How to find out if the email is verified?

Every email we return has a status:
- Valid: the mailbox exists and accepts email.
- Accept-all: the company's mail server accepts every address, so we can't confirm this specific mailbox. Usually deliverable, but not guaranteed.
- Risky: the address may bounce.
- Unknown: the mail server didn't give a clear answer.
- Invalid: the address doesn't exist.

Credits are used only for Valid and Accept-all emails. Risky, unknown and invalid results don't use credits.
To check any single address yourself, use our free email verifier at aeroleads.com/email-verifier.
