Clicking the link in e-mail, eM client warns me the hyperlink is different from the link that is shown in the e-mail BODY. It is handy, and can be even more handy if the eM client can show in this warning popup the new button to open link that is shown in the BODY instead of current, usually tracking one.
Maybe even automatically using the link in BODY instead of hyperlink which is usually tracking link, sometimes to a third party domain.
