Understanding verification statuses
Tomba returns detailed statuses beyond the basic valid/invalid that most tools give you.
Valid
Email exists, server confirmed the mailbox is active and accepting mail.
Catch-All
Domain accepts all emails. Tomba uses AI to determine if this specific address is real.
Unknown
Server didn't respond clearly. May be temporary. Worth retrying later.
Risky
Email might work but has risk flags low engagement domain, role-based, or greylisted.
Invalid
Mailbox doesn't exist. The server explicitly rejected this address.
Disposable
Temporary email from a disposable provider. Not a real business contact.
