Protect your sender reputation

Remove disposable addresses and minimize risk

Bad actors are working tirelessly to find new ways to manipulate your systems and create new (illegal) opportunities for themselves. And now that disposable email addresses are widely available, it makes organic list building that much harder for legitimate senders.

Our email validation API is able to identify most types of disposable addresses, so you have one less thing to worry about when building your email lists the right way.

Why we are different

Create a competitive edge

What makes our email verification API unique is that each address is checked against a database of cached data that comes from the over 400b emails we deliver every year as a leading email service provider. And to add yet another layer of accuracy we also check against data that comes directly from the mailbox providers themselves for an unmatched level of performance.
