You already liked the simplicity. Keep it, pay less.
MailerLite is a well-built, well-priced tool, and this is a closer contest than most on this page. The move makes sense when your list has grown past the point where paying by subscriber still feels fair.
10,000 subscribers, 40,000 emails/month · Typical migration: 1–2 days of work
MailerLite migrations are straightforward: subscribers, fields and groups export cleanly, and automations are simple enough to rebuild in an hour or two. The reason to move is list size. MailerLite bills by subscriber, so a 10,000-subscriber list is around $89 a month regardless of whether you email weekly or monthly; the same list emailed weekly is 40,000 sends, which is $30 on Bluey Grow. Below a few thousand subscribers the gap is small and MailerLite is a perfectly good tool — this migration is worth doing once your list is large relative to how often you send it.
What transfers, and what you rebuild
Stated up front, because finding out mid-migration is how a two-day job becomes a two-week one.
| What | Status | Detail |
|---|---|---|
| Subscribers & fields | Transfers | Clean CSV export including custom fields. |
| Groups & segments | Transfers | Groups export as membership and become Bluey segments. |
| Unsubscribes & bounces | Transfers | Export separately and import before subscribers. |
| Automations | Rebuild | Usually simple on MailerLite — an hour or two to recreate. |
| Email templates | Partial | Export HTML and import; MailerLite templates are clean and usually port well. |
| Forms & popups | Rebuild | Rebuild in Bluey and update the embed code. |
| Landing pages | Rebuild | Rebuild in Bluey, or keep them where they are and point forms at Bluey. |
| Websites built in MailerLite | Rebuild | No equivalent. If you use MailerLite's website builder, that content needs a new home. |
The migration plan, in order
- 1Day 1 — before any sendAuthenticate your sending domainPublish SPF, DKIM and, if you use one, DMARC records for the domain you will send from. Gmail and Yahoo have required authentication and one-click unsubscribe from bulk senders since February 2024, and an unauthenticated first send from a new platform is the fastest route to the spam folder. This is a DNS change and takes about fifteen minutes; allow up to a few hours for propagation.
- 2Day 1Export subscribers, fields, groups and unsubscribesMailerLite's export is clean and well structured. Export unsubscribes and bounces separately, and import those into Bluey before subscribers.
- 3Day 1Rebuild automations and formsMailerLite automations are typically simple — a welcome sequence and perhaps one re-engagement flow — so this is usually under two hours. Rebuild forms and popups in Bluey and swap the embed code on your site.
- 4Day 1–2Port templatesMailerLite's templates are clean HTML and generally import into Bluey's composer without much fuss. Send a test and check mobile rendering.
- 5Week 1–2Run Bluey and MailerLite in parallelSplit the audience rather than duplicating it: send to one segment from Bluey and leave the rest on MailerLite. You get a like-for-like comparison of delivery, engagement and cost on your own data, and nobody receives the same campaign twice. Do not run both against the same contacts — that is the one way to make a careful migration look sloppy to your readers.
- 6Week 2 — graduallyRamp volume rather than switching itStart with your most engaged segment — people who opened or clicked in the last 30 days — and increase volume over several days. Receiving servers judge a new sending pattern partly on engagement, so leading with your best contacts builds reputation, while leading with your whole list including two-year-dormant addresses damages it. If you were on a dedicated IP, treat the new one as cold and warm it deliberately.
- 7Week 2Rehome anything built on MailerLite's website builderIf you used MailerLite to host a site or landing pages, that content needs somewhere else to live before you cancel. Bluey hosts landing pages but is not a website builder.

Migration FAQ
Is it worth switching from MailerLite?
It depends on your list size relative to your sending frequency, and the honest answer is sometimes not. At 10,000 subscribers emailed weekly, MailerLite is around $89 a month against $30 on Bluey — a clear gap. At 1,000 subscribers, the difference is small enough that the migration effort is hard to justify. Do the arithmetic on your own numbers before you start.
How long does it take?
One to two days for most accounts. MailerLite exports cleanly and its automations are usually simple, so there is far less to rebuild than on a mature ActiveCampaign or Klaviyo account.
What do I gain besides price?
A built-in CRM, transactional email on the same account, behavioural targeting, an AI campaign builder and email verification — none of which MailerLite offers. If you only need a newsletter sender, that breadth is not worth much; if you are already paying for a second tool to cover one of those gaps, it is.
Will my templates and forms come across?
Templates export as HTML and import into Bluey's composer, and MailerLite's markup is clean so they usually port well. Forms are rebuilt, which takes minutes, and you will need to swap the embed code on your site.
What about my MailerLite website?
It does not move. Bluey hosts landing pages but is not a website builder, so if you have real pages on MailerLite's site builder, rehome them somewhere else before you cancel the account.
