Spring Harvest Mailing Campaign

Must have skills and experience with complex email campaigns. Fresh IP's, Domain rotation, SMTP etc... All emails will be going to one location, through a relay system. This requires considerable skills to avoid bot detection. Every 500 mails will need to alter subject and text slightly. Should rotate email origin every 4 to 5 mails. Have large volume of contacts prepared in CSV to export to the right candidate whom can get through the email relay system. Look at something like C R A I G S L I S T S to get an idea of similar platform we need to address campaign towards. experience a must. Not posting, or flagging. Looking for experience with mailing to similar platform. Have sample contact list for the right candidate to demonstrate ability. Will award a continuous contract for successful mailing of 100 to 200k mailings every 3 weeks. text only content so complex to monitor or gauge inbox etc..., have test set in place. We have several other projects for the right candidate as well. initial volume of 500k emails. We also have need for email to sms, simple text. Please only contact if you can do the work.
