Questions
Are these tools really free?
Yes, with no sign-up. The DNS checkers read public records, and the calculators and the spam word checker run in your browser. The Signal Detector has a daily limit per visitor, and the AI tools five uses a day.
Which should I start with before a cold email campaign?
Your domain: check its SPF record, its DKIM key and its DMARC policy, then plan a warm-up with the sending volume planner.
Do you keep what I type?
The calculators and the spam word checker never send it anywhere. The DNS checkers keep their answer for two minutes, so that checking again right after a change is quick.
