ZeroBounce vs NeverBounce

ZeroBounce is a long-established verifier wrapped in a broad deliverability suite. NeverBounce is a verifier known for deep CRM integrations and cleaning lists inside your stack.

How ZeroBounce and NeverBounce handle catch-all
ZeroBounce scores catch-all addresses from 1 to 10 with AI rather than confirming the mailbox. NeverBounce marks accept-all addresses and resolves only a small share of them. Catch-all domains accept mail for every name, so a normal check cannot tell a real mailbox from a dead one, and this is usually where a list quietly loses good contacts.
How Giggal.ai handles catch-all. Giggal.ai resolves catch-all addresses to a real deliverable or undeliverable result at 1.5 credits in a run, or 2 standalone.
