How it works
six checks on every signup

Every submitted address passes through each check before it reaches your database. Each one runs in milliseconds.

Format check

Catch typos and malformed addresses before they enter your list.

Delivery check

Verify the domain has working MX records and can receive mail.

Email profiling

Identify role-based, catch-all, and high-risk address patterns.

Mailbox verification

Confirm the mailbox actually exists with a live SMTP handshake.

Developer API

Grab an API key and drop validation into any form or workflow with a single endpoint.

Mailing lists

Upload a CSV and clean your entire list in one go.

FAQ

How much does it cost to start cleaning my email list?

You can start for free — no credit card required. Scrub operates on a pay-as-you-go model by default, so you only pay for the emails you validate, with no minimum spend. If you'd rather have predictable billing at higher volume, flat-rate monthly plans are also available.
