I trying to send an email to all my customers, its not something I've done before so it a bit of a learning process.

The problem I had was, as I sent the email the script timed out with only about a quarter of the customers emailed.

Is their a way to select the rest (or a sections of) of the remaining customers to email.

I can't resend it to all customers as those those that already have will get it twice.

Their are a mixture of html and text only emails.

Any help gratefully recived.
