How QuickEmailVerification and Instantly handle catch-all
QuickEmailVerification returns catch-all as a status without confirming the mailbox. Instantly returns catch-all addresses as Valid, Invalid or Risky, and does not contact the Risky ones by default. 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.
