TL;DR: Key Points

Implement basic practices to manage and mitigate spam

Squarespace forms and newsletter blocks sometimes break down, and it's usually more frustrating than it needs to be. The good news is that most issues follow predictable patterns, which means you can fix them systematically.

Let's start with the simplest solution that works about 60% of the time.

Basic Troubleshooting Steps

Try this first before anything else:

Remove the problematic form or newsletter block

Re-add the block to your page

Reconnect it to your chosen storage service

This often clears up initial glitches by refreshing the integration. If that doesn't work, you'll need to dig deeper.

Diagnostic Checklist for Common Errors

Problems usually happen at two stages: when visitors try to submit, or when the data should reach your storage service.

Visitor Submission Phase

These show up as error messages when people try to fill out your form:

Invalid Email Format: The most common culprit. Make sure the email follows standard "user@domain.com" format. No spaces, proper @ symbol, valid domain extension.

Storage Communication Errors: Your form can't talk to Google Drive, Mailchimp, or whatever service you've connected. Check the connection in your form settings.

Generic Errors: If you see "Unknown error, please try again later", this is often Squarespace's spam protection kicking in. Ask the user to try again in a few minutes.

Storage and Email Notification Issues

After someone submits successfully, the data should land where you expect it:

Data Not Reaching Storage Services: Double-check your connections with Squarespace mailing lists, Google Drive, or Mailchimp. These integrations break more often than they should.

Missing Email Notifications: Check your spam folder first. Then verify your notification email address in the form settings is correct and active.

Dealing with Spam and Storage Errors

Getting flooded with spam or seeing error notifications from your storage setup? Here's what to do:

For spam: Tighten your form settings. Turn on reCAPTCHA if you haven't already, and consider requiring phone number verification for high-value forms.

For storage errors: Follow the steps in any error emails you receive from Google Drive or Mailchimp. These usually involve re-authorising the connection.

Pro tip: When reconnecting services like Google Drive or Mailchimp, test with a backup email address that's not already in your audience lists. This prevents conflicts and shows you if the fix actually worked.

FAQs

How can I fix the error message "Email address not valid" in my Squarespace form block? Check that the visitor enters a correctly formatted email address following "user@domain.com" format.

Why am I not receiving form submission emails on my Squarespace website? Ensure your email system accepts emails from Squarespace's default addresses, and check your spam folder.

What should I do if I receive a "Form submission error" email related to Google Drive or Mailchimp? Follow the reset steps outlined in the error email to restore proper connectivity.

Jargon Buster

Form Block: A tool on Squarespace sites used to gather visitor information via custom forms

Wrapping Up

Most Squarespace form issues stem from broken connections between your site and storage services, or simple formatting problems with email addresses. Start with the quick fix of removing and re-adding your blocks. If that doesn't work, check your integrations and spam folders. Keep your form requirements simple and clear to avoid confusing visitors, and always test with a fresh email address when troubleshooting connections.
