Integrating Mailchimp with Zoho CRM links your marketing lists and campaign data to the CRM so sales and marketing share the same contact view, campaign history, and audience segments. The connection reduces manual exports, keeps subscription status in sync, and surfaces campaign engagement inside contact records.
What is it
The Mailchimp integration for Zoho CRM synchronizes Mailchimp audiences and campaign activity with Zoho CRM records so you can see who received or engaged with campaigns from inside CRM and create CRM-based audience segments for Mailchimp sending [1] [5]. It passes subscriber status (subscribed, unsubscribed) and campaign metrics back to contact and lead records so sales reps get campaign context without switching tools [2]. The integration also supports sending campaign data into CRM feeds and automating list syncs on a schedule or via field-based triggers [1].
When to use it
- You run email campaigns in Mailchimp but want campaign opens, clicks, and send history visible on contact or lead records in Zoho CRM so sales can follow up with engaged prospects [1].
- You want to keep subscription status synchronized between Mailchimp and Zoho CRM to prevent sending emails to unsubscribed contacts and to maintain a single source of truth for consent [1].
- Your marketing team builds Mailchimp audiences from CRM data (segments, custom fields) and needs that audience updated automatically when CRM records change [1] [2].
- You need a simple way for support or sales agents to see which campaigns a customer received and the campaign status without leaving Zoho products (for example, viewing Mailchimp campaign info inside Desk or CRM) [7].
- You are preparing for deliverability work and will authenticate sending domains or check sender settings in your broader Zoho marketing stack (useful when moving recipients between Zoho Campaigns, Mailchimp, and CRM) [3].
How to access it
In Zoho CRM: open Setup > Marketplace > All Extensions and search for "Mailchimp" to install the Mailchimp extension; after installation go to Setup > Extensions > Mailchimp to configure list sync and field mapping [5] [1]. In Mailchimp: generate an API key under Account > Extras > API keys and paste it into the Mailchimp extension settings in CRM to authorize the connection [1]. For programmatic control use Mailchimp’s API to manage audiences and Zoho CRM’s REST API (Contacts/Leads modules) to read/write subscriber fields if you need a custom connector or two-way automation [2] [5].
