Mailchimp alternative for small newsletters: MailerLite
Compare Mailchimp and MailerLite free contact and send limits, check whether your newsletter fits, and plan a safe migration.

Consider MailerLite if your small newsletter runs out of monthly sends on Mailchimp. Both vendors currently publish a 250-person free allowance, but Mailchimp lists 500 monthly sends and MailerLite lists 2,500. A list above 250 needs a separate paid-plan comparison.
Plan limits checked 14 November 2026 against Mailchimp pricing and MailerLite pricing. Confirm the terms shown for your account before moving. This comparison uses published documentation.

Contacts and active subscribers are different billing labels. Start with the count shown in each account. Check how unsubscribed records, multiple lists and duplicate addresses are treated before using an export total as the billable count. Keep records of opt-outs even if those records do not count toward a plan allowance.
Run the numbers for your busiest month
A newsletter with 200 recipients and four campaigns uses 800 sends before follow-ups. That exceeds Mailchimp's monthly free cap and fits MailerLite's published monthly allowance. Add 40 welcome messages and two reminders to 30 people and the total becomes 900. Count every recipient of each campaign, including campaigns sent to overlapping groups.
For a list of 240, two full-list campaigns use 480 sends. A third campaign would exceed the Mailchimp monthly cap. Two full-list sends on the same day also exceed its daily cap even if monthly capacity remains. Move the campaigns to separate days if timing is flexible, or price another plan if the workflow requires both on the same day.
Choose the plan that fits the workflow
Stay with Mailchimp if your schedule fits and keeping your existing signup forms, templates and reporting saves more time than a migration would. Test MailerLite if the monthly limit repeatedly interrupts a small list and your templates and forms are simple to replace. If your list is near 250, compare paid quotes at the size you expect next quarter and use your normal sending frequency.
Write down the tier you need for each requirement. A custom domain, branding removal, multi-step welcome sequence or role-based access can change which plan fits. Compare the normal renewal cost at the same contact count and sending volume. Include staff time to recreate automations, regenerate templates and update integrations. The switching cost calculator can estimate payback once you have those inputs.
Verify the first send before switching
Recreate one newsletter and one signup flow with addresses your team controls. Verify desktop and mobile layout, sender authentication, personalization, reply-to and unsubscribe. Compare the test counts with your expected counts. Check that suppression survives migration by testing with a seeded opt-out record, without sending it a campaign.
Move gradually. Keep campaign metrics and the original exports available to your team. When the new signup path works, update your most-used embed, inspect the new records and review suppression before a larger send. See the email marketing migration checklist for a staged cutover.
