Email Domain Authentication Guide for Campaigns

Custom email domain authentication prevents your campaigns from being marked as spam. A custom email address matches your domain (e.g., [email protected] for www.sampledomain.com).

For third-party domains, you can either:

• Transfer the domain for automatic authentication
• Manually add authentication records to DNS settings

Required DNS Records:

1. CNAME Record

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

2. TXT Record

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

1. Login to my.ionos.com/domains
2. Select domain > Domain Details
3. Click DNS > Add Record
4. Add CNAME and TXT records
5. Save changes

Important Notes:
