I Need Emails in The Real Estate Investing Niche

I run a marketing agency and need more emails that I can use in my cold emailing campaign. I am looking for emails of those who are real estate investors. I need someone who knows where to go to find these emails as I do not know where to find them. I will be verifying all email addresses so I need high quality emails. If you do well, I will have recurring work for you and many referrals in the future :)
