E-mail Hell: E-mail to Anon Addresses Land in Spam

Please be EASY for I am a NEWBIE...
I am looking for advise on the following situation:
I am extracting leads for people who post and solicit a need for what I have to offer. No CPA's, Links and all those other trixs
I purchased Clist E-mail Extractor Software (It works wonderful)
I also use it over a VPN
Now, when I go to use the leads generated from Clits e-mail extractor, all e-mails land in the SPAM Folder when sent out in bulk...
I have an e-mail scheduler which allows me to schedule e-mails. I can send 1 per minute. This worked 50% of the way earlier today when syndicated with smtp.gmail. I fear using smtp.mydomain. I don't mind rotating I.p and proxy and smtp every 10 emails.
However, what are the best practices, here? What are my options?
I've researched Yahoo Mail Genius, Ninja Blaster and something else.
I don't want to go wasting money I don't have trying this and that
Can someone steer me in the right direction

Don't make the email to aggressive !
Your writing should sound a bit friendly and not a promotion speech!
