Keep Salesforce and Mailchimp in sync, automatically, both ways.
SyncMailChimp connects Contacts, subscriptions, and tags between Salesforce and Mailchimp, and puts a live Mailchimp panel right on the Contact record — so no one re-keys a subscriber, misses an unsubscribe, or logs into Mailchimp just to check a tag.
Live in 3–5 business days · Works with any Mailchimp plan with API access · Full-time support included
One tile, five jobs, zero manual re-entry
Everything below runs on Salesforce automation and the Mailchimp API — no spreadsheets, no manual exports, no double data entry between your CRM and your audience.
New Contact → Mailchimp
The moment a Contact is created (or meets your criteria) in Salesforce, they're added to the right Mailchimp audience automatically.
Email & SMS subscription sync
Whichever channel a Contact opts into in Salesforce, email, SMS, or both, is set as their subscription status in Mailchimp.
Salesforce tags → Mailchimp
Tags and segment membership on the Salesforce Contact are pushed onto the matching Mailchimp audience member, so campaigns can target on them.
Mailchimp changes → Salesforce
Subscribes, unsubscribes, and status changes made in Mailchimp flow back into the Contact record within minutes.
Bidirectional, not one-way
Both systems stay the source of truth for what they're best at — Salesforce for the relationship, Mailchimp for the send.
A live Mailchimp panel, right on the Contact
A Lightning Web Component on the Contact page shows that person's Mailchimp status, tags, and recent activity — a read view pulled straight from Mailchimp, so your team never has to open a second tab to check it.
The full sync, in one picture
Salesforce owns the relationship data and pushes it out; Mailchimp owns delivery and reports engagement back in. The Lightning component reads Mailchimp live, without storing a copy in Salesforce.
Maroon = Salesforce → Mailchimp · Yellow = Mailchimp → Salesforce · Dashed = live read by the Lightning component
One flat price. No subscription.

Questions, answered
What exactly syncs between Salesforce and Mailchimp?
Five things, out of the box: new Salesforce Contacts get added to Mailchimp, email and SMS subscription status flows into the right audience, Salesforce tags/segments get pushed onto the matching Mailchimp member, Mailchimp subscribe/unsubscribe events flow back into Salesforce, and a Lightning component on the Contact page shows that member's live Mailchimp data.
Is the sync really two-way?
Yes. Salesforce pushes new contacts, subscriptions, and tags out to Mailchimp, and Mailchimp pushes subscribe and unsubscribe events back into Salesforce, so both systems stay accurate without anyone updating two places by hand.
Does this handle SMS subscriptions, or only email?
Both. Whichever channel a contact opts into in Salesforce, email, SMS, or both, is reflected as the matching subscription status on their Mailchimp audience member.
What happens in Salesforce when someone unsubscribes in Mailchimp?
Mailchimp sends the event to Salesforce automatically, and the Contact's subscription status is updated within minutes, so your sales and support teams never email someone who has opted out.
What does the Contact-page Mailchimp component actually show?
A lightweight Lightning component embedded directly on the Contact record that displays that person's live Mailchimp status, tags, and recent activity, without anyone leaving Salesforce or logging into Mailchimp separately.
Which Mailchimp and Salesforce editions does this work with?
It works with any Mailchimp plan that exposes API access, Essentials and above, and any Salesforce edition that supports Flow and Lightning components, including Sales Cloud, Service Cloud, Nonprofit Cloud, and NPSP orgs.
How long does setup take?
Most orgs are live within 3 to 5 business days: connecting the accounts, mapping fields and tags to your existing audience, and confirming the sync in a sandbox before it goes live.
Is $1,000 really the total cost?
Yes, $1,000 is a one-time setup fee that covers the full build: contact sync, subscription sync, tag sync, unsubscribe sync, and the Lightning component, plus ongoing support to keep it running as your Salesforce org and Mailchimp audience evolve.
What's included in the ongoing support?
We monitor the sync, fix failures, and adjust field or tag mappings as your Contact fields, record types, or Mailchimp audiences change, so the integration keeps working without you needing an admin dedicated to it.
