MailerLite Classic vs New MailerLite: What Actually Changed

MailerLite Classic was the older generation of MailerLite's product; the new MailerLite is the current one, and it's where MailerLite has moved its users, development and support. So the practical answer to the mailerlite classic vs new mailerlite question is: if you're signing up today, you get the new product — Classic is legacy, kept alive for accounts that were already on it. The differences that matter most are structural rather than cosmetic: the new product gives every paid plan the full feature set and scales price by list size and sending volume instead of gating features by tier.

Facts in this article were checked on 2026-10-25 against MailerLite's official pricing page and help docs. MailerLite changes plan details and migration policy from time to time, so confirm the specifics that affect your account — especially any Classic sunset dates and exact feature parity — on MailerLite's official documentation before you plan around them.

What actually changed

Plan structure: features stopped being the upsell

The biggest shift is how MailerLite sells. On the new product, every paid plan gets the full feature set — the variable is your list size and sending volume, not which features you've unlocked. That removes a whole category of upgrade decisions. You don't buy a higher tier to get automations; you move up when your list grows or you send more.

Power is positioned for volume and teams

MailerLite describes the Power plan as best for frequent senders, teams and AI agents. What that means concretely, per its pricing page: unlimited monthly emails, unlimited automations, unlimited forms, unlimited sites, unlimited digital products, unlimited user seats, unlimited templates, unlimited integrations, unlimited campaigns, multiple automation triggers, HeyLite intelligence, full MCP & API access, live chat and email support, exclusive partner discounts, and the ability to remove the MailerLite logo. If you're running an agency, a multi-seat team, or wiring MailerLite into an AI agent workflow, that's the tier designed for you.

Comfort covers the standard newsletter case

MailerLite positions Comfort as the plan for sending regular newsletters and running automations. It includes 50 automations, 10 forms, 10 sites, 5 digital products and email support. For a solo operator or a small team sending a weekly newsletter with a handful of welcome and re-engagement flows, that's the natural fit — 50 automations is generous for a typical newsletter setup.

Yearly billing and trials

Yearly billing saves 10% on MailerLite. Both Comfort and Power offer a free trial with no credit card required, which is the cheapest way to evaluate the current product against whatever you're using now.

Pricing compared

MailerLite's current model is structural: every paid plan gets the full feature set, and you pay more only for a bigger list or more sending. Yearly billing saves 10%. Both Comfort and Power come with a free trial that doesn't require a credit card.

We're not quoting specific amounts here because plan prices change and the only current number is the one on MailerLite's official pricing page. Open it, enter your actual contact count, and compare the monthly and yearly figures side by side — the 10% yearly saving is usually the difference between two plans' monthly costs.

If you're comparing MailerLite against other tools at the same time, it helps to know what each one charges for. Mailchimp, for example, offers a 14-day free trial of the Standard plan and lets customers cancel or downgrade to Essentials or the basic Free plan at any time, and its Standard plan allows sending up to 6,000 emails each month (verified 2026-10-25 on Mailchimp's pricing page). Brevo offers a free plan that is free forever and requires no credit card, and a yearly billing option with a 10% discount (verified 2026-10-25 on Brevo's pricing page). See MailerLite alternatives compared for the wider picture.

Where each option is strong

New MailerLite is strong on breadth per euro. Full feature set on every paid plan means you're never blocked from a capability by tier. Power's unlimited monthly emails, unlimited seats and unlimited automations make it a reasonable fit for agencies and teams that would otherwise pay per-seat elsewhere. HeyLite intelligence and full MCP & API access put it in the small group of email tools that officially support agent-driven workflows — Brevo, for instance, also offers MCP for ChatGPT & Claude (verified 2026-10-25 on Brevo's pricing page). The no-credit-card trial on Comfort and Power makes evaluation low-risk.

Classic's strength is continuity, not capability. If you're still on MailerLite Classic, your templates, forms and automations already exist and already work. There's real value in a setup you know, especially if your automations are load-bearing for revenue. That's the honest case for staying: not that Classic does something the new product can't, but that a working system has a cost to replace. MailerLite's development and support are focused on the current product, so weigh that against the migration effort.

Migration notes for remaining Classic users

If you've decided to move, do it in this order. It's the sequence that avoids the two classic mistakes: losing suppression data and breaking deliverability.

1. Export contacts and suppression lists first. Your suppression list is the part nobody remembers until after the switch. Export it alongside your subscriber data and keep both files until the migration is verified.
2. Inventory what you actually use. List your live templates, forms, landing pages and automations. Most accounts have a long tail of abandoned automations — you don't need to rebuild those.
3. Rebuild core automations first. Welcome series, abandoned cart, re-engagement. Get those three working before you touch anything else. If you're moving to a tool with an AI automation builder, describing the workflow in a sentence and reviewing the draft is faster than rebuilding node by node.
4. Re-verify your sending domain. DKIM, SPF and DMARC need to be set up on the new platform. Guided setup with automatic verification saves an afternoon of DNS debugging.
5. Test with a small segment. Send a real campaign to a small segment of your most engaged contacts before switching the whole list over.
6. Run both in parallel briefly. If your plan allows it, keep Classic live for a week while the new setup proves itself.

If you'd rather not do this by hand, Mailerflow offers free migration help on eligible paid plans covering contacts, suppression lists, templates and core automations. Its CSV import includes duplicate and validity checks plus custom fields and tags, which matters more than it sounds — duplicate contacts can inflate list counts after a move. MailerLite's own docs remain the authoritative source for Classic export steps.

Migration checklist
[ ] Export contacts + suppression list
[ ] List live templates, forms, pages, automations
[ ] Rebuild welcome / cart / re-engagement flows
[ ] Set up DKIM, SPF, DMARC on new domain
[ ] Test send to a small engaged segment
[ ] Run both platforms in parallel for one week
[ ] Retire Classic only after two clean sends

Which to choose

Choose new MailerLite if you want the current product, the full feature set on every paid plan, unlimited monthly emails and unlimited seats on Power, and official AI agent access through HeyLite and MCP. Stay on Classic only if you have a specific, confirmed reason to keep a working setup unchanged — and check with MailerLite first about what support and updates a Classic account still receives.

If you're migrating anyway, compare the destination before you commit. Mailerflow gives you unlimited emails on every paid plan, a Free plan with 2,500 contacts and 10,000 emails a month, paid plans from $14.90/month, and an AI email builder where you describe an email and get a complete responsive design plus subject lines and preview text. Open Mailerflow's pricing page in the same tab as MailerLite's and enter your contact count in both before you rebuild anything.

FAQ

Is MailerLite Classic still available?

Classic accounts have continued to function as a legacy product, but MailerLite's current development and support focus is the new product. Availability and any retirement timeline for Classic are policy decisions that change — check MailerLite's official docs for the current position on your account type.

Can I move my automations from Classic to the new MailerLite?

Automations generally need to be rebuilt rather than transferred, because the automation builder changed between generations. Rebuild your core flows first — welcome, cart recovery, re-engagement — and leave the long tail until you've confirmed the new setup performs. MailerLite's docs are the place to confirm whether any import path exists for your specific case.

Will my templates carry over?

Treat templates as something you'll recreate. Export any custom HTML you've written so you have the source, then rebuild the visual ones in the current editor. If you're moving to a different platform entirely, a migration service that covers templates removes this step — Mailerflow's free migration help on eligible paid plans includes templates.

Does the new MailerLite cost more?

It's structured differently rather than simply more expensive: every paid plan gets the full feature set, and price scales with list size and sending volume. Yearly billing saves 10%. Compare your actual contact count on MailerLite's official pricing page rather than comparing plan names.

What happens to my sending domain when I migrate?

You'll re-verify it on the new platform by adding DKIM, SPF and DMARC records. Keep the old records in place until the new ones verify, then send a test campaign to a small engaged segment before moving your full list. Skipping this step can cause a deliverability dip after a migration.
