Subscriber

What is Subscriber?

When an individual voluntarily subscribes or opts-in to an email list, they become a subscriber. The Email Assurance Grade of a list is estimated using the individual deliverability codes of the email addresses obtained from the address-by-address analysis. Senders can get useful information about their subscribers from the deliverability codes.
