Is your domain ready to send?
Enter a domain to read its MX, SPF, DKIM and DMARC records. Every issue comes with an explanation and a link to the fix.
We look up public DNS records only. DKIM is checked on common selectors.
SPF
A TXT record listing the servers allowed to send for your domain. Keep it to one record and under 10 DNS lookups.
DKIM
A signature your mail provider adds to each message, published as a TXT record under a selector. Receivers use it to check the message wasn't changed.
DMARC
Tells receivers what to do when SPF or DKIM fail, and where to send reports. Start with p=none, then tighten. Read the 20-minute setup guide.
Do this for a whole list, not one at a time.
