Email authentication helps prevent your campaigns from being marked as spam. For custom email addresses matching your domain (e.g., [email protected]), domain verification is essential for email deliverability.

If your domain is registered through Squarespace, it's automatically verified. For third-party domains, you can either:

• Transfer the domain to Squarespace for automatic verification
• Manually add verification records to your domain's DNS settings

Adding Verification Records Manually

1. Access Your DNS Settings:

• For nameserver-connected domains: Edit through DNS Settings panel
• For DNS-connected domains: Edit through your domain provider

2. Locate Verification Records:

• Open Email Campaign settings
• Under Sender Details, click Authenticate
• Note the two required DNS records

3. Add Required Records:

First Record:

• Type: CNAME
• Host: squarespace._domainkey
• Data: squarespace-domainkey.squarespace-mail.com

Second Record:

• Type: TXT
• Host: _dmarc
• Data: [unique code provided in authentication window]
