Frequently asked questions about Tempo Checker
How is Tempo Checker different from a free blocklist?
Free lists are static snapshots. Tempo Checker's AI scraper and DNS/MX layer catch domains that spun up in the last few hours, not months.
Will it block legitimate customers?
No. Every verdict includes a confidence score and reason, so you can hard-block, soft-warn, or flag for review—never all-or-nothing.
How fast is the API?
Median response time is under 50ms, comfortable for real-time signup validation without perceptible lag.
Does Tempo Checker store the emails I send?
No. The service checks the domain in real time and does not retain full email addresses.
