I wouldn't worry about that too much, if they ignore your email then it ends there. I don't think anyone will put your email on a worldwide blacklist because you sent a feeler email out.

I would be worried about sending my personal information that appears on my resume (phone numbers, address, full name) unwarranted to someone. I would start by sending a quick email explaining your skills and maybe a link to a portfolio or github, and ask about openings. If they express interest then I would further pursue. If they don't, all they know you by is your email address.
