Evidence brief v0.3 · Updated 2026-05-20
We reviewed official pricing and help pages for seven email marketing and newsletter tools. The current public evidence supports one confirmed before/after free-tier reduction, one triangulated Mailchimp reduction that still needs official dated change evidence, several current free-plan pressure points, and public reaction examples from creators looking for alternatives.
Confirmed signal
MailerLite 1,000 to 500
A dated official help article makes this the only strong before/after shrinkage signal in this first evidence set.
Current constraints
Mailchimp, Omnisend, Brevo
Mailchimp is now a triangulated reduction; Omnisend and Brevo remain useful current-state constraints.
Do not overclaim
No broad index yet
A credible launch asset is stronger when it names the evidence boundary instead of exaggerating a trend.
Strength means how safe the signal is for a public campaign. Strong means dated before/after evidence exists. Medium-high means official current limits plus credible external change evidence, but no official dated change notice yet. Medium means a current constraint exists but a dated change still needs verification.
Confirmed change
Official help article says the Free plan subscriber limit is reduced from 1,000 total subscribers to 500 starting September 23, 2025.
Campaign angle: Keep sending to the first 1,000 subscribers without hitting a free-plan sending lock.
Triangulated change
Official pricing/help pages list Free at 250 contacts and 500 sends. 2026 third-party reporting and Reddit discussion point to a 500-to-250 reduction, but a Mailchimp-dated change notice is still needed.
Campaign angle: If 250 contacts is too small to validate the channel, compare alternatives before building the first list.
Current constraint
Official pricing lists Free with 500 monthly emails and 250 contacts.
Campaign angle: Test ecommerce automations without outgrowing the free contact and send cap in the first campaign cycle.
Current send cap
Official pricing/help content describes a Free plan that can send up to 300 emails per day after approval.
Campaign angle: Avoid daily-send ceilings while keeping predictable campaign volume.
Category context
Official pricing lists a free Newsletter tier up to 10,000 subscribers, with paid tiers and feature needs shaping the upgrade decision.
Campaign angle: Treat as context, not shrinkage: the wedge is when automation or integration needs force a paid decision.
Category context
Official pricing says the free Launch plan includes up to 2,500 subscribers and unlimited email sends; paid plans unlock growth, monetization, analytics, and AI features.
Campaign angle: Treat as context unless a dated feature move is found.
No free-tier wedge
Official pricing emphasizes a free trial and paid marketing automation plans rather than a permanent free email marketing tier.
Campaign angle: Do not position as free-tier shrinkage; use only in paid automation comparisons.
Reaction evidence does not prove a category-wide trend. It does show who is already searching, what objections they have, and what a useful migration campaign must answer.
Reddit r/Emailmarketing
Alternative search
A user said they had just moved from Mailchimp to MailerLite, crossed 500 subscribers, then went back to looking for alternatives after the 1,000-to-500 free-plan email.
GTM implication: The affected audience is not theoretical: users around 500 subscribers are actively comparing substitutes.
Reddit r/Emailmarketing
Migration anxiety
A creator with roughly 520 subscribers asked for a free MailerLite alternative and whether migrating forms and automations would be difficult.
GTM implication: The campaign pack should include a migration checklist, not just an alternative landing page.
Reddit r/selfpublish
Segment signal
Self-publishing authors discussed EmailOctopus and other options after the MailerLite limit change; one user with just over 500 subscribers said the first paid level was not worth it for their send volume.
GTM implication: Creators and author newsletters are a sharper segment than generic small businesses.
EmailOctopus blog
Competitor response
EmailOctopus published a dated competitor-response post comparing its free tier against MailerLite after the subscriber limit change.
GTM implication: The migration moment is already being used by competitors, which validates the need for fast timing.
Reddit r/MailChimp
Alternative search
Users discussed rethinking Mailchimp after the reported 2026 free-plan reduction and compared EmailOctopus, MailerLite, Sender, and other options.
GTM implication: The Mailchimp angle has visible switching behavior, but the dated reduction should stay labeled as third-party reported until official change evidence is captured.
Migration moment to attack first
A competitor can build a precise alternative page, search ad group, migration checklist, and neutral community response around the dated MailerLite change without claiming that the whole category is shrinking.
