Email Sender Authentication Requirements

Updated over a week ago

As part of our ongoing commitment to keeping you informed about impending changes from Google and Yahoo!, we'd like to highlight a critical update. Starting in February, both Google and Yahoo will enforce email sender verification through authentication protocols such as SPF and DKIM.

SPF (Sender Policy Framework) authenticates the sender, permitting only authorized servers to send emails from your domain. Conversely, DKIM (DomainKeys Identified Mail) verifies that a message remains unaltered during transit. By incorporating these protocols, you bolster your email domain's security against spoofing attacks and fraudulent activities, while simultaneously enhancing email deliverability.

Key Changes:

  1. SPF Record:

    • Record Type: TXT

    • Content/Value: v=spf1 -all

  2. DKIM Record:

    • Record Type: CNAME

    • Host Name:

    • Content/Value: Note: If you're using GoDaddy, set up the DKIM record as follows:

      • Record Type: CNAME

      • Host Name: em._domainkey (your domain is assumed)

      • Content/Value:

Action Steps:

  1. Navigate to your domain's DNS settings.

  2. Add or update the SPF and DKIM records as specified above.
