Fix Mailchimp-Squarespace Integration Issues Fast

TL;DR: Key Points
  • Disconnect and reconnect your Mailchimp form block to resolve issues
  • Disable double opt-in in Mailchimp for instant subscriber additions
  • Check for and correct field mismatches and required fields in Mailchimp
  • Consider creating a new audience for cleaner data management
  • Enable Google reCAPTCHA to protect your forms from spam
  • Sometimes, the most efficient solution is to manually add problematic email addresses

Preparing Your Integration

Before you start using Mailchimp with Squarespace, make sure your form complies with Mailchimp's limit of 30 fields. This prevents submission errors from the start. Also, connect your audience to one form block only to keep data clean and organised properly. Using different blocks for the same audience will cause syncing errors or mismatches.

Fixing Email Submission Errors

Sometimes you'll get notifications about errors in email submissions. Here's how to handle this:
  1. In Squarespace, access the Pages panel and go to the page in question
  1. Double-click on the form or newsletter block to open the block editor
  1. Click on the Storage tab
  1. In the Mailchimp connection, first disconnect, then reconnect by selecting the appropriate audience from the drop-down
Pixelhaze Tip: Always test your form with an unused email address to verify the entire flow works smoothly and error-free.

Resolving Submission Sync Issues

If new subscribers aren't being added as expected or you're seeing sync discrepancies, try these adjustments:
  • Uncheck any required fields in your Mailchimp setup. Required fields can sometimes block a submission if they aren't filled out exactly as Mailchimp expects.
  • Switch to a fresh audience. Using a new, empty audience can simplify the integration and often fixes persistent issues quickly.
To reset your Mailchimp connection:
  1. Go to the page editor in Squarespace
  1. Double-click the form or newsletter block
  1. Click 'Disconnect' on the Mailchimp connection
  1. Log into Mailchimp, go to Integrations, manage 'Other connections', and disconnect Squarespace
  1. Reconnect in Squarespace to establish a new link

Handling Email Delivery Challenges

If subscribers aren't receiving their confirmation emails or if emails are ending up in spam folders, disable the double opt-in feature in Mailchimp. This skips the need for subscriber email confirmation. Also, be aware that emails might face tougher scrutiny under stricter DMARC policies from free email providers, such as Yahoo or AOL.

FAQs

How do I reconnect a form block with Mailchimp in Squarespace?

To reconnect a form block with Mailchimp in Squarespace, open the page editor, double-click the form block, click the Storage tab, and choose your desired audience from the drop-down menu after disconnecting the initial connection.

Why are my subscribers not receiving confirmation emails?

This issue is often due to the double opt-in feature in Mailchimp. Disabling this feature will automatically add subscribers to your audience without an email confirmation.

What should I do if new subscribers aren't being added to my Mailchimp audience?

First, try unchecking any required fields in your Mailchimp settings. If problems persist, consider connecting to a new, empty Mailchimp audience.
