Cold email breaks in the same places every time — a broken SPF record, too many DNS lookups, a DMARC policy that enforces nothing, a domain quietly on a blocklist. No signup, no limits, no data stored. Most checks resolve straight from your browser.
I build and repair cold email infrastructure for a living, and I kept writing the same throwaway scripts — expand an SPF record and count the lookups, find a DKIM selector without being told what it is, read the DMARC XML that piles up in a mailbox nobody opens.
So I turned them into 24 tools and put them online for free. No signup, no rate limits, nothing stored. Most run in your browser over DNS-over-HTTPS, so what you type never reaches my server.
The one I use most is the SPF lookup counter — the 10-lookup limit silently breaks authentication and almost nothing tells you you've crossed it.
Happy to run a check on any domain in the comments and explain what's wrong. Curious which tools people find missing.
