How to Authenticate Your Email Domain for Mailchimp, Constant Contact, and Other Services

If you're using PhotoBiz Version 9 or higher and your domain’s DNS is managed through AWS Route 53, you can update your DNS zone records directly from your PhotoBiz account. This makes it easy to verify your domain and improve email deliverability when using third-party email services like Mailchimp, Constant Contact, Flodesk, or others.

Why Email Authentication Matters
Email authentication helps protect your domain from being spoofed and ensures that your emails are more likely to reach your subscribers' inboxes. Most email marketing platforms will ask you to add DNS records to authenticate your domain using methods like:

• SPF (Sender Policy Framework)
  
  
• DKIM (DomainKeys Identified Mail)
  
  
• DMARC (Domain-based Message Authentication, Reporting & Conformance)

You’ll usually receive specific TXT or CNAME records from your email provider that need to be added to your domain settings.

Important: DNS management is only available if your domain is using AWS (Route 53) name servers.
If your domain is still using our legacy name servers at Rackspace, this feature will not be available.
