What are best practices for sender email addresses in email marketing?

Summary

Best practices for sender email addresses in email marketing involve a combination of branding, technical configuration, and ongoing monitoring. The chosen address should reflect your brand identity, be recognizable to recipients, and align with the email's purpose. Authenticating your sending domain using SPF, DKIM, and DMARC is crucial to prevent spoofing and improve deliverability. Actively monitor your sender reputation, blocklist status, and inbox placement rates. Avoid 'no-reply' addresses to foster engagement and monitor feedback loops to quickly address issues reported by recipients. When introducing new IP addresses, warm them up gradually. Test your email configuration and preview your emails across different clients and devices.

Email marketer from Email Geeks explains it is more of a branding question than a deliverability one. Suggests using name@ to differentiate mail streams, or addresses that clearly state the purpose (newsletter@, pr@). Recommends avoiding role addresses and being creative to improve user experience, giving examples such as offers@, sale@, or even got5onit@ for a cannabis store.

What the documentation says

4 technical articles

Best practices for sender email addresses from a technical perspective center on implementing email authentication protocols and feedback mechanisms. Setting up DKIM helps prevent email spoofing and ensures trust from recipient mail servers. SPF records prevent spammers from forging 'From' addresses, improving deliverability. DMARC builds upon SPF and DKIM to provide a policy for handling authentication failures. Finally, feedback loops (FBLs) enable senders to receive reports when recipients mark emails as spam, aiding in identifying and addressing sending practice issues.

Key findings

  • DKIM: DKIM helps prevent email spoofing and ensures recipient mail servers trust messages from your domain.
  • SPF: SPF records prevent spammers from forging your domain in the 'From' address.
  • DMARC: DMARC provides a policy for how recipient mail servers should handle messages that fail authentication checks, building upon SPF and DKIM.
  • FBLs: Feedback loops (FBLs) allow you to receive reports when recipients mark your emails as spam, helping you identify and address issues.

Key considerations

  • Technical Expertise: Proper implementation of DKIM, SPF, and DMARC requires technical expertise.
  • Ongoing Monitoring: Regularly monitor feedback loops (FBLs) and sender reputation to identify and address deliverability issues promptly.
  • Policy Enforcement: Define a clear DMARC policy to instruct recipient mail servers on how to handle authentication failures.
  • Authentication Alignment: Ensure that your DKIM and SPF records are properly aligned with your sending domain.
