We have a total of just over 2,000,000 email addresses. They're all being approached for a legitimate NON-MARKETING NON-SALES campaign, so it's perfectly ok under CAN-SPAM (just in case anyone cares). We have used datavalidation.com service to determine which addresses we can send emails to using a major ESP we're working through. Approx. 68,000 email addresses are considered A+ and A and can be emailed according to the results. However, datavalidation.com wants a huge sum to provide us with the A+, A, and also the B emails that we simply can't afford. Therefore, the bottom line is that we need to know which address those are. We've purchased AtomicMail and left it on all weekend and it's just processed through a few thousand emails. That's a nonstarter as we have to get this list out no later than Thursday night. So anyone who can do this validation (and possibly even send out the emails from one of our domains) please contact me right away and let's see if we can make a deal. And please, you don't have to tell me that sending emails to such a list is going to have a very low response rate, is not as good as messing around on social media, getting SEO, blah blah blah. I know, I know, I know. We need to get these out in a couple of days and there is no faster way of getting the results we need.
