Built a warmup calculator that reads your SPF/DKIM/DMARC instead of asking you to guess them.
Every warmup calculator I've used is a form pretending to be a tool. Domain age, SPF, DKIM, DMARC, they just ask you, and most people answer from memory or don't know their own DMARC policy is inherited from the root domain instead of missing.
So I built one that actually looks it up instead of asking:
- Domain registration date via RDAP (not asked)
- SPF walked through the full include chain, checked against the 10-DNS-lookup limit in RFC 7208, a record can look fine and still be broken past that limit, and +all gets scored near zero instead of "configured"
- DKIM checked for revocation, not just presence, an empty p= tag revokes the key per - RFC 6376, so a checker that only asks "is p= there" calls a dead key healthy
- DMARC read with the sp= subdomain fallback from RFC 7489, since most tools report "no DMARC" on a sending subdomain that's fully covered by the root policy
the way it just reads your actual DNS records instead of making you copy paste is such a relief. whoever thought of skipping the guesswork deserves a coffee
@yakuplkrm Thanks Yakup! That was the whole point, honestly every other calculator I'd used just asks you to self-report SPF/DKIM/DMARC status, and most people genuinely don't know if theirs is right. Reading the actual records (and walking the SPF include chain, checking for DKIM revocation, etc.) felt like the only way to make the timeline actually mean something instead of just being a generic "wait 4 weeks" rule. Appreciate you noticing that part specifically 🥲
Finally a warmup tool that actually pulls my DNS records instead of making me paste them in. Saved me a solid ten minutes on setup.
@vedat02op Thanks Vedant! Glad it's saving you real time. Would love to hear how the warmup timeline works out for you!
