MailerLite vs Mailchimp
This comparison is built from three datasets we maintain for every catalog service: documented pricing captured from the vendors' own configurators, the documented-feature matrix compiled from vendor documentation, and user ratings from G2, Capterra and Trustpilot — each value dated at its capture. Neither service has a measured deliverability score yet; we compare only what the data supports.
Editorial verdict — who fits whom
A price-first pick against an ecosystem-first pick. MailerLite's Comfort tier at 1,000 subscribers is $19/mo and already passes our functional filter — automation, API and branding removal included — while Mailchimp enters at $27/mo (Essentials) and needs Standard at $45/mo to pass the same filter (checked 2026-08-19). At 50,000 contacts the gap holds: $319 versus $450 functional (checked 2026-08-21). MailerLite also carries the higher weighted rating — 4.4/5 across 6,668 reviews against Mailchimp's 4.32/5, though Mailchimp's base is far larger at 32,152 reviews (checked 2026-08-21).
Mailchimp documents more overall — 39 of 60 tracked capabilities versus 31, including CRM, SMS and reputation monitoring that MailerLite's pages don't mention (checked 2026-08-21). MailerLite fits budget-driven senders who want the full functional toolkit on the cheapest tier; Mailchimp fits teams that want the broader documented platform. Neither has a measured InboxRatio deliverability score yet.
Measured deliverability
Inbox placement: not yet tested
Neither MailerLite nor Mailchimp carries a measured InboxRatio Deliverability Score yet — measured scores publish as test cycles complete, and we never infer a deliverability comparison from pricing, features or user ratings. When both services have completed a seed-list cycle, this section will show their measured inbox-placement results side by side.

Pricing side by side
Cheapest paid tier covering each volume, and the functional tier — the cheapest tier with automation, API access and vendor-branding removal all included — captured from the vendors' own pricing configurators on monthly billing.

Has InboxRatio tested MailerLite and Mailchimp's deliverability?
Not yet — both services are in the queue for Cycle 0, our first seed-list test cycle across the whole catalog. Measured inbox-placement scores publish only as test cycles complete, so this comparison deliberately carries no deliverability numbers for either service until then. How we test.
