How Mailfloss and Apollo handle catch-all
Mailfloss runs a standard check that flags catch-all without confirming the mailbox. Apollo markets a seven-step process that distinguishes valid from invalid on catch-all at 91%. 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.

Mailfloss is $40 at 10,000, $300 at 100,000 and $1,200 at a million. Apollo is priced per user seat, with verification bundled rather than sold by volume. Both numbers come straight from each vendor's own pricing, so put them next to the volume you send each month.
