Best Free Email Marketing Tools — Mailchimp Alternatives in 2025

Mailchimp used to be the go-to free email marketing tool for small businesses and creators. In 2023 they significantly reduced their free tier, removed automation, and limited contacts to 500. Meanwhile Brevo and MailerLite have built genuinely generous free plans that are now better than what Mailchimp used to offer.

Brevo (Free — 300 emails per day, unlimited contacts)

Brevo, formerly known as Sendinblue, offers the most generous free email marketing plan available. You can store unlimited contacts and send up to 300 emails per day on the free plan. That is 9,000 emails per month for free.

Brevo also includes basic email automation on the free plan, which Mailchimp removed from their free tier. For small businesses sending a weekly newsletter to a list under 5,000 people, Brevo's free plan covers everything.

MailerLite (Free — up to 1,000 subscribers, 12,000 emails per month)

MailerLite has one of the cleanest email builders available. The free plan allows up to 1,000 subscribers and 12,000 emails per month, includes landing page builder, basic automation, and pop-up forms.

For creators, bloggers, and small businesses just starting to build an email list, MailerLite's free plan is excellent.

How Mailchimp compares today

Mailchimp's current free plan allows 500 contacts and 1,000 emails per month. There is no automation on the free tier. The interface is cluttered with upsells. Most users who were on Mailchimp's old free plan now have a better option elsewhere.

Which should you pick?

- Large contact list, want unlimited storage → Brevo - Building a new list, want clean interface → MailerLite - Already paying Mailchimp and want to save money → Either one

Migrating from Mailchimp

Both Brevo and MailerLite support direct import from Mailchimp. Export your Mailchimp audience as a CSV and import it. Both platforms have step-by-step guides and the process takes about 15 minutes.

The bottom line

Mailchimp built its reputation on a generous free plan that no longer exists. Brevo and MailerLite have filled that gap with better free tiers. If you are paying for Mailchimp or frustrated with their current free plan limitations, switching takes 15 minutes and saves you money immediately.
