Email Deliverability Checker
Check a domain’s SPF, DKIM, and DMARC records so your email reaches the inbox instead of spam.
This free tool is launching soon
What this tool checks
- SPF record and syntax
- DKIM signing record
- DMARC policy
- MX records for mail delivery
Why it matters
SPF, DKIM, and DMARC tell receiving mail servers that your email is genuine. Without them, legitimate messages land in spam and attackers can spoof your domain. These three records are the baseline for being trusted.
FAQ
Common questions
Do I need all three of SPF, DKIM, and DMARC?
Yes. SPF lists who may send for your domain, DKIM signs the message, and DMARC tells receivers what to do when a check fails. They work as a set.
What DMARC policy should I start with?
Begin with a policy of none to collect reports without affecting delivery, then move to quarantine and reject once the reports look clean.
