email to all users
 

This in theory seems to be a great feature, however in practice, it stops responding after 500 or so emails, and must be restarted. I've tried settings of 10, 5 and 3 at a time. Is there a hack that will build in a 30 second pause between pages? Example, if setting for 10 mails at a time, the screen displays a Next Page button and immediately refreshes to the next page. How about a 30 second pause before the page refreshes automatically?

Also, it would be nice to have a Pause / Resume button to manually pause the refresh next to the Next Page button. With a 30 delay before auto refreshing, an Admin could suspend the mail delivery until he hits Resume.

Are you sure it stops or is your server set so that you can only send 500 a day?, the bulk mailing should work just fine (i've sent out 20K before now and its worked fine), take a look at this mod by Paul M https://vborg.vbsupport.ru/showthread.php?t=201318 it will help you do what you want :)
