ExactTarget IP Addresses for Inclusion on Whitelists

What Is Whitelisting

Whitelisting is the process of configuring a spam filter to exempt certain email messages from being filtered or rejected. In this case, it refers to configuring your own corporate mail server so that it doesn't reject or filter the email campaigns you send via ExactTarget. For more information on email whitelisting, see http://en.wikipedia.org/wiki/Whitelist.

There is also the need to whitelist calls made from within our application outbound to clients.  Our cloud-based application exists within data centers located in Indianapolis and Las Vegas.  If there is a special function required to pull data that is located outside of these platforms, our servers make these requests.  We have hundreds of servers that perform such requests through a specific set of monitored proxy addresses for security reasons.  These are located in the table form below.

Note: You do not have to do this. Some spam filters are smarter than others, and whitelisting is not always necessary. Feel free to skip this process until and/or unless you find that you have an issue receiving copies of your own email messages. Remember, this only applies to how spam filters work when sending emails messages from yourself to yourself. This is specific to clients sending to themselves, and is an issue completely unrelated to successfully delivering mail to the regular recipients on your email list.

Most importantly, don't spam. Permission is the key to the inbox. Companies who send mail only to recipients who
have explicitly requested to receive that mail are the most successful at getting their email messages delivered.

ExactTarget has the tools and expertise to measure your current deliverability and help you investigate and fix any problems you might run into. Services include our Inbox Preview, Inbox Detective, Reputation Monitor, and Campaign Insight. These features must be enabled in your account, so contact ExactTarget for more information.

Why Whitelist ExactTarget IP Addresses

Your servers can interact with the ExactTarget applications for several different reasons:

• You use the ExactTarget API to create and send your email and SMS messages
• You use the ExactTarget for Microsoft Dynamics CRM integration
• You use the ExactTarget for Appexchange integration for Salesforce

To properly use the API or the integrations, you must whitelist the ExactTarget server IP addresses to allow uninterrupted communication. Because server configurations are unique to each instance, you must take this information and apply it to your system.

Previously, email messages with your from address or domain were probably only sent from a mail server located
on your internal network. Spam filters usually only expect that email from your domain will come from this existing,
internal mail server. Email messages that claim to be from you, but actually come from any server outside your
network, are more likely to be blocked as a spam, spoof, or phishing email. Some filters also reject email messages
that have the same domain name in both the "from" and "to" addresses in the headers, if the messages did not
originate inside your existing internal network.

Spammers love to dress up their email messages to look like they originated from somewhere they didn't. Many
companies protect themselves by allowing email from their own domain through only if it comes from the company's
mail servers. If that weren't the case, it would be easy for a spammer to create an email message appearing to
be from the head of your company telling everyone to take the day off with pay. They could send it from any email server and fool recipients.

ExactTarget IP Addresses

ExactTarget accounts utilize a pool of IP Addresses that vary depending upon send volume by default.  It is possible to configure an ExactTarget account to use a Dedicated IP, often in conjunction with Private Domains.  If your account utilizes a Dedicated IP, that address will need to be whitelisted.  Otherwise, the following addresses should be whitelisted based upon the instance of your ExactTarget account.

NOTE: To determine what instance you're on, see Accessing the ExactTarget Application.

NOTE: To determine if your account utilizes a Dedicated IP, please contact Global Support. To discuss enabling your ExactTarget account with a Dedicated IP, contact your Relationship Manager.

Include the domains bounce.exacttarget.com and exacttarget.com with your whitelisting process.
