A Kickbox alternative that resolves catch-all
Kickbox is a developer favourite with a clean API, but on accept-all domains it sets a flag and leaves the mailbox unconfirmed. Giggal.ai returns a real result, at $9.90 per 10,000.

How Giggal.ai verifies catch-all addresses
Kickbox returns a deliverability result alongside an accept_all field. On an accept-all domain it sets that flag and hands the address back without confirming the mailbox, which is honest but leaves the decision to you. We route those addresses down a separate path and return one of four results, so the real mailboxes come back deliverable rather than flagged.
| Result | Meaning |
|---|---|
| Deliverable | The mailbox exists and will accept mail |
| Undeliverable | The mailbox does not exist |
| Risky | The address exists but carries deliverability risk |
| Unknown | We could not verify the address, and the credit is refunded |
