| Value for money | C$39 for a one-off 10,000, and credits never expire. Among its listed rivals DeBounce ($25) and Clearout ($32 a month billed yearly) cost less at that size. At scale it pulls well ahead: a million checks are $449, where Bouncer charges $2,000. | DAbout $129 for a one-off pack of 10,000 checks, or $79 a month billed yearly on ONE for 10,000 credits a month with warm-up and DMARC thrown in.

Enough to test, not to clean a list. | CA real free plan: 100 checks a month that refill, plus one inbox test, one server test and one blacklist monitor. You need a business email to get it, and 100 checks won't clean a list. |

Worth knowing
MillionVerifier
- There is no monthly credit plan; auto top-up buys a new pack when the balance runs low.
- EverClean has its own monthly fee based on list size, which the site does not publish, and works only through integrations.
- Verification only: no warm-up, inbox placement tests or DMARC tools.
- The smallest regular pack is 10,000 credits; a 2,000-credit pack for $4.90 is a one-time trial option.
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.
