Constant Contact hosts your email list and automatically performs critical list management
functions. These functions can include: signup for new subscribers, editing capabilities so that
subscribers can edit their own profiles, and the ability to unsubscribe with one click. Because
you are required by law to process an unsubscribe request within 10 days, the unsubscribe
functionality alone is critical to successful email marketing.

In addition, Constant Contact handles the bounced emails for you. If you use your email
system, you are probably overwhelmed by the bounces that you receive in your email box.
Constant Contact will manage bounces, differentiating between reasons for the bounce
(including full mailbox, vacation message, nonexistent address or blocked).
Managing these critical list management functions using your standard email system is time
consuming, confusing, and prone to error.
