Do you validate email addresses?
With paid plans, we have a free service to validate your contact email addresses before they're added to your account. You need to submit at least 25 addresses per batch for this service. To validate email addresses, we run them through a multi-factor test. This process identifies misspelled email addresses and filters out old, abandoned email addresses so you can avoid adding them to your email account.
Eliminating inactive email addresses may lower your bulk email service costs, but more importantly, it will help reduce bounced email addresses and spam complaints. Rest assured, the contact email addresses you submit for validation are never stored, shared, sold, or used in any way. This valuable service is not offered with the Free Plan.
