How Kickbox and QuickEmailVerification handle catch-all
Kickbox flags accept-all addresses with a field rather than resolving them. QuickEmailVerification returns catch-all as a status without confirming the mailbox. 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.
