Populate textfield to an Extenal site

Hi to everyone, is it possible or any way to pre-populate textfield on an external site you dont own??

ex. “http://cpa.eatlessfeelfull.com/?sid=2022

there is an email textfield and i want that when i went to that page the email will be automatically have a value on it. so i will not type the email.

is it possible to get it via the the url
ex “http://cpa.eatlessfeelfull.com/?sid=2022&email=sample@yahoo.com

Whoever owns eatlessfeelfull.com would have to look for the query string parameter and handle it, nothing you could do without an agreed upon protocol.
