With accurate, speedy postal address validation, you won't waste another dime sending undeliverable mail. Our address validation is CASS-certified by USPS, and our seamless, streamlined process gives you time to focus on what really matters for your business.

How it works

  1. Whenever you scout an address, we automatically verify that address for you.
  2. When you create a single or bulk mailing, we'll let you know if any addresses are undeliverable.
  3. We'll only send mail to deliverable addresses in a mail campaign, unless you otherwise say so.

How we verify addresses

Is it deliverable? Our address validation is CASS-certified by USPS for over 169 million domestic addresses to ensure your product gets to its final destination. Our robust data cleansing means less returned mail, lost mail, and operational waste.

Is it formatted properly? Our platform ensures your addresses adhere to proper postal formatting and autocorrects them when they don't. Got some piece of information wrong? We'll automatically fix it. It's that simple.
