What is the difference between an Active and Unverified status?
In Express Email Marketing, "Active" status indicates subscribers whose email addresses have been confirmed as valid. Valid email addresses must be formatted correctly (for example, name@emailaddress.com) and have successfully received campaign emails. When you send a campaign that includes active subscribers, it is immediately sent.
An "Unverified" status indicates subscribers whose email addresses have not yet been confirmed as valid. To validate unverified subscribers, they must have successfully received three email campaigns, click a link from the first email campaign, or load images from the Express Email Marketing campaign. When you send a campaign that includes unverified subscribers, they receive your email within 48 hours after the initial delivery.
