Email campaign subscriber authentication uses two main methods to protect against spam and ensure legitimate signups: Google reCAPTCHA and confirmation emails.

Google reCAPTCHA

• Works invisibly to prevent bot submissions
• Enabled by default for form blocks and newsletter blocks
• Can be used with:
  • Forms with required email fields
  • Newsletter blocks using Squarespace storage
  • Promotional pop-ups

Confirmation Emails

• Sends verification email before adding subscribers to list
• Used for:
  • Form blocks with email sign-up
  • Newsletter blocks
  • Promotional pop-ups
  • Free Acuity Scheduling opt-ins
  • Free member site sign-ups
  • Cover page newsletters (v7.0)

Customizing Confirmation Emails:

1. Access Email Campaign Settings > Authentication Options
2. Click "Customize Email"
3. Edit text and layout
4. Style to match branding
5. Modify subject and preview text
6. Test email using the "Test" button

Troubleshooting Failed Confirmations:

• Check spam folders
• Add [email protected] to contacts
• Verify email address was entered correctly
