Who this move suits
Moving makes sense when you can name what MailerLite does better for you, often price at your list size or its site builder, and you are prepared to rebuild sequences and forms by hand. Check plan fit first: MailerLite's pricing page lists Free at up to 250 subscribers and 2,500 emails a month, Comfort from $12 a month and Power from $25 a month, with a 14-day premium trial. If your Kit setup has many interlocking sequences, count the rebuild hours before you count the savings.
Mapping Kit to MailerLite
The left column is what you have in Kit; the right is where it lands in MailerLite and how it gets there. Only subscribers, fields and tags move by file. Everything else is a manual rebuild.
| Kit item | MailerLite equivalent | How it moves |
|---|---|---|
| Subscribers | Subscribers | CSV export from Kit, import in MailerLite |
| Tags | Groups | Tags column in the export; MailerLite can create groups from it at import |
| Custom fields | Custom fields | Included in the export; map or create fields during import |
| Segments | Segments | Rebuild the rules, or export a segment from Kit and import it to a group |
| Sequences and visual automations | Automations | Rebuild by hand in the Automation tab |
| Forms | Forms | Recreate in the Forms tab and replace embeds on your site |
| Landing pages | Sites, Landing pages | Recreate; check page limits on your plan |
| Email templates | My templates | Recreate in the drag and drop editor |
| Open and click history | Not listed in the export | Keep Kit reports if you need history |
Step 1: export from Kit
In Kit, open Subscribers, filter by status, tick the box at the top of the list and then click Select all. Kit's help says that if you skip Select all, only the current page is exported. Open the three-dot menu, choose Export, and wait for the email; large lists can take several minutes. Download within five days.
Kit lists these columns in the export: first name, email address, created date and time, status, tags, location, attribution data and custom fields. To move one segment separately, open the segment, select all, and export it the same way. Keep the original files unedited as a backup and work on a copy.
Step 2: decide who to import, then import
MailerLite's Kit guide says to bring only subscribers who opted in, and to leave out unsubscribed contacts, people who marked email as spam, and inactive subscribers. Filter the status column in your copy before upload.
In MailerLite, go to Subscribers, Add subscribers, and upload the CSV saved as UTF-8. Map each column, create any missing custom fields, and assign a group. When MailerLite asks about Tags or Groups columns, choose whether to create groups from them, then match and save. Decide whether blank cells should overwrite existing data. MailerLite also rejects role-based addresses such as admin@ and support@, so expect a small failed count.
Step 3: rebuild sequences without restarting them
MailerLite's import lets you choose whether newly imported subscribers trigger automations linked to a group. For a migration, that choice decides whether 3,000 existing readers receive email one of your welcome series on the same day. Leave it off for the bulk import of existing readers.
Rebuild each Kit sequence as a MailerLite automation, triggered by joining a dedicated group for new signups only. Test with addresses you control: a new signup should enter, an imported existing subscriber should not. Our guide to importing without restarting a welcome series covers the same problem from the Kit side.
Step 4: forms, domain and testing
Recreate forms and landing pages, then replace the Kit embeds on your site. Authenticate your sending domain before your first campaign; MailerLite's guide says this helps avoid spam issues. Preview forms, send test emails to yourself, and trigger each automation once before switching traffic.
Cutover checklist
- Pause new sequence entries in Kit before the final export so nobody is mid-sequence in both tools.
- Export with Select all and confirm the row count matches Kit's subscriber total for that status.
- Save unsubscribed and complained addresses from Kit as a suppression file outside both tools.
- Import with automation triggers off; confirm group counts match tag counts.
- Switch forms on your site to MailerLite, then run a final Kit export of anyone who joined during the switch.
- Send one campaign to a small engaged group first and check complaints and bounces before the full list.
- Keep the Kit account until the first MailerLite campaign and automation have worked.

Watch on YouTubeQuestions before you decide
Do Kit tags come across to MailerLite?
Kit's export includes a Tags column, and MailerLite's import says that when a file has Tags or Groups columns you can choose whether it creates new groups from them.
Do Kit sequences import automatically?
No. MailerLite's Kit migration guide says to rebuild automated flows in its Automation tab, either from scratch or from a template.
How long is the Kit export link valid?
Kit says export links expire after five days, and the link is emailed to the account address, with team members' exports also going to the account owner.
Will MailerLite import my unsubscribed contacts?
Its import page lists addresses already unsubscribed or labeled bounced, unconfirmed or spam complaint among those that fail to import. MailerLite also advises leaving unsubscribed, spam-complaint and inactive contacts behind, so keep your Kit export as your suppression record.
