Worth knowing
Bouncer
- Credits can also be bought as a monthly subscription that refills each month; the page shows its price only inside the calculator.
- Bouncer Shield, for form checks, is a separate monthly subscription priced by the number of checks.
- The Deliverability Kit is sold separately from verification credits.
- Bouncer does not warm up inboxes or manage DMARC records; the kit only tests them.
ZeroBounce
- Warm-up and DMARC monitoring come only with ZeroBounce ONE, and it covers a single DMARC domain.
- Unused tests, monitors, searches and warm-up seeds on ONE do not roll over; only verification credits do.
- The FAQ says credits never expire with an active ONE subscription; otherwise expiry rules may apply depending on when they were bought.
- The free credits need a business or premium email domain at sign-up.

- Checks addresses as they are typed into sign-up forms and can block invalid, malicious or fraudulent entries by address or IP.
