Hi,
I searched for how to do this, and only saw somebody write that it could be done... But how?
As you know, thanks to "human investigation" by Amazon SES, I cannot use their service, so I'm stuck with my web host :(
My host has a limit of 500 mails per hour - which I didn't know - and which could explain the low opening rate when I sent out to a list of 1300 subscribers. Almost 2/3 never got the mail.
So if I can set up the system to send to 500 at a time, it will "only" take me three hours to reach the 1300 subscribers.
Stupid people at Amazon make me really angry :( But there's nothing much to do, I guess.
