Frequently Asked Questions

What is email verification?
Email verification checks if an email address is valid and can receive messages. We connect to the mail server using SMTP protocol to verify deliverability without sending an actual email.
What do the results mean?

Valid: Email exists and can receive messages.

Invalid: Email doesn't exist or will bounce.

Unknown: Server restrictions prevented verification.

What is a catch-all domain?
A catch-all domain accepts emails to any address, even non-existent ones. For these domains, we can confirm the domain is valid but not the specific mailbox.
