ZeroBounce alternative
Looking for a ZeroBounce alternative? OrbiSearch resolves catch-all emails that ZeroBounce simply flags as "accept_all", returns results in seconds rather than 48 hours, and costs up to 91% less. No subscription, credits never expire.
ZeroBounce returns "accept_all" for catch-all domains without verifying individual mailboxes. Verify+ takes up to 48 hours and has a 33.1% false positive rate because enterprise systems quarantine test messages rather than bouncing. OrbiSearch resolves catch-alls in seconds without sending any emails. See how ZeroBounce stacks up against BounceBan on catch-all resolution for the side-by-side breakdown.
At 1M emails ZeroBounce charges $3,199. OrbiSearch charges $311 for the same volume, 90% less. At 100k it's $649 vs $103.
ZeroBounce bundles warmup, inbox testing, blacklist monitoring, scoring, and finder. If you only need verification, you're subsidising features you'll never touch.
30-50% of B2B email lists contain catch-all domains. ZeroBounce and OrbiSearch handle them very differently.
