The Free Mailchimp–Salesforce Connector Is Gone. Here's What Replaced It.
Mailchimp de-listed its free Salesforce connector in 2024. If you're a small nonprofit syncing email and giving data, here are the real options and what to map.
A small nonprofit wants the obvious thing. When someone gives or signs up in Salesforce, they should land on the right Mailchimp audience. When someone unsubscribes in Mailchimp, Salesforce should know so you stop emailing them. For years the answer was easy: install Mailchimp’s own free “Mailchimp for Salesforce” app from the AppExchange and wire it up.
Then it quietly went away. Teams usually find out the hard way — they go to install it and it isn’t there, or the copy they’ve had for years stops syncing and there’s no support behind it.
What actually happened
Mailchimp de-listed and retired its own free Salesforce connector around the end of May 2024. It’s unsupported and being wound down. The integration Mailchimp now points to as official is built by Beaufort 12 — confusingly, also named “Mailchimp for Salesforce” on the AppExchange. It’s a paid, subscription product; Mailchimp handed it the “official” mantle.
So if you’re standing this up in 2026, the free first-party option no longer exists. Here’s the honest field for a small org:
- Mailchimp for Salesforce by Beaufort 12 — the official paid package, with a low-cost entry tier. The most complete and native option.
- SyncApps by Cazoomi — has a limited free tier and paid plans above it; long popular with nonprofits.
- Zapier / Make — glue for simple “new Salesforce contact → add to a Mailchimp audience” flows. Cheap and flexible, but you own the logic, and two-way sync (especially unsubscribes) gets fiddly fast.
- Salesforce Marketing Cloud / Account Engagement — the native Salesforce email platforms. For a small nonprofit, almost always overkill and over budget; worth naming mainly to rule out.
The tool is the easy 20%. The mapping is the 80%.
Which connector you pick matters less than the decisions underneath it — and this is where most “the sync is messy” problems actually come from:
- Pick a direction. Most small orgs want one-way, Salesforce → Mailchimp: Salesforce is the source of truth for who exists, Mailchimp is the send tool. Full two-way sync invites conflicts over who wins when both sides change a record. Decide deliberately; don’t let the default decide.
- Segment with tags/groups. The payoff isn’t “the same names in both systems” — it’s pushing a giving segment (donor / lapsed / monthly / event attendee) from Salesforce into Mailchimp as a tag, so your email targeting reflects how people actually give.
- Unsubscribe is the one field you cannot get wrong. When someone opts out
in Mailchimp, that must write back to Salesforce (
HasOptedOutOfEmail/ Email Opt Out). If it doesn’t, you’ll keep emailing people who told you to stop — a trust problem and a compliance problem. Verify the unsubscribe path maps both ways, or at minimum Mailchimp → Salesforce, before you trust it. - Watch the WordPress overlap. Plenty of nonprofits also run GiveWP or a form plugin that pushes straight to Mailchimp (“send donation data to Mailchimp”). Now two systems write to the same audience, double-subscribe contacts, and fight over fields. Pick one writer per audience.
The connector you choose is a checkbox. The data model — direction, segments, and a bulletproof unsubscribe path — is what decides whether the integration quietly helps your fundraising or quietly emails the wrong people.
