Rating: 5.0 (1 reviews)

The industry’s longest standing secure and scalable contact validation solution. Build and maintain a clean and actionable database; reach and engage more people through reducing your bounce rate and protecting your sender reputation.

Verifying your email list is easy just drag & drop your email list into the window, or import it from your Email Service Provider (ESP). Briteverify scans the list to show you your total records and cost, at the click of a button you are off and running. After verification is completed, you can download your list, or automatically unsubscribe invalid and risky emails from your campaigns.

Really cool! Does it work with one-off emails or it has to be a bulk email file upload?

Yup, we have an API and a neat Javascript Forms script snippet (BriteForms), either of which you can use for one-by-one email verification.
