MailerLite is a simple, affordable alternative for businesses that were primarily using HubSpot for basic email marketing. If you never fully used HubSpot's CRM and automation features, MailerLite covers the essentials at a much lower price.
This guide covers everything you need to migrate from HubSpot to MailerLite without losing subscribers or breaking your automations. Estimated time: half a day.
What transfers and what does not
| Item | Transfers? | Notes |
|---|---|---|
| Contacts and email addresses | Yes | Via CSV export/import |
| Tags and segments | Partial | Export as custom fields, remap on import |
| Custom field data | Partial | Transfers if mapped correctly during import |
| Unsubscribe history | Yes | Import as suppressed contacts |
| Email templates | No | Need to be rebuilt in MailerLite |
| Automation workflows | No | Need to be rebuilt from scratch |
| Campaign history | No | Historical stats stay in HubSpot |
| CRM/deal data | No | MailerLite does not have a built-in CRM |
HubSpot has a built-in CRM. MailerLite does not. Deal data, pipeline stages, and sales notes cannot be migrated. If you rely on HubSpot's CRM, you will need a separate CRM solution after the switch.
Step-by-step migration guide
Sign up at www.mailerlite.com before doing anything else. Keep your HubSpot account running throughout the migration: do not cancel it until everything is confirmed working in MailerLite.
Add your domain to MailerLite and follow the DKIM authentication instructions. This improves deliverability and ensures your emails arrive in inboxes, not spam folders. Complete this before importing any contacts.
In HubSpot, go to your audience and export your full contact list as a CSV. Make sure to include all custom fields, tags, and segments. Export your unsubscribed contacts separately: you will need to suppress these in MailerLite to stay compliant.
Upload your CSV into MailerLite and map each column to the correct field. Import your unsubscribed contacts as suppressed. Review the import report carefully before proceeding: fix any mapping errors before building automations.
Screenshot or document all your active automations in HubSpot before rebuilding them in MailerLite. Start with your highest-priority flows: typically your welcome series and any active nurture sequences. Do not activate them until you have tested them with your own email address.
Build your signup forms in MailerLite and replace the HubSpot embed codes on your website. Test each form to confirm subscribers land in the right list and trigger the correct automation.
Send a test campaign to yourself. Trigger your automations manually. Check every link. Confirm your unsubscribe flow works correctly. Only cancel HubSpot once you are fully satisfied that MailerLite is working as expected.
Once MailerLite is fully operational, cancel your HubSpot account. Check your billing date to avoid being charged for another month. Download any historical reports or data you want to keep before cancelling.
The bottom line
MailerLite makes sense if you were using HubSpot mainly for email newsletters and basic automations. You will lose CRM, advanced reporting, and automation depth, but if you were not using those features, the cost savings are significant.
