Frequently Asked Questions
What does Mail Tester measure?
You send a test email and the tool gives a score out of 10 based on SPF/DKIM/DMARC correctness, blacklist presence, content quality and message structure.
Why is my email score low?
Common causes: missing or incorrect SPF/DKIM/DMARC, the IP being blacklisted, or spam-like content. The report explains each item separately.
Where do I start to improve email deliverability?
First set up SPF and DKIM correctly, then add DMARC, and make sure the sending server's IP is not blacklisted.
