Bottom line up frontby Bill Belcamino, founder of HelpCompare
Editorial assessment

Bottom line up front: What should you clean up before importing a Mailchimp list into beehiiv?

Import only people who still want your email, and keep their original signup dates, because beehiiv makes each subscriber's import date their subscription date by default.

The move itself is well documented: a CSV import for subscribers, a content importer that pulls past posts in 5 to 15 minutes, and it works on the free Launch plan up to 2,500 subscribers. Automations, templates and legacy-builder campaigns don't come across. My advice: leave unsubscribed and bounced addresses out of the upload, and map the original signup date to its own field when you match columns. Otherwise every reader looks brand new, and any rule you set later to spot people who've gone quiet has nothing real to measure against. Rebuild the welcome automation before your first beehiiv send, because anyone who signs up in the gap gets nothing.

    Why teams move from Mailchimp to beehiiv

    Free up to 2,500

    beehiiv Launch is $0 up to 2,500 subscribers with unlimited sends.

    Pay for active subscribers only

    Unsubscribed and inactive subscribers do not count.

    Cheaper at scale

    Scale is $96 a month billed annually at 10,000 against Mailchimp Essentials at $110.

    How the migration actually works

    Campaigns made with Mailchimp’s Legacy Email Builder are not imported, and by default each subscriber’s import date becomes their subscription date.

    StepWhat you do
    1Export your audienceIn Mailchimp, export contacts from your audience as a CSV.
    2Import subscribersIn beehiiv, go to Settings > Subscribers Import, upload the CSV and match columns to beehiiv fields.
    3Import past postsIn beehiiv’s content importer choose Mailchimp and click Connect to authenticate; it takes 5 to 15 minutes depending on the number of posts.
    4Set a default post styleRecreate your template as a default post style.
    5Rebuild automationsRecreate Mailchimp automations with beehiiv Automations.
    6Pick a planStay on Launch up to 2,500 subscribers, or choose Scale or Max as you grow.
    7Switch sending and cancelSend your first issue from beehiiv, then downgrade Mailchimp.

    What this path doesn’t do for you:

    Automations, templates and legacy-builder campaigns do not come across, and original signup dates are replaced by the import date by default.
