I have a spreadsheet of approximatley 750,000 email addresses, which i need cleaned, meaning i need to remove any dead domain names and also i need to know if the email address is still active, if the email address is no longer present then i need it removed, also if the mailbox is full i also need the name removed.
I expect that in my list there will be a lot of dead addresses however i am happy to lose volume as long as what remains are actual workling email addresses.
Please only bid if you can guarantee that the good list will not be returned as unknown user or email address does not exist, Payment will be made after i have recieved a demo of 1000 email addresses which i will test, upon successful completion (ie 80% work) then full payment will be made.
I would like for this to be an on going process and have lots opf data waiting to be cleaned.
I would like to award this project today and get it started.
Please tell me how you will achieve this so i know your confident on what you are doing.
