Before you start.
Talk to us ↗What does a result tell me?
Each check returns a valid, risky, invalid, or unknown result, with syntax, mail routing, and risk signals. Catch-all domains can be risky. An unknown result means the check was inconclusive; it is not an invalid address.
How do bulk checks work?
Upload a CSV in the console, run verification, and download the results. Each address has its own result and signals so you can decide which addresses to keep, review, or suppress.
How are checks charged?
A conclusive valid, risky, or invalid result uses one credit, whether you check through the API, the console, or a bulk upload. Unknown results are not charged.
Do credits expire?
No. Purchased credits stay available until you use them. There is no subscription or automatic renewal; add credits when you need more.
