Wholesale Prospecting with Email and/or Facebook Ads

Hi everyone!

I'm not a wholesaler, but I'd like to talk to anyone who is that uses email as part of their prospecting process.  I'm building out use case models for a marketing software that I run that connects to Facebook and email lists.  We've had a lot of success with Real Estate agents and their email marketing list, and I'm curious if it could be helpful to wholesalers.

Is it possible to get email addresses alongside other contact information when you acquire a list?

Have you had success in using email marketing or Facebook ads as part of your process?

This is not a pitch in any way.  I'm just gathering information.  Thanks in advance!
