Sending letters to public email, how to organize?

Question

Marketing

Good afternoon,
I plan to send 10-20 letters a day to the email addresses indicated on the sites by their owners. So let's say cooperation proposals. Some recipients may mark the email as spam. What will happen to me in this case? How to avoid it?
Please do not throw poop, because in fact, letters of this kind are difficult to unambiguously attribute to spam. After all, people and companies are looking for each other. Services are not fake, and those to whom we write are really needed. How else to contact other than through the official contacts listed on the site?
If you have experience please share, thanks in advance!
