Top 5 Email Marketing Automation Software Services in 2021

Email marketing is one of the most cost-effective marketing tools. It’s easy to manage, provides full control, and allows you to establish direct contact with your customers.

You can use any method to your contact database, but if you can’t do a competent email campaign, there will be no point in it. If you’re not careful enough, you’ll pay a lot more for fewer features and terrible performance (which eventually will make you lose even more money).

Top 5 Email Marketing Automation Services in 2021


Omnisend is an omnichannel solution that allows you to send messages via email, SMS, and push notifications. You can use Omnisend to create promotional emails, set up automated workflows across channels, analyze past campaign results, run A/B tests, and more.

Generating subscriptions is crucial for long-term success in digital marketing, and Omnisend provides several customizable signup forms. If the traditional signup box isn’t achieving the results you’re looking for, you can quickly set up exit-intent popups, dedicated landing pages, and even gamified email capture forms to catch your audience’s attention.

A large library of themed templates makes it easy to get started with your next campaign. Omnisend’s drag-and-drop editor gives users full control over the design of each email, and custom designs can be saved and used in future messages.

A similar drag-and-drop design lets subscribers tweak every aspect of their automation workflows. Omnisend also streamlines the process of setting up splits—for example, you might want to configure two different sequences depending on whether a customer opens the first email.

Customer segmentation and analysis is another area that differentiates Omnisend from other marketing platforms. Segments will automatically be updated in response to new information, and users can sync their audiences into Facebook, Instagram, YouTube, and Google for lucrative targeting and retargeting opportunities. Omnisend is the perfect way to avoid disruption to identity resolution in a cookieless future.

Finally, Omnisend offers all the tools you need to monitor and analyze the results of each campaign. Reports are built directly into the automation editor, so you can make more informed decisions without having to leave the editor to check your marketing data. Tracking performance and attribution across channels will give you a comprehensive view of your successes and failures.


Free: If you want to test Omnisend out before committing to a subscription, you can always start with a free trial of the Standard or Pro plan. Furthermore, the service is entirely free for email marketing users who send up to 15,000 messages per month. Free users can also create signup forms, view sales and performance reports, and leverage the platform’s segmentation and analytic features.

Standard (starts at $16 per month): Omnisend’s pricing depends on the size of your contact list—for example, a Standard subscription costs $16 per month for an organization with 500 subscribers, but that price rises to $20 per month if you have 1,000 subscribers. Standard users are still subject to a monthly email limit based on their subscriber count, but there are no restrictions on how many messages can be sent per day.
