More than one email per day

Hi guys -
I do webinars that require me to send out a reminder on the day of the event as well one an hour prior then a thank you email with a copy of the recording. When will we be able to use APWT to use emails in this way? I understand not wanting anyone to send a barrage of emails throughout the day, however certain industries require that more than one email goes out to a tag list in one day. Please help.
