Preventing Form and Newsletter Block spam

Use this guide to reduce spammy messages sent through your site's Form Blocks. Although there's no way to block all spam from reaching you, there are a few strategies to decrease the amount. You may also want to read more about how to spot a phishing scam.

Why is this happening?

Spambots crawl the web looking for ways to share unsolicited content. They look for email addresses, forums, and contact forms. So, if you have a Form Block on your site, there's a chance you'll receive spam.

Reduce spam using Google reCAPTCHA

The best way to prevent spammy messages through your forms is to add Google reCAPTCHA. Google reCAPTCHA is a tool that distinguishes humans from spambots. It prompts visitors to check a box verifying that they’re not a robot, and sometimes asks visitors to complete another task, like identify a string of letters. Most spambots can’t do this, but your human visitors should have no trouble.

Google reCAPTCHA is available on Form Blocks, Newsletter Blocks, promotional pop-ups, and product waitlists. To add Google reCAPTCHA to your forms, visit Adding Google reCAPTCHA.


Reduce spam using a confirmation email

Another great way to prevent form spam is to select Squarespace Email Campaigns or Mailchimp as your storage option. Both services send a confirmation email, which requires subscribers to confirm their subscription before they’re added to a mailing list.

If you use Squarespace Email Campaigns, the confirmation email is enabled for Cover Page newsletter signup, Newsletter Blocks, and promotional pop-ups. To learn more, visit Subscriber verification.

If you use Mailchimp, the confirmation email (which Mailchimp calls double opt-in) is enabled by default. To learn more, visit Mailchimp's documentation.
