Mangled tracking and unsubscribe links

[Souther]

It seems some links are getting mangled upon sending, is there something I should be doing to prevent this? the '=' in some of the requested URIs makes me think it may be due to line breaks in "quoted printable" encoded body content.

This isn't something I am doing explicitly and most link clicks and unsubscribe clicks work as expected, but the few that aren't are what is concerning, especially in the case of unsubscribes.

ome of the requested URIs makes me think it may be due to line breaks in "quoted printable" encoded body content.

That is exactly what it is, i am not sure 100% if we can do something to alleviate this, will do some research.

 

[frm.mwz]

Is it happening on
any delivery server for
any campaign (template/html code) for
any recipient
or can it be narrowed down?

I dont have enough data to narrow it down but from how I understand the problem it is happening because of factors which involve "quoted printable" encoded text. Switching to a different encoding type seems to be how other applications have tried to resolve similar problems.
