Constant Contact consistently delivers above 97% of the emails on its clients behalf into the
recipient’s inbox, compared to an industry average of 81%. This is measured by a third-party
company. Constant Contact maintains strong permission policies and has an active
anti-blocking team working with receiving ISPs on your behalf to ensure that your email is
delivered and delivered with proper protocols. We develop relationships with ISPs and are
white listed to be sure your permission-based email gets through.

Constant Contact monitors all outgoing email to ensure that all major ISPs and corporate
domains accept your email. If you are using your own email client, you may not know if your
email is being delivered. Often ISPs will just “drop” emails without sending a bounce message.
With Constant Contact, you will know which emails got delivered and why — or why not.
