Worth knowing
DeBounce

- The pricing page also offers a monthly option at 8% below pay-as-you-go; its prices show only in the calculator.
- DeBounce verifies addresses only; it has no warm-up, inbox placement tests or DMARC tools.
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.
