TOPIC: Email Registrants - can I limit how many get sent per hour

We're on a shared hosting environment, and are not allowed to send more than 300 emails per hour, or else our email gets turned off. We have an event with over 500 registrations right now, and need to send out a mass message to them.

Is there a way to have email registrants send out a mass email in batches (e.g. 200 now, 200 in an hour, etc.) until everyone has received it?

Not at this time.
