The MailerLite vs Sender matchup used to be a coin flip between two of the most generous free plans in email marketing. As of mid-2026, it isn't. MailerLite cut its free tier sharply in a June plan restructure, and Sender now wins the free-plan comparison outright — by an order of magnitude.
That leaves a more interesting question than the old send-limit trivia: is your priority the biggest free runway you can get, or the monetization and feature stack you'll want once the list is paying for itself? The two platforms now answer for opposite priorities.
The pricing math, verified
As of July 2026, from both vendors' official pricing pages: Sender's free plan covers 2,500 subscribers and 15,000 emails a month, with paid plans starting at $7/month (Sender pricing, 2026; Sender Standard plan, 2026). MailerLite's free plan, after its roughly June 2026 restructure, allows 250 subscribers and 2,500 emails a month, with paid tiers renamed to Comfort, from $12/month, and Power, from $25/month — increases of about 10–30% over the old plans (MailerLite pricing, 2026; EmailToolTester, 2026).
Older comparisons that pit MailerLite's 12,000 free emails against Sender's 15,000 are describing a plan that no longer exists. On today's free tiers, Sender allows ten times the subscribers and six times the monthly sends. That's not a close call; it's a category difference.
Where each platform actually wins
Sender wins on runway. A list can grow to 2,500 subscribers with a real sending cadence before the first invoice arrives, and the $7/month paid entry keeps the budget conversation trivial well past that. For a side project, a local business newsletter, or anyone whose list may never need to make money directly, that generosity is the whole decision.
MailerLite wins once the list becomes a business. Its paid tiers — especially Power — carry a monetization stack Sender doesn't match: paid newsletter subscriptions, digital product sales, plus landing pages and websites in the same account. Sender's tradeoff for its generous limits is a thinner feature ceiling; MailerLite's tradeoff is that its free tier is now essentially a trial. If you're weighing monetization platforms more broadly, the same logic drives our MailerLite vs GetResponse comparison — both are stronger picks than Sender for selling courses or paid content.
The honest verdict
If you want the most generous free plan available in 2026 and don't need monetization or a deep feature stack yet, Sender wins this one outright — the post-restructure numbers aren't close. If you plan to sell digital products or paid newsletter subscriptions as the list grows, MailerLite's paid Power plan is the better long-term home, and that's the tier to price, not the free one. Budget-focused senders comparing pricing models more broadly should also read MailerLite vs Brevo, where volume-based billing changes the math again.
Try Sender if free runway is the priority; MailerLite is the move if the monetization stack is. Both adjust plans and limits over time — verify current numbers on the official pricing pages before committing.
Frequently Asked Questions
Which free plan is more generous, MailerLite or Sender?
Sender, by a wide margin. Verified July 2026: Sender's free plan covers 2,500 subscribers and 15,000 emails a month, versus MailerLite's 250 subscribers and 2,500 emails after its mid-2026 restructure. That's ten times the subscribers and six times the sends.
Did MailerLite shrink its free plan in 2026?
Yes. Around June 2026, MailerLite renamed its paid plans to Comfort and Power, raised prices roughly 10–30%, and reduced the free tier to 250 subscribers and 2,500 emails a month. The earlier free plan — 1,000 subscribers and 12,000 emails — is gone, so older comparisons no longer apply.
Is Sender good enough to build a business on?
For growing and emailing a list, yes — and cheaply, with paid plans from $7/month. Where it runs out of road is monetization: if you plan to sell digital products or paid newsletter subscriptions, MailerLite's paid tiers carry those features natively and make the better long-term home.
