Your content dropped in the search rankings thanks to a new Google update, or maybe your Facebook ads aren't generating leads like they used to. Either way, one thing is clear: when you don't own the channels where you reach customers, the ground can always shift beneath you. That's where email marketing shines.
Maybe you've been sending customers emails via bcc in Gmail, and now you're ready to find a better solution—something actually built for businesses.
Better often means more expensive, but there's an entire ecosystem of free email marketing tools available, and they have all the features you'll need to build out your email marketing (and then some).
We researched and tested dozens of free email marketing apps to find the best ones for a variety of use cases and business types. Here are the seven best free email newsletter services.

What to look for in a free email marketing service
How we evaluate and test apps
All of our best apps roundups are written by humans who've spent much of their careers using, testing, and writing about software. We spend dozens of hours researching and testing apps, using each app as it's intended to be used and evaluating it against the criteria we set for the category. We're never paid for placement in our articles from any app or for links to any site—we value the trust readers put in us to offer authentic evaluations of the categories and apps we review. For more details on our process, read the full rundown of how we select apps to feature on the Zapier blog.
Full-featured email marketing apps and free ones are far from mutually exclusive. There are tons of options that offer flexible subscriber and send thresholds along with the robust features small businesses need—for free. If you're just getting started with free marketing tools or want to try out a few options before committing to a paid plan, you have plenty of choices.
Here's what we looked for when testing free email marketing software:
The number of subscribers and sends included for free. Some free email marketing platforms are generous in this regard, offering thousands of free sends per month, while others include low caps that mean your "free" platform isn't free for very long. We kept this in mind while testing.
Email templates and customization. You shouldn't have to start your email marketing operation from scratch. The best options come with at least a few fully-designed and professional templates to get your free email campaign started.
Audience segmentation. Success with email relies on being able to deliver the right emails to the right people at the right time. For growing businesses, that means you need capable audience segmentation features with any free email campaign software you choose.
Automation. From transactional emails to triggered campaigns and more, a growing business needs to be able to automate email marketing as your efforts scale.
Scalability. Speaking of, just because you're starting by doing your email marketing for free, it doesn't mean you won't grow out of it. The best free email marketing software can grow with your business—from free to paid when necessary, adding more features and higher limits as you go.
Full email marketing features. There are plenty of capable apps designed for one particular type of email (like newsletters, for example), but for our purposes here, we focused on full-featured apps you can use across your email marketing operation.
With those criteria in mind, here are the best free email marketing apps.
Best free email marketing software for growing email marketing programs
One of the most popular email marketing apps thanks to its friendly branding, Mailchimp is a great place to start your email marketing program if you're planning to scale it quickly. The app includes a landing page builder, customer journey mapping, marketing automation, list segmentation, retargeting ads, and even A/B testing—all in its free plan.
An approachable editor that includes helpful tips and best practices along the way makes Mailchimp an accessible option for both new and experienced email marketers. For example, when setting up a subject line, a sidebar reminds you about recommended character length, emoji use in subject lines, and more.
Once you're ready to move beyond what the free plan offers, Mailchimp makes scaling accessible with three different paid tiers. Plus, Mailchimp can handle email programs of any size: if you can afford to let it grow with you, you'll never have to switch to another app.
Mailchimp integrates with Zapier, allowing you to do things like automatically subscribe new form responders, leads, or spreadsheet entries to a Mailchimp list.

Best free email marketing software for advanced email marketers
MailerLite doesn't offer pre-made templates for its free newsletter service, but the dynamic, pre-designed content blocks more than make up for the lack of templates. With blocks for highlighting multiple articles, videos, RSS lists, products, apps, events, and more, MailerLite helps experienced email marketers make quick work of building new campaigns and custom templates.
Your emails can include more than just text and images, too. There's a countdown timer that dynamically shows the time remaining until you launch a product or before a sale is over. You can add product details, embed a video, pull in your most recent blog posts with a dynamically updating RSS block, and more. It's a great way to send interactive emails instead of just digital letters.
Beyond email content, MailerLite also includes robust automation and audience segmentation features in the free plan. An intuitive builder makes quick work of mapping out automation workflows. You can create both persistent and one-time segments and view aggregate statistics by segment, too.
Plus, MailerLite integrates with Zapier—meaning you can automate things like adding new MailerLite subscribers from Google Sheets and sending Gumroad customers to MailerLite.

Best free email marketing tool for eCommerce businesses
Moosend isn't the most streamlined email marketing app we tested, but it makes up for that with generous allowances on the free plan and powerful segmentation options for eCommerce businesses.
The email builder works as you expect with drag-and-drop functionality to add elements and a rich text editor. Once you connect your eCommerce site, click over to the Revenue Dashboard tab to see an overview of exactly how your email marketing efforts lead to sales.
Compared to other apps we tested, it takes a few extra clicks to build a new segment. But even free users can segment lists by crucial eCommerce dimensions like average order value, subscribers who add a particular product to their cart, total spending, and more. Moosend also includes automation features with its free plan: over a dozen automated "recipes," including sequences for abandoned carts, upsells, and customer loyalty.
Moosend integrates with Zapier, opening up connections with tons of other apps and automated workflows for things like adding new Moosend subscribers from new leads and verifying email addresses for new Moosend subscribers.

The drag-and-drop editor works how you expect and includes support for dynamic content blocks. You can even personalize dynamic blocks based on your customer segments.

Both are available on the free plan and include several workflow templates to help you build out automations faster.
