Got a list of 500k email addresses that needs cleaning.
Will provide you with a "list.csv" and a small neutral, business related "email.html" (NOT XXX)
I will need a "list.csv" of all emails that returned "send status OK" or Status 2.x.x (RFC1893).
Also the HTML email will have a personalised image URL with recipients ID so that I would know who opened the email. Therefore it is not just a matter of pinging the addresses
Please note that this is NOT a harvesterd list.
Looking forward to your bids!
