Best practice method of distributing surveys by email

I would ideally like to distribute my internal survey using our internal email survey. That way, the users will recognise it as an authentic internal activity, plus the contact list will always be up-to-date.
_However_, I want to track respondents' answers, and when I click on "generate a trackable link for each contact", it directs me to create a custom contact list, which undoes all the benefits of sending from the internal email server.
Can anyone shed light on the best way to send internal surveys please ? Much appreciated.
