Email Applied: How to Implement an Email Preference Center

Simple Preference Centers
This model limits everything to a few easy choices:

➜ Change or update email address. One-third of all email addresses change each year. Give interested subscribers the opportunity to provide you with a "better" (i.e., more accurate) email address. Without this functionality, a subscriber who wants to update their email address has to opt out and then resubscribe. That's a lot to expect, and the odds are you'll lose the chance to communicate with them going forward.
