Email verification

5 vendors · updated 2026-09-15 · 1 without enough data for a score

Hosted email address validation and deliverability checking tools, ranked by the public disclosures we can verify.

Public transparency score, not a product or security rating. Transparency means: published on the vendor's own site, readable without a login, found by us at the addresses we checked.

Email verification is an emerging category: we have scored 4 vendors here, fewer than the 5 we need for a ranking. A median of two figures is one of the two, and a market comparison drawn from it would be a statement about one company. So there is no rank, no median and no band distribution on this page - only what we found at each vendor, with the source.

Every result links its source on the vendor page. A grey segment means we could not measure it, not that it is missing. See how we score.
