FAQ

Frequently asked questions

How accurate is verification?
Real-time SMTP and MX checks deliver high accuracy and flag catch-all or risky addresses so you only send to safe inboxes.
Do credits expire?
No. Email Finder credits are one-time packs that never expire — use them whenever you need.
Can I verify a list I already have?
Yes — upload any list for bulk verification, and invalids are removed automatically before you export.
Is there an API?
Yes. Verify emails programmatically inside your own tools with the MailOptimal API.
