Email deliverability: It’s the cornerstone of email marketing strategy and planning. With Google and Yahoo both enforcing new email standards, your organization’s email authentication should be top of mind. In this article, we’ll highlight what’s changing, what to review across your organization and in your Salesforce instance, along with best practices to try.

What Are the New Requirements?

Beginning in February 2024, Google and Yahoo will require all email senders, both large and small, to comply with these requirements:

  • Authenticate your sending domain using SPF or DKIM authentication.
  • Maintain a low rate of spam reports.
  • Make unsubscribe easy for recipients (starting in June 2024, bulk senders must implement a one-click unsubscribe option).

For senders of more than 5,000 emails per day, two additional configurations are necessary:

  • The sender domain must be aligned with either the DKIM signature domain or the envelope sender (SPF alignment).
  • You must create a DMARC policy, even if it’s set to “none.”
