When Mailchimp and Keap operate independently, leads generated from marketing campaigns often go untracked in the CRM. For instance, if a new subscriber signs up via a Mailchimp form, that data must be manually entered into Keap, leading to potential errors such as incorrect email addresses or missed lead assignments. This manual entry wastes valuable time for the sales team, who could be focusing on follow-ups instead of data entry, ultimately delaying the sales cycle and impacting revenue.

Top Ways to Automate Mailchimp & Keap

Automated Lead Nurturing: Automatically transfer new leads from Keap to Mailchimp, triggering targeted email campaigns that nurture prospects based on their behavior and interests.
Real-Time Customer Updates: Ensure that customer information is always up-to-date by syncing changes made in Keap directly to Mailchimp, allowing for more personalized and relevant marketing efforts.
Streamlined Campaign Performance Tracking: Integrate campaign results from Mailchimp back into Keap, enabling comprehensive analysis of customer interactions and improving future marketing strategies.

How to Build the Mailchimp → Keap Sync

In Mailchimp, navigate to the 'Account' settings and select 'Webhooks'. Create a new webhook that listens to the 'Subscribe' event for your audience.
Set the webhook URL to point to your server endpoint that will handle incoming data, such as https://yourserver.com/mailchimp-webhook.
In your server code, extract the payload data from the webhook, specifically the subscriber's email address, first name, and last name from the JSON payload.
Use the Keap REST API to insert this data. Construct a POST request to https://api.keap.com/v1/contacts with the extracted data formatted as JSON in the body, ensuring to include the necessary authentication headers.
Test the integration by subscribing a new email in Mailchimp and verifying that the contact appears in Keap with the correct details.

Developer Warnings & API Gotchas

Ensure that the email address is validated before sending it to Keap, as duplicates can cause the API to return errors.
Be cautious with the data types; Keap requires specific formats for fields like phone numbers, which must be formatted correctly to avoid API rejection.
Monitor the payload size from Mailchimp; if it exceeds the limits set by your server, it may lead to incomplete data being processed.
