Mailchimp
Salesforce integration.
Who runs the Mailchimp Salesforce integration today, what it syncs, and how the older Mailchimp for Salesforce app differs.
The Mailchimp Salesforce integration for new set-ups is Salesforce Integration by Beaufort 12, listed on Mailchimp's site. It gives bi-directional sync, maps Salesforce data to Mailchimp and shows email activity on Salesforce leads and contacts. Mailchimp lists it from $25 USD a month per Salesforce org. Older Mailchimp for Salesforce set-ups follow separate help articles.
How it works
Does Mailchimp still have its own Salesforce integration?
Mailchimp's help articles for Mailchimp for Salesforce cover integrations set up before 1 May 2024. For set-ups on or after that date, Mailchimp points to the support options for Salesforce Integration by Beaufort 12.
The connector
Mailchimp audiences, Salesforce records.
Techila Global Services is a Salesforce Summit Partner. We help teams decide how Mailchimp and Salesforce should share data, set up the app, map fields and opt-outs, and test that email activity lands on the right records.
If you have outgrown Mailchimp, we also scope a move to Salesforce's own marketing products.
Which Mailchimp Salesforce app should you use?
There are two apps with similar names. Which help article applies depends on when your integration was set up.
| Option | What it syncs | Notes from the vendor pages |
|---|---|---|
| Salesforce Integration by Beaufort 12 | Bi-directional sync; maps Salesforce data to Mailchimp; email activity on leads and contacts; works with any Salesforce object | Listed on Mailchimp's site; from $25 USD a month per Salesforce org; support from Beaufort 12 |
| Mailchimp for Salesforce (set up before 1 May 2024) | Leads, contacts and campaign members pushed to an audience by Query Builder; subscriber and campaign activity on page layouts | Mailchimp's help articles cover these older integrations only |
| Custom API work or middleware | Flows the apps do not cover | You own the build, mapping and monitoring |
What moves between Salesforce and Mailchimp?
- Salesforce data mapped to Mailchimp (from Salesforce to Mailchimp)
- Email activity on leads and contacts (from Mailchimp to Salesforce)
- Unsubscribes made from Salesforce (from Salesforce to Mailchimp)
Our Salesforce integration services cover choosing and setting up either route.
How are unsubscribes and opt-outs handled?
- Beaufort 12 app: Mailchimp's listing says users can unsubscribe Salesforce contacts or leads from the app.
- Older Query Builder: contacts and leads with Email Opt-Out checked are left out of query results.
- Later opt-outs in the older app: if someone opts out in Salesforce after being added, Mailchimp says they won't be unsubscribed in Mailchimp. Plan a process for that gap.
- Disconnecting the older app does not affect subscriber data stored in Mailchimp.
What should you plan before connecting Mailchimp and Salesforce?
- Decide which Salesforce records become Mailchimp audience members: leads, contacts, campaign members or other objects.
- Choose which system owns email consent, and how an opt-out in one reaches the other.
- Agree which Mailchimp activity reps need to see on the Salesforce record.
- Test with a small audience in a Salesforce sandbox before syncing everyone.
