Email verification
Reduce bounces and protect sender reputation
Verify email addresses before you send to cut bounce rates, protect sender reputation, and block fake sign-ups. We run live checks for deliverability, mail server connectivity, inbox availability, and more without sending an email.
Check whether an address is safe to send to before it hurts deliverability, wastes credits, or damages sender reputation.
