Gather CL Leads and email my content

I have specific areas of CL that I sell to, the people want my service but it's too slow to contact them one by one. Bulk marketing to them doesn't work due to frequency, IP, email address use etc. So, I need someone to gather the emails in the CL areas I tell you to, and provide a service that manually emails my content to those emails with the proper setup so they actually get to the inbox and don't get denied by CL or go straight to spam. I have tested 5 freelancers so far who all say this is no problem, but the results speak for themselves and the clicks are substantially lower than when we do our own manual emailing from multiple addresses here in the USA with my own employees. This means obviously they aren't ending up in the inbox for a variety of reasons because the titles, content, etc is the same. I am doing yet another test here, and if you achieve the click rate or close that we do manually, which probably requires a manual process, multiple IP addresses and email addresses, then there is a ton of work. This isn't any sort of spam whatsoever, we just need an outsourced scalable solution to reach the volume of CL listers that want our service without getting shut out. Please only respond if you are a CL master for this test run.
