I'm looking to scrape email addresses of local businesses and then email them. I'm offering a legit service to them so this would be traceable right back to me. I'm based in the USA and I know there is the Can Spam Act but I'm not sure how that relates to business-to-business email. Anyone have any experience with this? Do I need to be concerned about sending out 500-1000 emails in bulk? Should I space the emails being sent out (example 30 per hour) so it appears more natural?
