Steps
- 1
Check your domain with the email check tool and confirm MX, SPF and DMARC records exist.
- 2
Enable DKIM signing for the domain (see the DKIM and DMARC guide).
- 3
Send a test message to a checker such as mail-tester.com and work on raising the score.
- 4
Avoid shouty subjects, shortened links and large attachments, and only email people who asked to hear from you.
- 5
If Microsoft flags a legitimate message as spam, report it as a false positive through their official tools.
Notes
- For bulk marketing use a dedicated sending service rather than hosting mail.
