How credits work
One check. One credit.
Every email verification and every domain check uses one project credit, regardless of the result or provider type.
Your balance stays yours.
Starter and purchased credits do not reset or expire. Buy manually, or opt into a $10 top-up when a project reaches 1,000 credits.
The public demo is separate.
No-key checks are limited to 10 per hour and never spend a project credit.
