Hello @JohnL751 ,
When you send a link in an email through us, the system adds coding to that link so it can be tracked for click reports. This is something that, by Compliance, needs to be attached to any links sent through us. The reason the links appear "normal" in the test sends is because only live sends will have the links re-coded for tracking. If you're worried about emails not being delivered due to the coding on these links, it may be worth speaking with Deliverability and providing any examples of contacts you know for certain had the email filtered away from them. You may want to go through the steps to become self-authenticated, if you suspect the potential for spam filtering is significant enough. For more info on self-authentication, you'll want to bring it up with the Deliverability team.
