keep getting unhandled response message. Have found on here that gmail sucks.. What is the best one to use? I have tried slowing way down 20 mssgs 1 port . i am totaly new to this any help is appreciated.
Gmail is a free service not really suitable for bulk emailing because of its strong delivery limitations. You can use it but it will be a real pain. I recommend to read the following page: What mail server can I or should I use with MaxBulk Mailer?
During years I have made everything to make MaxBulk Mailer work with Gmail but they always add something new to make the bulk email delivery more and more difficult.
