Best Email Newsletter Software in 2026

Mailchimp remains the most familiar name in this group, and that familiarity has a practical benefit. It connects with a long list of shop, booking, and customer tools, so a small business can often link its existing stack without extra work. The email builder is polished, and scheduled sends, tests, and reports are easy to find.

The catch is the billing model. Mailchimp charges by contacts, and the free plan covers only 250 contacts and 500 sends a month. A growing list can therefore become expensive sooner than the headline price suggests, so check the price at your actual list size before you commit.

Kit, formerly ConvertKit, is built around creators rather than general marketing teams. Forms, landing pages, broadcasts, and tags sit close together, which makes it simple to turn a reader into a buyer of a course, guide, or paid newsletter. The free plan is unusually generous on subscriber count, even though advanced automation needs a paid plan.

That generosity ends at 10,000 subscribers, after which the paid price applies. For a creator who already sells digital products, the commerce tools may justify the step up. For a simple monthly newsletter, a cheaper tool may do the same job.

Beehiiv treats the newsletter as the main product, not as one channel among many. Each post can also serve as a web page, and growth features such as referrals, recommendations, and an ad network are built in. The free plan allows unlimited sends, which is a real advantage for a frequent publisher.

Paid plans are the trade-off. Lite starts at 59 dollars a month on monthly billing for the smallest paid tier, and the price rises as the list grows. Writers who plan to monetize may still come out ahead, since beehiiv takes no cut of paid subscription revenue on paid plans, apart from payment processing fees.

Substack is the simplest starting point on this list. A writer can publish, send, and collect subscribers without paying a monthly fee, and readers can discover the publication through recommendations inside the Substack app. That network effect is hard for a standalone tool to match.

The cost arrives only when you charge readers. Substack keeps 10 percent of paid subscription revenue, plus payment processing fees, and a custom domain carries a one-time fee. For a free newsletter, that trade is excellent. For a large paid publication, a flat monthly platform may cost less over time.

MailerLite appeals to senders who want a clean editor and a modest bill. Comfort starts at 12 dollars a month for up to 500 subscribers, and the plan structure is easy to read: more subscribers or more sending means a higher tier. Forms, landing pages, and automation are included in useful amounts on paid plans.

The free plan is now a trial-sized tier rather than a long-term home, with 250 subscribers and 2,500 sends a month. That still works for a launch list or a test. Once the list passes that cap, MailerLite stays among the cheaper paid options in this guide.

Brevo, formerly Sendinblue, flips the usual pricing logic. Instead of paying for every contact stored, you pay mainly for how many emails you send. That suits a business with a large database that is contacted selectively, such as a seasonal promotion list. The free plan allows 300 sends a day with unlimited contacts, within its stated limits.

Automation, testing, and advanced reporting sit on higher tiers, and removing Brevo branding can cost extra on lower plans. Read the plan table at your real monthly send volume, not at the default volume shown on the pricing page, to avoid a surprise.

Constant Contact has long served small businesses, clubs, and nonprofits that send regular updates and event invitations. The interface is plain and guided, which helps a team that does not send email every day. Lite starts at 12 dollars a month on monthly billing for the smallest contact band.

There is no ongoing free plan, only a trial, so this is a paid choice from the start. Automation depth also steps up with plan level, so a business that wants custom automation paths should price Standard or Premium at its own list size rather than trusting the entry figure alone.

Buttondown suits writers who want to write and send, without a marketing suite attached. The editor stays out of the way, and the free plan covers a small list. Paid plans start at 9 dollars a month for up to 1,000 subscribers, with a paid subscriptions add-on for writers who want to charge readers.

The trade-off is scope. Buttondown will not match Mailchimp or Brevo for automation, templates, or integrations. If your newsletter is mainly text, sent on a regular schedule, that simplicity is a strength rather than a gap.

Ghost is a publishing platform with newsletters and memberships built in, rather than an email tool with a blog attached. A publisher can run free and paid tiers, keep the full subscription revenue apart from payment processing fees, and shape the site with themes. Self-hosting is also possible for teams with technical help.

That control comes with more setup than Substack or Buttondown. Ghost (Pro) hosting prices vary by member count, so check the current pricing page for your list size. Publishers who want independence from a reader network, and who are happy to manage a site, will get the most from it.
