The only way to get proof of mailing is sending your return by certified mail.

 

You may be looking at Colorado's Contact Us By Mail page.  The delay time when sending a document by certified mail is minimal, generally no more than one day.

USPS priority mail with tracking would be sufficient proof that the return was delivered and will also report the mailing (post mark) date.
