Email Deliverability Checker
Is your domain set up so your email reaches the inbox and can't be spoofed? We check SPF, DKIM, DMARC and MX live and grade it.
SPF, DKIM and DMARC — what they do
These three DNS records prove your email is really from you, so inbox providers trust it instead of junking or blocking it:
- SPF lists which servers may send mail for your domain. End it with
-all(strict) or~all(soft) and keep it under 10 DNS lookups. - DKIM adds a cryptographic signature to each message so receivers can verify it wasn't altered. Your provider publishes a public key under a selector.
- DMARC ties SPF and DKIM together and tells receivers what to do with mail that fails —
p=none(monitor),p=quarantine(spam), orp=reject(block). It also sends you reports viarua=.
Checking live DNS from a server is something a browser-only tool can't do. If your mail is landing in spam, a weak SPF/DMARC setup — or a blacklisted IP — is the usual cause.
