Giggal.ai

Giggal.ai checks whether an email address can receive mail, so you can clean a lead list before you send to it.

Ask Claude to verify one address or a list of up to 1,000 in a single request. Each result shows a status (deliverable, undeliverable, risky or unknown), a deliverability score from 0 to 100, whether the domain is catch-all, and whether the address is disposable, a role account or from a free email provider. Most addresses on catch-all domains get a deliverable or undeliverable result instead of risky. The same applies to mailboxes behind secure email gateways such as Proofpoint and Mimecast.

When Claude verifies a list, it gets a job ID. You can fetch the results of that job again for 48 hours without using credits, and check your remaining credit balance at any time.

You sign in with your Giggal.ai account over OAuth. Each address costs 1 credit, and new accounts start with 1,000 free credits. Giggal.ai only checks the addresses you give it. It does not find or guess email addresses, and it never sends email to the addresses it checks.
