Marketing Cloud Next - Meet Gmail and Yahoo Bulk Sender Requirements (SPF, DKIM, DMARC, Unsubscribe)

Domain Authentication

To protect end users, emails must be properly signed and authenticated. Emails must meet these authentication standards: Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain Message Authentication Reporting & Conformance (DMARC).

To meet this expectation, set up authenticated domain for sending email in Marketing Cloud Next (this is a requirement before emails can be sent). More information on email authentication can be found here. To verify that your domain is properly authenticated, you can use a third-party site, such as aboutmy.email, mail-tester.com, or mailgenius.com.

One-Click Unsubscribe

All promotional emails must offer a one-click unsubscribe workflow. Additionally, you must process all unsubscribe requests within 2 days.

All Marketing Cloud Next emails with a promotional classification contain a list-unsubscribe header, which provides a one-click unsubscribe option for the recipient server and helps fulfill this requirement.

Limited Spam Complaint Rates

As a bulk sender, keep your effective spam rate at or below 0.3%. To help meet this requirement, consider these steps.

• Send relevant content to only engaged segments.
• Only send promotional emails to recipients who have explicitly opted-in and given consent.
• Remove inactive Google accounts from your subscriber list. Messaging an inactive account increases your bounce rate.
