When Zoho CRM and Mailchimp operate independently, lead data can become fragmented. For instance, if a sales representative updates a lead's status in Zoho CRM, that change may not reflect in Mailchimp, leading to marketing campaigns being sent to leads that are no longer active. This results in wasted marketing resources and time spent by the marketing team manually checking and updating lead statuses, which could be better spent on strategic initiatives.

How to Build the Zoho CRM → Mailchimp Sync

  1. In Zoho CRM, set up a webhook to trigger on lead status updates. Use the endpoint https://your-zoho-domain.com/webhooks/leads/update.
  2. Configure the webhook to send a payload containing the lead's id, email, and status to your server.
  3. On your server, listen for incoming webhook requests and extract the relevant data from the payload.
  4. Once you have the lead's id, email, and status, construct a POST request to Mailchimp's API endpoint https://.api.mailchimp.com/3.0/lists//members.
  5. In the POST request, include the extracted email and the updated status in the payload as follows:
