Frequently Asked Questions

Everything you need to know about our verification accuracy and credit system.

How does real-time SMTP verification work without sending an email?
Our engine connects directly to the target mail server (MX host) and initiates a standard SMTP handshake up to the recipient validation stage (RCPT TO). Once the server confirms the address exists (250 OK code), our socket disconnects cleanly without ever sending an actual message to the recipient.
Do my credits expire at the end of the month?
No! All verification and email finder credits purchased on ValidatorMails never expire. You can use them today, next month, or next year at your own pace.
What is a Catch-All email and should I send to it?
A Catch-All (or Accept-All) server accepts incoming mail for any address under its domain even if the specific mailbox doesn't exist. We pinpoint catch-all domains separately and score them so you can decide whether to send or verify their decision-maker pattern.
Is my customer data kept private and secure?
Yes, absolutely. We adhere strictly to GDPR, CCPA, and enterprise privacy standards. We never sell, share, or monetize your contact lists. All files are encrypted and auto-cleaned on disk.
