Boosted Check

Understand your website and email-domain configuration.

DKIM checker

Look up the public DKIM key for a selector supplied by your email provider. This does not verify a signed message.

Inspect the DMARC record and core policy tags at the exact domain. Inherited policy and message alignment are not checked.

Look up A, AAAA, CNAME, MX, TXT and NS records with clear resolver status and observation time.

Review SPF, DKIM, DMARC and MX observations together. A DKIM selector is optional; missing selectors are marked not checked.

Inspect the published SPF record, supported syntax and visible policy. Recursive SPF evaluation is not included in this checker.

Check certificate names, issuer, validity dates and TLS trust for a public hostname.
