Improve the performance of your email campaigns with validation services from Deep Sync. Our full-service email validation enables you to determine the validity of the email addresses in your database with ease. We use a multi-step process to analyze each email independently to determine its potential for deliverability. This includes identifying valid email addresses, invalid and/or deactivated email addresses that will hard bounce, known SPAM traps, improperly formatted addresses, and more.

Following our evaluation, we add result and action codes that provide easy-to-interpret insights about each email address. You can use this information to make informed decisions about deploying to the respective email addresses.
