The Best Free Email Marketing Tools for 2021 [Guide] - Litmus (2024)

As far as marketing channels go, email remains a powerhouse with 4 out of 5 marketers preferring to give up social media than email marketing. Why? Businesses drive more revenue—$36 for every $1 spent—and brand awareness with email than ever before.

However, we all know your strategy needs to adapt to your customer’s preferences. If you want to keep up with the latest consumer expectations (and have the time to do it), you need to find the right email marketing platform for your business that’ll help you be both effective and efficient.

Still, 40% of marketers say email marketing is under-resourced at their company. And only 12% plan to add email staff. We get it. It can be tough taking your email marketing program to the next level on a tight budget—but it’s possible.

So, what do you need in your toolkit to master email marketing in 2021?

We teamed up with our friends at HubSpot to find out:

  • How to improve your email marketing strategy in 2021

Email marketing trends to watch in 2021

The Best Free Email Marketing Tools for 2021 [Guide] - Litmus (1)

Every year, it seems there are new trends, features, and best practices for email marketers.

So, how do marketing teams make the most of their time?


To get the most out of your email marketing strategy, you need to identify which tactics have the most significant impact, and focus your energy there first.

Here are the top trends in email marketing for 2021.

Segment your email list

At its core, marketing aims to build a relationship between your business and your customers. If you want to build strong relationships with email marketing, segmentation is crucial.

More than 70% of consumers have received an offer via email that demonstrates the sender clearly doesn’t know their recipient.

Sending mistargeted emails can destroy the brand trust you took precious time to build or even cause someone to unsubscribe from your list. Businesses that generate the highest return on investment (ROI) from email marketing in 2021 will know exactly how to message each customer segment.

Personalize emails to your subscriber

When surveyed, 90% of Americans claimed that personalized emails are more appealing. Personalization can be as simple as adding a customer’s first name or sending an abandoned cart notification.

Customers expect businesses to know who they are, which means you need to personalize your email subject lines and content. Personalization increases open rates, conversion rates, and conversion values.

Set up email automation

About 60% of marketers say boosting email personalization is a priority—even more so for those in ecommerce, retail, and consumer goods. But keeping up with multiple customer segments and personalized messaging can quickly eat up your team’s time. So to get the most out of your marketing strategy, you need tools to automate your email sends.

It’s no wonder that expanding the use of email automation is marketers’ number one priority according to our 2020 State of Email Report, Fall Edition. Automated emails empower your team to send the right information at the right time. When you automate emails, you can take the time to plan your email strategy carefully.

And if you have a longer sales funnel, automation allows you to nurture leads more efficiently. By setting up the right workflows, you open up time for your team to focus on high-value deals and strategy.

What to look for in a free email marketing tool

Not all marketing tools are equal, and this is especially true for free tools. Before you find the right software for your business, you need to know which features are best.

When it comes to free email marketing software, we recommend finding a provider that offers a template library, A/B testing, customization options, and is easy to use. We also recommend taking the time to see what is included in the free plan.

Template library

Email templates make it easier for you to establish consistency with your brand. That’s why 67% prefer building emails with a WYSIWYG editor, drag-and-drop visual editor, or design library.

Find software where you can create and store templates for each of your communication types, including welcome emails, newsletters, and offers.

A/B testing

Your email marketing strategy should be as unique as your audience. So, to learn what works best for them, you need to A/B test your emails. In fact, 90% of marketers A/B test, with more than a quarter doing so often or always. This isn’t something you can overlook.

The best email marketing tools offer simple A/B testing for variables such as subject line, imagery, send time, and email content.

Easy to use

About 50% of marketers say optimizing their email marketing process is a priority. So you don’t want to choose a free tool only to be slowed down by a learning curve. It’s just not worth it.

Look for email tools that offer a drag-and-drop email editor in addition to templates. And, before you make your final decision, read through reviews to see which software is most user-friendly.

Customization options

Customization is essential for email marketing because it allows you to establish a brand image. So it’s no surprise that 70% of marketers have email brand guidelines. Ideally, your email marketing tools empower you to choose fonts, styles, and colors that fit your brand.

What’s included in the free plan

Finally, when choosing your email marketing tool, take time to see what’s included in the free plan.

Generally, email marketing has one of the highest ROIs of all marketing platforms. However, email can quickly become expensive, depending on the software you choose.

Email marketing tools often charge based on your number of subscribers and how many emails you send each month.

36% of marketers are dissatisfied or neutral about their email service provider, so before choosing an email marketing tool, make a list of the most important features to you. Use that list as you compare software options to find the right fit for your company.
