Verify your DKIM in seconds—stop spoofing, protect your brand, and keep real mail in inboxes. Enter your domain + selector to validate your DKIM record and see exactly what to fix.
What you’ll get
- Instant DKIM validation — confirm a valid TXT record exists for your selector and that it parses correctly.
- Clear, readable results — we show the core tags (
v,k,p) and flag formatting pitfalls (like broken strings). - Actionable guidance — move from weak or missing keys to best-practice deployment with confidence.
How our checker works
- Enter your domain (e.g.,
yourcompany.com) and selector (e.g.,selector1). - We look up the DKIM TXT at
selector._domainkey.yourcompany.com. - You get a plain-English report with findings and next steps.
We analyze (at a glance):
- Record presence & syntax:
v=DKIM1; k=rsa; p=<public>. - Key strength: highlight 1024- vs 2048-bit guidance and rotation needs.
- Selector hygiene: one TXT record per selector; multi-string TXT must concatenate without spaces
Common issues we flag (and fix)
- Missing or malformed record — absent
v,k, orp, or split lines breaking the key. - Weak keys — 1024-bit keys still exist; we recommend moving to 2048-bit where supported.
- Wrong selector — multiple services use different selectors; we help you identify the right one(s).
Best-practice guidance
- Use 2048-bit RSA keys where possible and rotate periodically.
- Publish DKIM as a TXT record (CNAME only when your provider requires it).
- Pair with SPF + DMARC for alignment, reporting, and enforcement.
