Email Validation & Deliverability API
Keep bad addresses out of your signup forms.
Check addresses and domains before they create bounces or messy contact lists. The service spots typos, disposable inboxes, unreachable domains, and shared role addresses, then returns a clear result for each address. Use it in signups, lead forms, imports, and cleanup jobs.

Common questions

A 'risky' email is technically capable of receiving mail, but is of lower quality. This usually means it's a role-based address (info@), a free provider, or contains a typo.
