of the most effective tactics that could help you to implement multinational marketing campaigns. But first, let’s consider why it is so important.

How different ethnicities consume content

The Asian American population grew by at least 72% between 2000 and 2024, as reported by Pew Research, which made this ethnic group the fastest growing in the US. As predicted by the US Census Bureau, by 2060, the Hispanic population will have grown by 115% and by that time will make up 29% of the total US demographic.

If you’re not doing multicultural marketing yet, then you’re not doing marketing at all. The numbers below illustrate general content consumptions habits: how and where people of different ethnicities prefer to consume content.

As seen from a content consumption report, African Americans are the most active television watchers, followed by Hispanics, who also prefer mobile internet and radio. When it comes to Asian Americans, they don’t seem to be active TV watchers or radio listeners.

1. CRM and DMP for segmentation

According to the Interactive Advertising Bureau, predictive analytics and cross-channel measurement are what 50% of data-centric companies are striving to have in their organizations. Practitioners see a growing need in proprietary data centralization systems since they remove reliance on third-party data management organizations. Such technologies, like CRM and DMP, centralize storage of all data assets, which is crucial if you market campaigns globally.

CRM makes it easier to retain existing consumers, encouraging greater user activity during promotional campaigns and increasing the sum of the average check. Additionally, DMP is also focused on customer acquisition, since it’s capable of look-alike modeling (finding a new audience similar to the existing). Ready-made user segments generated by DMP may be further adjusted to DSP (demand-side platform) in order to personalize the experience for every segment of your multicultural audience.

2. Content personalization for segments

In order to understand how it’s happening on a cultural level, the marketer may run a conjoint analysis. This analysis consists of real-life scenarios and statistical modeling of market decisions. It is widely used for defining appropriate pricing, product configuration and other marketing nuances.

The next step will be the actual designing of the creative and testing the best variants on A/B testing software. Preferably, the testing should start a week or two before the campaign launch.

At this stage, do not overestimate the human factor. Remember, your multicultural campaign strategy should not backfire and turn your efforts into something like a SNL Cheetos commercial. That’s why, in case you have professionals hailing from different ethnic groups on your team, you should kindly ask them to participate in campaign assessment and provide their own opinion considering ad unit relevance and appropriateness.

4. Budget, frequency and dayparting Correct targeting Frequency capping Dayparting Budget limit Analysis

If you are running a multicultural campaign in two languages, it is easy to find out which one performs better. For instance, if one of them generates more traffic, you can recalibrate your future campaign, investing more money in your budget in a campaign featuring a winning variant of creative. Insightful stats can be generated by ad platforms you use, Google analytics and specialized tools that gather the stats across multiple marketing channels.

5 Tips For A Successful Mail Campaign

Internet marketing is not only about having a web page and being present in social networks, but also about making the most of the resources offered by the internet. Now, we have the possibility to provide valuable content to users who request it in exchange for their data, and with this data, we can send them emails explaining in an attractive way what we can do for them and what they can obtain from us, and turn them into customers.

Everything depends on the subject

The subject of the email is what will make the recipient open it or not. It is the first contact that the potential client will have with your mail, so you have to be very careful not to waste the opportunity to get a client because of the subject that sounds like spam.

When deciding whether or not to open a mail, we generally consider two fundamental factors: the subject and the sender. If the sender is unknown, we will rely entirely on the subject to make the decision, and this will not take a few minutes, but it is a quick decision for a few seconds. So it is ideal for the subject to be short, direct and that it offers something to the recipient so that he/she is tempted to open it.

Since the objective is that the reader opens it, the most important thing is the call to action. If we also create a sense of urgency, the user will be tempted to open the mail once he sees it in his inbox and does not leave it for later. Including numbers will increase the opening rate, and some people also include emoticons in the subject.

Another resource is to use the titles of the posts you share in the mail, but keep in mind that you have to hook the receiver by offering something of value.

Use tools to manage your mailing campaigns

Your mailing campaigns will be better managed with a suitable tool to schedule the posts, organize databases, etc. Do not be seduced by the word “free” and choose the cheapest one to save money. Choose the tool that best suits your goals and do not mind spending a little to get much more profitable benefits. Some of the most used (and rightly so) are MailChimp, Mailrelay or Aweber.

Customize the emails with the recipient and do not overwhelm him

Has it ever happened to you that you subscribe to a page and, from that moment, you receive an email every few hours? It’s annoying, right? It is so annoying that you end up unsubscribing, or deleting their emails as soon as they arrive, or blocking all messages that come from that page. It is not a situation in which you would like to find yourself.

Sending a huge amount of emails, in the long run, is counterproductive. Of course, the intention is not to overwhelm your subscribers, but to keep them as well informed as possible. But maybe this is not the most appropriate way. Do not send an email every day; create intervals sending emails. A good option is to send a mail once a week: every Monday to start with strength, every Tuesday for people to focus on returning to work on Monday, every Thursday to dismiss the week. Choose a day and a time when the receivers are more likely to read and keep them.

Once you have defined the frequency with which you will be sending your mail, use the database to personalize the recipients. A personalized email calls more attention than one that is noted to be generic and is intended to be sent in bulk, so that, if you can include the name of the recipient in the mail or in the subject, do it. In fact, a personalized matter has a higher opening rate than a non-personalized. If the recipient gives the impression that he is receiving personalized content exclusively for him, he will not be so reluctant to open the mail. With the database, you can personalize the message with the names of the recipients, the place where he lives, the contents that most interest him, etc.

Send valuable content

We have to create content with the same frequency with which we elaborate email campaigns because if not, we will not have anything to send. You must send valuable content so that the recipient is tempted to open not only the mail but also what you are sending in it.

If you do not see yourself capable of creating enough valuable content each week to include them in your mail strategy, do not do it. Don’t stress yourself because you will end up writing anything and what you think is a quality content at best is a small trip caused by the rush and that will not please the receiver very much. If you cannot send valuable content every week, for example, change your mail strategy and send newsletters every fortnight, and you’ll have more room to create these contents. As we have already said, we should not burden recipients with messages day after day and it is not so much about sending three weekly mails; the important thing is that the frequency is constant and that the content is of quality so that your subscribers find it useful.

In the end, the content is the key

In an email, we have to say everything we want in the smallest possible space, in a clear and concise way. The trick to achieving this is, simply, practice. Read and write as possessed daily not only to improve how you write but also how you organize the ideas you have in your head and the messages you want to convey.

If, for example, the newsletter talks about the contents of some specific posts of your blog, you have to know how to sell all those posts in a few lines, always leaving a little space for the imagination so that the recipient decides to go to those articles and read them in their entirety.

Docker Tutorial For Beginners: Basics, Architecture, Containers

What is Docker?

Docker is a software development platform for virtualization with multiple Operating systems running on the same host. It helps to separate infrastructure and applications in order to deliver software quickly. Unlike Hypervisors, which are used for creating VM (Virtual machines), virtualization in Docker is performed on system-level, also called Docker containers.

As you can see the difference in the image below, Docker containers run on top of the host’s Operation system. This helps you to improves efficiency and security. Moreover, we can run more containers on the same infrastructure than we can run Virtual machines because containers use fewer resources.

Virtualization in Docker vs Hypervisor

Unlike the VMs which can communicate with the hardware of the host (ex: Ethernet adapter to create more virtual adapters) Docker containers run in an isolated environment on top of the host’s OS. Even if your host runs Windows OS, you can have Linux images running in containers with the help of Hyper-V, which automatically creates small VM to virtualize the system’s base image, in this case, Linux.

In this Docker tutorial for beginners, you will learn Docker basics like:

Why use Docker?

Docker is computer software used for Virtualization in order to have multiple Operating systems running on the same host

Docker is the client-server type of application which means we have clients who relay to the server

Docker images are the “source code” for our containers; we use them to build

Dockerfile has two types of registries 1.) public and 2)private registries

Containers are the organizational units of Docker volume. In simple terms, an image is a template, and a container is a copy of that template. You can have multiple containers (copies) of the same image.

Docker Architecture

Now in this Docker container tutorial, let’s talk about Docker main components in the Docker Architecture:

Docker Architecture

Docker Engine

Docker is the client-server type of application which means we have clients who relay to the server. So the Docker daemon called: dockerd is the Docker engine which represents the server. The docker daemon and the clients can be run on the same or remote host, and they communicate through command line client binary, as well as a full RESTful API to interact with the daemon: dockerd.

Docker Images

Docker images are the “source code” for our containers; we use them to build containers. They can have software pre-installed which speeds up deployment. They are portable, and we can use existing images or build our own.

Docker Registries

Docker stores the images we build in registries. There are public and private registries. Docker company has public registry called Docker hub, where you can also store images privately. Docker hub has millions of images, which you can start using now.

Docker Containers

Containers are the organizational units and one of the Docker basics concept. When we build an image and start running it; we are running in a container. The container analogy is used because of the portability of the software we have running in our container. We can move it, in other words, “ship” the software, modify, manage, create or get rid of it, destroy it, just as cargo ships can do with real containers.

In simple terms, an image is a template, and a container is a copy of that template. You can have multiple containers (copies) of the same image.

Below we have an image which perfectly represents the interaction between the different components and how Docker container technology works.

What we have several dockers commands docker pull, docker run.. we will talk more about that later.

How to install Docker on Linux/Ubuntu

Below is a step by step Docker installation process on Linux/Ubuntu:

Step 1) To install Docker, we need to use the Docker team’s DEB packages.

For that, Some prerequisite Ubuntu packages are required.

Use the below command to install Ubuntu packages

$ sudo apt-get install ca-certificates curl software-properties-common

*the sign “” is not necessary it’s used for the new line, if want you can write the command without using “” in one line only.

Step 2) Add the official Docker GPG key with the fingerprint.

Use the below Docker command to enter the GPG key

Step 3) Next, Add the Docker APT repository.

Use the below Docker command to add the repository

$ sudo add-apt-repository $(lsb_release -cs) stable"

You may be prompted to confirm that you wish to add the repository and have the GPG key automatically added to your host.

The lsb_release command should populate the Ubuntu distribution version of your host.

Step 4) After adding the GPG key,

Update APT sources using the below Docker command

$ sudo apt-get update

We can now install the Docker package itself.

Step 5) Once the APT sources are updated,

Start installing the Docker packages on Ubuntu using the below Docker command

$ sudo apt-get install docker-ce

The above-given command installs Docker and other additional required packages. Before Docker 1.8.0, the package name was lxc-docker, and between Docker 1.8 and 1.13, the package name was docker-engine.

NOTE: Docker for Windows requires Windows 10 Pro or Enterprise version 14393, or Windows server 2024 RTM to run

How to use Docker using basic Docker Commands

Here is how to use Docker using basic Docker commands:

The most basic command we must run after installing Docker is $ docker info as we said previously.

$ sudo docker info

You should get the similar or following result

As we can see in the above Docker example, we have information about docker containers how many are running, paused or stopped and how many images we have downloaded. So let’s get our first image in this Docker commands tutorial.

$ sudo docker pull alpine

With this command we are telling docker to download the image alpine, to pull it from the public registry, the latest version which is set by default.

*alpine is a minimal Docker image based on Alpine Linux with a complete package index and only 5 MB in size.

If we want to run the image as a container, we will use the following command in this Docker tutorials guide.

$ sudo docker run -i -t alpine /bin/bash

If we run the command, we will be sent directly to the alpine’s terminal. The -i flag keeps STDIN open from the container, even when you are not attached to it. This persistent standard input is one half of what you require for an interactive shell. The -t flag is the other half and which instructs Docker to assign a pseudo-tty to the container. This offers us an interactive shell in the new container. We exit the container with a simple exit command.

Now in this Docker basics tutorial, we can try running an Ubuntu image.

$ sudo docker run -it ubuntu /bin/bash

You can notice docker checks for the image locally, and if it’s not there, the image is pulled from the image library automatically, and once again we have an interactive shell running. We can also name the containers as we run them.

$ sudo docker run –-name our_container -it ubuntu /bin/bash

and we exit again.

We can also run container we previously created, without an interactive shell.

$ sudo docker start container_name

And stop the container writing docker stop container_name

$ sudo docker stop container_name

If we want to see all running containers, we just run

$ docker ps

And for all containers we add “- a”at the end of this same command, like this docker ps -a.

This command shows Container’s ID, which image is using when was created, running status, exposed ports and randomly generated name for the container for easier management.

When we run containers, we would also like to know how much resources they are using, for that purpose we can use the command.

$ docker stats

You can also see which images we have downloaded locally and info about them.

$ sudo docker images

The command in the above Docker example displays the docker image with a tag which shows our image version, a distinctive image ID, when was created and image size.

What is Virtualization?

Earlier, the process for deploying a service was slow and painful. First, the developers were writing code; then the operations team would deploy it on bare metal machines, where they had to look out for library versions, patches, and language compilers for the code to work. If there were some bugs or errors, the process would start all over again, the developers would fix it, and then again the operational team was there to deploy.

There was an improvement with the creation of Hypervisors. Hypervisors have multiple Virtual machines or VMs on the same host, which may be running or turned off. VMs decreased the waiting time for deploying code and bug fixing in a big manner, but the real game changer was Docker containers.

Important Docker Commands

Below are the important Docker commands:

Command Description

docker info Information Command

docker pull Download an image

docker run -i -t image_name /bin/bash Run image as a container

docker start our_container Start container

docker stop container_name Stop container

docker ps List of al running containers

docker stats Container information

docker images List of images downloaded

Docker Cleanup Kill all running containers.

An Introduction On Etl Tools For Beginners

This article was published as a part of the Data Science Blogathon.

Introduction on ETL Tools

The amount of data being used or stored in today’s world is extremely huge. Many companies, organizations, and industries store the data and use it as per the requirement. While handling this huge amount of data, one has to follow certain steps. Whenever we start working with data, specific words/terms come to our minds. For example, data warehouses, databases, attributes, ETL, data filtering, etc. In this article, we are going to have a brief introduction to one such term named ETL.

What is ETL?

ETL stands for extract, transform, load. Let’s see these terms one by one.

Extract:

It means extracting data from its source which can be an application or another database. Extraction can be divided further into two types:

a) Partial extraction

b) Full extraction

Transform:

It means transforming the raw data which has been extracted from sources. Transforming includes filtering the data, cleaning the data, mapping and transforming data, etc. This step may include some simple changes to source data or some multiprocessing which includes multiple data sources.

Load:

It means converting transformed data into the target database. The target databases can be DataMart, Data Warehouses, or databases. These destination sources are used for analytical purposes, planning business strategies, etc.

In short, the ETL tool performing the above three steps ensures that the data is complete, usable and as per the requirement for further processes like analysis, reporting, and machine learning/artificial intelligence.

Where to use ETL? Machine Learning and Artificial Intelligence

Machine Learning and Artificial Intelligence include a lot of data. The cloud is the only feasible solution to store this huge amount of data. Besides, both of these techniques require large datastores for analytical model building and training. Cloud-based ETL tools are useful here to both migrate large amounts of data to the cloud and transform them to be analytics-ready.

Data Warehousing

Many of the enterprisers use ETL tools to collect data from various sources, then transform it into a consistent format and load it into a data warehouse. Then business intelligence teams can analyze the data stored in data warehouses for business purposes. Data warehouses play an important role in various business intelligence functions. Also, they act as a key component in creating dashboards/reports.

Data Migration

Data Migration is the process of transferring data from one system to another while changing the storage, database, or application. ETL plays an important role here. ETL tools help in integrating the contextual data which can be further used by business analysts/marketers for personalized marketing, improving the user experience, or in understanding customer behavior.

Why use ETL?

There are plenty of reasons why ETL is being used. ETL provides a method of moving data from various sources into a data warehouse. It helps companies to analyze their business data and further helps in making critical business decisions or planning marketing strategies. Sample data comparison can be performed between the source and target systems with the help of ETL. ETL offers deep historical context as well, which can be used for various business purposes. Besides, ETL helps to migrate the data into a data warehouse.

ETL Challenges Loss of Data/Irrelevant data

There is a possibility that some of the data is lost or data gets corrupted because some steps are not performed correctly while transforming or loading the data. Some irrelevant data can also be there due to such mistakes.

Disparate Data Sources

Sometimes the data sources may not be aligned or mapped properly. In such cases, dealing with these data sources becomes a big challenge.

Problems with data quality and integrity

Sometimes while normalizing or transforming the data, there can be performance issues. This may lead to loss of data quality or data integrity. Hence, it becomes another big challenge while using ETL.

1. SAP Data Services

2. Oracle Data Integrator

These programming languages include Python, Java, SQL, Spark, and Hadoop. These types of ETL tools provide the greatest flexibility. Although, they require a lot of effort.
