Thanks, SD, I understand that, but how to solve the problem? Cutting and pasting the URL from the received e-mail, into a converter such as you linked, and then using it kinda defeats the objective.
I either need to stop the conversion (ie send the link as if it were "encapsulated" plain text and not actually seen as a link) or automatically interpret the conversion either on mail receipt or when the link is clicked in the received e-mail.
None of the options I have found in any of the sending mail clients allow me to do anything that has the slightest influence on stopping the encoding.
