Policy decisions by administrators at domains that receive mail can often have an adverse impact on your ability to send mail. These policies may result in changes to the message being sent that can cause things to work in a manner in which they are not intended.
One example of this phenomenon is seen in mail sent to United States Army domains. We have recently been made aware that links in mail sent to addresses which end in us.army.mil have been broken. One of our deliverability consultants reached out to the postmaster there and received the following reply:
Links within the us.army.mil domain are blocked. What you can do is copy the link and paste it into the address bar of a browser and remove the "blocked". The blockage is in place for security purposes.
As you can see, this is a policy decision on the part of the Army. In order to protect their users from malware downloaded from malicious URLs, they have made a policy decision to add “blocked” to all links sent to their system. This is a policy that they feel works well for them and which they are not willing to review.
Being aware of your recipients and the policy environments in which they use email will help you to send mail to them in a way that is useful and meaningful to them. ExactTarget's Deliverability Services team is devoted to staying on top of issues like these.
