Protocol Reference 

## What these tools check

Six email authentication protocols, each published as a DNS record. Together they determine whether your email is trusted, displayed with your brand logo, and encrypted in transit.

SPF

TXT @ domain

Declares which servers are authorized to send email for your domain. Receivers check the sending IP against your SPF list.

DMARC

TXT @ \_dmarc.domain

Tells receivers what to do when SPF or DKIM fails - monitor, quarantine, or reject. Enables aggregate and forensic reporting.

DKIM

TXT @ selector.\_domainkey.domain

Cryptographic signature attached to each email. The receiving server verifies the signature against a public key in DNS.

BIMI

TXT @ default.\_bimi.domain

Displays your brand logo next to authenticated emails in supporting clients like Gmail, Apple Mail, and Yahoo Mail.

MTA-STS

TXT @ \_mta-sts.domain + policy file

Forces TLS encryption on inbound mail delivery, preventing downgrade attacks and man-in-the-middle interception.

TLS-RPT

TXT @ \_smtp.\_tls.domain

Instructs receivers to send reports about TLS connection failures when delivering email to your domain.

Trust & Transparency 

## 11 tools, zero signups,  
no data collection

We built these tools because checking your email authentication records should not require handing over your email address. Every lookup queries live DNS directly and returns results to your browser - nothing is stored, logged, or tracked.

## When you need  
more than a snapshot

Free tools check one domain at a time and give you a point-in-time result. DMARC Report monitors all your domains continuously - processing aggregate and forensic reports, classifying senders, tracking trends, and alerting you when something changes.

Moving from `p=none` to `p=reject` typically takes 9 to 18 months, with 90+ days per policy phase. You need continuous monitoring - not periodic spot checks - to get there safely.
