Get started with DataValidation by linking an ESP account or uploading an email list (via .csv). For every list (imported through ESP or uploaded to our system) you will receive an Always Free Email Assurance Report.
This report card provides you the percentage of subscribers falling in each Email Assurance Grade category. This will help you make an informed purchase decision - we believe it should always be free to know the status of your email list, at any time. Your Free Email Assurance Report will provide you with the following information.
A+ Deliverable + Engagement Activity: The emails given a grade of A+ have been determined to be deliverable. They also have engagement history concerning email clicks and opens. These addresses are always Safe!
A Deliverable: The emails given a grade of A have been determined to be deliverable. These addresses are also Safe.
B Accepts-all: These emails have been deemed as "Accepts-All". A server that accepts all email means that the hostname has been set to accept any mail. This could also mean the email address in question may be a spam trap. This is commonly seen in business email addresses and in many cases, the server will accept all mail and then bounce it back to sender, which in turn hurts the sender's IP Reputation. We do not recommend sending to the "Accepts-All" category. All emails with a grade of B should be segmented (until later confirmed valid).
D Indeterminate: In checking for an email, we were not able to do anything. The email address seems to have a mail server that is running and accepting connections, but we are unable to connect. We do not recommend sending to the "Indeterminate" category. All emails with a grade of D should be segmented off your list.
F Undeliverable: The emails given a grade of F have been deemed as undeliverable and are therefore, invalid. These emails are unsafe to send to! These addresses should always be unsubscribed from your email database.
After reviewing your Always Free Email Assurance Report you'll be able to make an informed purchase decision. Upon purchase, you will have access to your list's Address-by-Address Analysis.
