Hi there Desical,
Thanks for getting in touch with us! Interesting question here, let me say we still don’t have that functionality baked into the plugin but maybe I can help crafting a snippet to accomplish this.
To send an email after the event is created should be fairly easy, just hook to the ‘publish_tribe_events’ (new-status_post-type) action make the needed checks and send email.
Scheduled notifications can be trickier, Can you elaborate a bit more what you expect from this functionality? A simple way can be to set up a cron job via wp_schedule_event to run everyday and check if events will be taking place in the given time (next day for example) and send notifications if needed.
Please let me know your thoughts about this,
Best,
Nico
