To prevent unwanted spam email, some Internet Service Providers (ISP's) block messages from senders whose email addresses are not in the recipient's Address Book or Safe Senders List.

At ExactTarget we want you to receive the emails that we send to you. To ensure your messages reach you in the future please add ExactTarget to your Address Book or Safe Senders List. It should take only a few minutes.

We have provided instructions for the most commonly used ISP's. Please select your ISP from below.
