A Mailfloss alternative that resolves catch-all
Mailfloss quietly cleans your email platform on a subscription, which is convenient, but on catch-all domains it flags rather than resolving. Giggal.ai returns a real result, pay-as-you-go, at $9.90 per 10,000 against its $40 prepaid.

How Giggal.ai verifies catch-all addresses
Mailfloss is built to run in the background and clean your list automatically, and for that it does a standard verification that flags catch-all without confirming the mailbox. 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 |
