Digital marketing has seen a huge rise in recent years and email marketing has been at the top of all digital marketing channels.

Businesses, small and large, are all looking for wider audiences and greater reach and better conversions.

Good email marketing campaigns can help boost sales, image and loyalty among many things and this is what keeps attracting most brands and marketers toward it. Let’s look at what email marketing is, why it is important and what are some of the best email marketing platforms of 2021 to find one that suits you.

What Is Email Marketing?

Email Marketing is the digital marketing practice of sending emails that engage and communicate with prospects and customers of businesses. These emails may promote the business, sell products or services or simply provide valuable information to readers.

Many think that email marketing is a thing of the past and there are newer channels that provide better, more engaging and profitable digital marketing opportunities. This could not be farther from the truth. Email marketing strategies are indeed old and may seem basic from a user’s perspective but they have held the highest ROI for any digital marketing strategy for decades.

In the year 2019, around 3.9 billion people used email globally and this number is expected to hit 4.4 billion by the year 2024 according to some studies.

The Importance of Email Marketing

Email Marketing is an excellent way to convert prospects, engage customers and build brand image and loyalty. If your digital marketing strategy does not incorporate email marketing campaigns, you may want to rethink and reshape your strategy to do so.

It is essential for any B2B or B2C business to use a strong email marketing strategy for their digital marketing. Because when it comes to digital marketing, email is the undisputed champion for conversions and building good customer relationships.

There are many reasons email marketing is important for any business, large or small.

Brand Loyalty and Image

A good email marketing strategy can help your brand build trust and loyalty among your prospects and customers. This, in turn, improves your overall brand image and market perceptions of your business. It is not hard to see how brand loyalty and image can boost conversions and sales.

Inexpensive and Cost Effective

Research shows that the ROI of email marketing was $40 for every dollar invested in 2018. This and the low barrier to entry make it an excellent choice for smaller businesses that cannot afford other, relatively expensive marketing strategies.

Although small businesses can benefit greatly, larger businesses equally reap the strong returns from email marketing and continue to incorporate it in their marketing strategies.

Effective Results

Ranked as the most effective digital marketing strategy in 2018 by many studies, email marketing has led the digital marketing ROI of any strategy for decades. What is even more interesting is that after all this time, it is still improving and growing larger every year.


The inherent nature of email addresses as a primary mailing hub is such that users tend to maintain them for decades. Whereas they may change addresses and handles more often and easily on other channels like social media platforms or contact numbers.

This means investing in and developing an email list can last your brand or business for a long time without having to update for changes in user addresses.

Insights and Measurability

User engagements and responses on emails provide immediate results that give you relevant data on prospects and customers. This allows you to measure your email marketing campaign with greater accuracy and adapt immediately according to requirements.

Email marketing platforms or software services often give detailed analyses of the campaign using tools that help measure and identify your campaign’s strong and weak points.

What Is an Email Marketing Platform?

Developing a rich mail list and sending out thousands of emails can take a lot of time and quickly become inefficient if not managed and controlled properly. This is where you require software and automation to help you better utilize email marketing strategies.

An email marketing platform or software service does exactly this. They provide you the necessary software, automation, tools and management skills you need to conduct a successful email marketing campaign for your brand or business.

Most email marketing platforms have features that provide automation, segmentation, reporting and management tools and they all have different features to choose from for your email marketing strategy.

Some provide all-in-one solutions while others provide simple and easy-to-use automation for your campaigns. There are two main types of email marketing software, they are:

  1. Packaged Software
    These are installed directly in to your computer for automation of email marketing. Usually these will cover all bases but are limited to a single device for operations and control. They have two main advantages over cloud based software:
  • Mail list is stored locally on your internal computers.

  • Less expensive than cloud-based software.

  1. Cloud-Based Software
    These are accessible from any computer that has a working internet connection because they are a cloud based software. They have many other advantages over packaged software including:
  • Automatic software updates.

  • Email servers are certified and focused for mass distribution, increasing delivery rates.

  • Single provider will maintain all web spaces for editors and email servers.

  • No IT maintenance costs of problems.

The Best Email Marketing Platforms of 2021

We have researched and compiled a list of the best email marketing platforms for you so you do not have to. We will cover them in detail and discuss the pros and cons of each as we go.

Here are our leaders of the best email marketing platforms of 2021


ActiveCampaign is an American platform that claims to be an all-in-one marketing platform with the goal of sending fewer emails with greater results. They are highly focused on automation and as such, they provide unparalleled automation in the field.

Based on visitors’ behavior you can automate almost everything on your website using if/when/then logic. They also offer a personal consultation call and a spam analyzing tool which is unique from other platforms.

They have an added aspect of machine learning for sending emails among other modern email marketing features. All their plans have no limit to the number of emails, and the pricing works on the number of contacts instead.

As the number of contacts increases, the pricing rises and features start to become limited. This means that the more contacts you have, the lower tier your plan becomes. This is an odd way of pricing compared to all other platforms.

If you pay yearly instead of monthly, it will reduce the cost of plans across the board. There are no money-back guarantees and plans start at $9 per month for 500 contacts. There is, however, a 14 day free trial that has limited features.

Adding contacts to the software is easy and straightforward with an added feature of automatic transfer of email list from any other service. You have to tag each contact to better organize them. There are multiple options for the type of campaign you want to start including:

  • Automation
  • Standard
  • Date-Based
  • RSS Triggered
  • Split Testing

This is where the previous tagging of contacts is important because you can only add lists of contacts to your campaigns and not individual or all contacts.

The editor tool has 21 templates and a few layout options to choose from when creating emails or you can also put in a custom HTML code. The design tool adopts a drag & drop function with some added design options for every component. The image editor within the email editor is easy-to-use and can save you some time on image editing.

The summary page at the end has nice tracking features for different elements, scheduling of email launch and a unique spam checker that shows how much your email is considered spam. This is a unique feature not found with most other platforms.

They have a mobile app but it does not offer the editor, it is more for informational purposes. It will show you reports, track customer activity and give access to your Customer Relationship Management (CRM).You can however access the editor through a mobile web browser.

Customer support is only available during business hours through chat and email but call support is limited to subscribers of higher tier plans.

  • Spam checker


  • No free plan or trial

MailChimp is by far the most popular email marketing platform to date. They have a market share of almost 70% which is extreme market domination to say the least. Owning almost 70% of any market is borderline monopoly.

For comparison, its biggest competitor Constant Contact rakes in a little over 6% and the other 250 plus platforms rake in around 18%. This makes MailChimp King Kong rather than a chimp in the jungle of email marketing platforms.

The reason for this could be the fact that they offer a free plan with up to 10,000 emails per month to 2,000 contacts. There is the catch of a small ad on the footer of each email, but that seems like a low price to pay for what is essentially a steal.

The pricing is based on the number of contacts and plans start at $9.99 per month for 500 contacts. They offer a pay-as-you-go option from the ‘Essential’ plan that is very flexible for users, you can prepay for MailChimp credit which can be used to send out your emails.

Apart from this, they offer more than 200 integration options with social media platforms and other applications which make for good social media features. The software itself is very user-friendly and has a guide that walks you through the process which is great for beginners.

After setting up an account, you can import or copy paste contacts, then add tags, information and statuses of contacts. You can change these later if needed. You then set up your campaign and can create emails by selecting templates and layouts or with custom HTML code or simple text.

The templates and layouts feature a drag & drop tool and the built-in image editor saves you time on email developments. You can view the email in mobile, desktop or inbox view and double check everything in the summary page before sending.

The email builder lacks the modern drag & drop feature, leaving you with custom HTML code or plain text options.

The preview option allows you to double check all the content before sending out immediately or scheduling the send time for a later date. ConvertKit lacks a mobile application but makes up for it by allowing you to utilize all the features through a mobile web browser.
