When Google Forms and Mailchimp operate independently, data entry teams often face the challenge of manually transferring form responses into Mailchimp lists. For instance, if a Google Form collects subscriber information but does not integrate with Mailchimp, team members must copy each entry, including names and email addresses, into Mailchimp, which is time-consuming and prone to human error. This manual process can lead to missing entries or incorrect data, resulting in ineffective marketing campaigns and wasted resources.

Top Ways to Automate Google Forms & Mailchimp

  • Seamless Data Transfer: Automatically sync responses from Google Forms directly to your Mailchimp audience lists, ensuring your marketing database is always up-to-date without manual intervention.
  • Targeted Campaigns: Create automated workflows that segment your audience based on form responses, allowing you to send personalized email campaigns tailored to specific interests and needs.
  • Real-Time Analytics: Gain immediate insights into form submissions and campaign performance by integrating analytics from both platforms, enabling data-driven decision-making and improved marketing strategies.

How to Build the Google Forms → Mailchimp Sync

  1. Set up a Google Form to collect subscriber information, ensuring fields for 'Email', 'First Name', and 'Last Name' are included.
  2. In Google Forms, navigate to the 'Responses' tab and click on the three dots to access the 'Get pre-filled link' option. This will be used to create a webhook.
  3. Use the Google Apps Script editor to create a new script. Write a function that triggers on form submission, listening to the 'onFormSubmit' event.
  4. Within the script, extract the payload data using e.values to get the form responses.
  5. Construct a JSON object with the extracted data: { 'email_address': e.values[1], 'merge_fields': { 'FNAME': e.values[2], 'LNAME': e.values[3] } }.
  6. Make a POST request to the Mailchimp API endpoint https://.api.mailchimp.com/3.0/lists//members, where is your data center and is your Mailchimp list ID.
  7. Include your Mailchimp API key in the request header for authentication.
  8. Test the integration by submitting a response in the Google Form and checking the Mailchimp list for the new entry.

Developer Warnings & API Gotchas

  • Ensure that the email address field in Google Forms matches the Mailchimp required format; otherwise, the API will reject the entry.
  • Be cautious with the merge fields in Mailchimp; if the field names in the JSON object do not match the Mailchimp audience settings, the data will not populate correctly.
  • Remember that Mailchimp requires email addresses to be unique; if a duplicate entry is submitted from Google Forms, it will cause an error in the API response.
