Hello @TerryH090 ,
If you're seeing your name in the header of your email, you can edit that aspect while building your email. If you're seeing that only when you receive the email, but not in the editor, it means there's something in your email program that's automatically reinterpreting that email address as being your contact info. Regarding the unsubscribe link, that's determined based on the receiving address of a contact, when sent live. Test emails will default to the account owner's info for the non-functioning test unsubscribe link.
For your LinkedIn link, please check what URL you're adding. If the URL you're trying to insert is something only the owner of the account would see, then that won't work for others trying to access it. If the LI page is private or otherwise requires some degree of special access to see, then that may also cause issues when trying to link to it. If you have confusion about your page's URL, I'd recommend reaching out to LI's support for further assistance on getting the link you need.
