Email subscriber verification can help reduce spam marking and improve email deliverability. Here's what you need to know:

Verification Options

Two main verification methods are available:

1. Google reCAPTCHA

• Invisible security feature that prevents bot submissions
• Enabled by default for form blocks and newsletter blocks
• Works with form blocks, newsletter blocks, and promotional pop-ups
• No action required from visitors

2. Confirmation Emails

• Sends verification email to new subscribers
• Available for form blocks, newsletter blocks, promotional pop-ups
• Also used for Acuity Scheduling opt-ins and free member sites
• Can be disabled when reCAPTCHA is enabled

Setting Up Verification

For newsletter blocks and promotional pop-ups using Squarespace storage, at least one verification method must be enabled:

• Access Email Marketing settings panel
• Click Verification Options
• Enable/disable reCAPTCHA or confirmation emails
• Customize confirmation email message if desired

Customizing Confirmation Emails

To modify the confirmation email:

1. Go to Email Marketing settings > Verification Options
2. Click Customize Email
3. Edit message text and style
4. Modify subject line and preview text
5. Send test email to verify appearance
6. Save changes

Troubleshooting

If subscribers don't receive confirmation emails:

• Check spam folders
• Add [email protected] to contacts
• Verify email address accuracy
• Try subscribing with different email address

For 404 errors during confirmation:

• Reconnect mailing list to form storage
• Ensure domain points correctly to Squarespace site

Note: Verification options are not available for checkout subscriptions, manually added addresses, or imported contacts. EU users should ensure compliance with local regulations.
