What is Delivmail?
Delivmail helps your emails reach the inbox instead of the spam folder. It is an email tester and a DMARC monitoring tool in one place.
Why it matters
Gmail, Outlook and the others decide in a split second whether your email is trusted. If your domain is badly set up, your server is on a blacklist or your message looks like spam, your email lands in spam, or is refused, and nobody tells you.
Delivmail shows you what these providers see, and tells you what to change.
The tools
DMARC monitoring
Gmail, Outlook, Yahoo and others send daily reports about the mail sent with your domain. Delivmail reads them for you and shows who sends mail in your name, and what fails.
Blacklist lookup
Check an IP address or a domain against 20+ public blacklists, and get help to be removed from them.
Domain scanner
Check the DNS of a domain in one go: MX, SPF, DKIM, DMARC, and the usual mistakes.
What a test checks
-
SPF, DKIM and DMARC
Is your email really coming from you? These three records prove it to the receiving servers.
-
Blacklists
Is your sending server or your domain on a spam list?
-
Content
Does your message look like spam? (SpamAssassin, the filter used by many servers)
-
Sending server
Reverse DNS, encryption (TLS), shared platform or your own server.
How to use it
01
Test
Send an email to your test address and read your score.
02
Fix
Follow the advice in the report: DNS records to add, lists to leave, content to change.
03
Watch
Add your domain to DMARC monitoring to be warned when something breaks, then move safely to a stricter policy.
