Email Security Audit Online

The Email Security tool on 101IP performs a full audit of a domain's email security: checks SPF, DKIM, DMARC and BIMI, analyses the configuration and assigns a grade from A+ to F.

What the tool checks

SPF — authorised sending servers and policy strictness (-all / ~all / +all);
DKIM — presence of public keys for email signing (17 selectors checked);
DMARC — policy for emails that fail SPF/DKIM (none / quarantine / reject);
BIMI — brand logo in email clients (bonus point).

Grading system

A+ — SPF with -all, DMARC p=reject, DKIM configured, BIMI present;
A / B — all key settings present, but policies are not at maximum strictness;
C / D — some settings are missing or misconfigured;
F — critical standards (SPF, DMARC) are not configured.
