| Option | Direction | What starts it | Best for | Watch out for |
|---|---|---|---|---|
| Letaido AI agent | HubSpot leads into Mailchimp, or Mailchimp signups and clicks into HubSpot | A schedule, a Mailchimp audience event, or when you ask | Tagging form leads by the form they used, swapping tags for new customers, turning email clicks into notes and owner tasks | Doesn't mirror every field change: each job runs at its set time, on a Mailchimp audience event, or on request |
| HubSpot's Mailchimp integration | HubSpot to Mailchimp for contacts, Mailchimp email activity back to HubSpot | A non-HubSpot form submission, plus an activity check every 15 minutes | Adding people from non-HubSpot forms to a Mailchimp list and seeing sends, opens, clicks and bounces on HubSpot contacts | Only sends first name, last name and email, and can't sync to a list with required merge tags. Campaigns in A/B tests or Customer Journeys are not synced |
| HubSpot data sync for Mailchimp | One way or both ways, field by field | Record changes, synced within about 10 minutes | Keeping contacts matched in both apps | Custom field mappings need a paid Data Hub subscription. Syncs mapped fields using configured rules rather than running multi-step jobs |
| Zapier | Either way | A HubSpot or Mailchimp event | Templates like new HubSpot contacts added to a Mailchimp list, or new Mailchimp subscribers sent to HubSpot, one recipe per direction | Most HubSpot triggers are checked on a timer instead of firing on each change, and each successful action step counts as a task |
HubSpot and Mailchimp: the old way vs. Letaido
- 1Export new form fills
- 2Remove the opt-outs
- 3Import the CSV to Mailchimp
- 4Map names and tags
- 5Repeat every week
Every hour, find HubSpot contacts who filled in a form in the past hour and add them to my Mailchimp audience 'Newsletter' as pending, so Mailchimp sends its confirmation email. Fill in first and last name and tag them 'HubSpot' plus the form name. Skip anyone unsubscribed in HubSpot. If they are already in the audience, only add the tags.

Frequently asked
Does HubSpot integrate with Mailchimp? +
Yes. HubSpot's own apps copy contacts and email activity between the two. Letaido's AI agent, Leta, works with both in one job for the parts that need a decision, like which tag a lead gets or which click is worth a sales task.
How do I connect HubSpot and Mailchimp to Letaido? +
Link HubSpot and connect Mailchimp once. Then type the job in a chat, or copy a prompt from one of the jobs above.
Is it a two-way sync? +
No. Each job runs at its set time, on a Mailchimp audience event, or on request, so it doesn't mirror every field change. HubSpot's own Mailchimp apps can keep copying contacts and email activity alongside it.
Can a new Mailchimp subscriber start a job? +
Yes. A new subscriber in your audience makes Leta find or create the HubSpot contact and add a note. An unsubscribe or cleaned address sets a Mailchimp status property and adds a note; create that contact property in HubSpot once first. Letaido registers the audience webhook in Mailchimp for you, so there is no URL to paste.
Will new HubSpot leads get Mailchimp's confirmation email? +
Yes. The form leads job adds new people as pending, so Mailchimp sends its confirmation email first. Contacts who opted out in HubSpot are skipped, and people already in the audience keep their subscription status.
Can Zapier connect HubSpot and Mailchimp? +
Yes, with one recipe per direction. Most of its HubSpot triggers are checked on a timer, and each successful action step counts as a task. With Leta you describe the whole job once, and it can sort the data as it goes, like picking out pricing page clicks for the contact owner.
Will it ask before it changes HubSpot or Mailchimp? +
Allow all read operations once per app; approve each kind of write once.
