How to go through a business verification

Hello! I’m trying to get verified on websites like mailgun.com , sparkpost.com and etc and they’re asking me for a business verification:

“1. How do you source your email lists/contacts, and what are the URLs of these sources?”

“2.Could you please provide the URLs to your Terms of Service and Privacy Policy for our review?”

Does anyone know how i could answer them these questions. The problem is that i send emails to not obt-in, so i need like a “fake proof” or something.

Please, let me know what could be possible solutions.
