So what is the big secret with mass mailing. i have searched forums, scripts, freelancers and everything i can think of but just cant get info about it.

 

i have a db of about 3000 registered members. i need to mail a newsletter on a regular basis.

 

the php script that i use works fine for small batches, but wont send more than 300 at a time.

it pulls the newsletter from a bd, and also pulls the emails from a db.

 

what is the "right way" to do this.

 

Batch mails?  multiple smtp's? 

 

i have had several freelance scripter work on this but cant solve my problem.

 

is there a single corect way to do this, is my approach way off the mark?

 

please help, or point me in the right direction.

essentially 2 ways,

 

1 is a good script that can queue the mailings, send off 20 - 100 at a time with a 10 minute pause between sends

 

the other way is to send them all out as a single message making all the emails a BCC

 

quite a few scripts that can queue up mail,

try testing a few out, if you still have trouble send me a message and I'll see if I can help

this is the script i am using at the moment. is this script badly written? can i modify this script to work corectly or should i start from scrach with a new approach?

all i need is to know that my newsletter is going out to all my members.

 

what is the most effective, batch or bcc?
