I have a form that an administrator fills out to send a mass email to users. My host only allows 100 emails to be sent per minute. The script is set up to send 100 emails at a time, BUT the user has to manually click the "send next 100" link.

I want to set up a meta refresh to automatically send the next 100 after 60 seconds, however I can't figure out how to get the meta refresh to pass the query string.

Help?
