HubSpot and Mailchimp integration

HubSpot holds the contact data, Mailchimp sends the campaigns, and there is one list rather than two. Contact lists, segments and campaign results stay in step on their own. A marketer builds a Mailchimp campaign on behavioural data from HubSpot without moving anything by hand.

Why companies connect HubSpot to Mailchimp

Anyone running HubSpot and Mailchimp together ends up reconciling contact lists manually. The two drift apart, campaigns go out to segments that are out of date, and an unsubscribe has to be honoured twice.

How we do it

A two-way sync keeps contact data and subscription consent in one version. Campaign results from Mailchimp are written back onto the contact in the HubSpot CRM.

Frequently asked questions

Does this replace HubSpot's own email marketing?

No. The integration is a bridge between the two: you can use HubSpot's email tools and Mailchimp's, and the data stays in step. It makes sense for companies already established on Mailchimp who do not want to leave it.

How are subscription preferences and consent handled?

Unsubscribes and marketing consent sync both ways. If a contact unsubscribes from a Mailchimp list, their subscription status updates in HubSpot as well, and the other way round - which is what the GDPR requires of you.

Which HubSpot segments can be synced to Mailchimp?

Any static or active list can be mapped to a Mailchimp list, including segments built on lifecycle stage, lead score, original source, contact properties and activity history.
