What's the best email marketing tool under $50 a month?

For most small businesses, MailerLite delivers the most capability for the least money in 2026 — clean automation and a solid free tier that scales affordably well under fifty dollars a month. Brevo is the better pick if you send in spiky bursts, since it can bill by emails sent rather than by contact count.

Why are people leaving Mailchimp?

Mailchimp's pricing climbs quickly as your contact list grows, and its habit of counting unsubscribed and inactive contacts toward your billable total frustrated a lot of small senders. Repeated price increases pushed many users to look at MailerLite and Brevo, which tend to be cheaper for the same list size.

Do these tools have real free tiers?

Yes. MailerLite and Brevo both offer genuinely usable free plans — MailerLite caps by subscribers, Brevo by daily send volume. Mailchimp has a free tier too, but its limits are tighter and the jump to paid is steeper, which is exactly why budget-minded senders compare alternatives.

Best Email Marketing Under $50/Month 2026: MailerLite vs Brevo vs Mailchimp

Mailchimp spent years as the default, then spent the last few raising prices and counting contacts in ways that annoyed small senders. The result: a steady exodus, and a real question for anyone on a budget — what's the best email marketing under $50/month in 2026?

We put MailerLite, Brevo and Mailchimp head to head on the only things that matter to a small business: free tiers, automation, and what you actually pay as your list grows.

The quick answer

For most small businesses staying under $50/month, MailerLite is the best value — clean automation and affordable contact-based pricing. Pick Brevo if you send in bursts and want to pay per email instead of per contact. Stay on Mailchimp only if you're already deep in its ecosystem and the price climb hasn't bitten yet.

How the billing models differ

This is where the money leaks. Mailchimp and MailerLite bill by contact count, so a growing list grows your bill. Brevo bills primarily by emails sent, which can be dramatically cheaper if you have a large list you email infrequently.

	MailerLite	Brevo	Mailchimp
Billing basis	Per contact	Per email sent	Per contact
Free tier	Solid, subscriber cap	Solid, daily send cap	Tight limits
Cost as list grows	Stays reasonable	Flat if you send rarely	Climbs fast
Automation	Clean, capable	Capable + SMS/CRM	Capable but pricier
Counts inactive contacts	No	No	Often yes

Pricing changes — verify live tiers

Email pricing tiers move often, and Mailchimp in particular has changed them repeatedly. Treat these as the shape of the difference and confirm current contact and send limits on each vendor's pricing page before you migrate.

Brevo — best if you send in bursts

Brevo's per-send billing is the killer feature for the right user. If you have thousands of contacts but only email occasionally — say a monthly update or seasonal campaigns — you can keep a big list essentially free or near-free. It also bundles SMS and a light CRM, which is handy if you want fewer separate tools.

Selling products? Look at Klaviyo

If you run an ecommerce store, raw email price matters less than revenue per send. Klaviyo costs more but its deep store integrations and segmentation typically earn it back for product sellers. It's overkill for a simple newsletter, but the right call when email is your sales channel.
