Mailchimp to HubSpot migration

MailchimpHubSpot Marketing Hub

Short answer

Moving from Mailchimp to HubSpot brings audiences, tags, consent status and templates into HubSpot contacts, lists and subscription types, so marketing email runs on the same platform as the CRM, with automation and reporting tied to pipeline.

Why firms make this move

Mailchimp works well for newsletters, but firms that want lead scoring, automation tied to CRM data and revenue reporting usually consolidate on HubSpot. Running both side by side often causes opt-out mismatches, so a clean switch is safer.

What moves

  • Audiences and contacts
  • Tags and groups as properties or lists
  • Unsubscribes and cleaned addresses
  • Templates rebuilt in HubSpot

Should we keep Mailchimp running?
