To prevent email campaigns from being marked as spam, verify your custom domain name through proper email authentication. Here's how to do it:

Understanding Domain Verification

A custom email address matches your domain name (example: [email protected] for www.sampledomain.com). For Squarespace-registered domains, verification is automatic. Third-party domains require either:

1. Transfer to Squarespace (automatic verification)
2. Manual DNS record verification

Manual Verification Process

1. Access Your DNS Settings:

• For nameserver-connected domains: Use DNS settings panel
• For DNS-connected domains: Modify records through your provider

2. Locate Verification Records:

• Go to Email Campaigns settings
• Under Sender Profiles, click Authenticate
• Note the two required records

3. Add DNS 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 settings]
