Stop bounces before they burn your domain
Three checks per email: syntax, domain, mailbox. You see exactly what passed and what didn't.
No credit card required
How we validate
Every email goes through three layers. You see what each one found.
Syntax Check
RFC-compliant format validation. Catches typos, missing @ symbols, and malformed addresses instantly.
MX Records
Queries the domain's mail server configuration. No MX record means that email isn't going anywhere.
SMTP Verification
Connects to the mail server and asks: does this mailbox exist? The most accurate check possible.
