Sender Best Practices

Yahoo Sender Hub Free Intermediate

Yahoo's own rules for bulk senders, the counterpart to Google's sender guidelines and written by the people who enforce them.

  • Bulk senders need SPF and DKIM, and a DMARC policy of at least p=none that passes, aligned with SPF or DKIM.
  • Marketing and subscribed mail needs a working one-click List-Unsubscribe header, and unsubscribes must be honoured within two days.
  • Keep the spam complaint rate below 0.3 percent, measured against mail delivered to the inbox.
