Hi. Thanks for your interest in using the ticketing part of our plugin suite.
Unfortunately, we don’t have this functionality natively yet.
I believe you’re requesting the same thing as one of our existing feature requests: https://tribe.uservoice.com/forums/195723-feature-ideas/suggestions/8391186-reminder-emails-for-x-days-before-event
Please do add your vote there.
This allows us to gauge interest in this particular feature request, which helps us prioritize our development efforts.
Last but not least, we have a pretty great Refund Policy so you can buy one or many of our add-ons and thoroughly test them.
I hope this info helps. Let me know if you have any follow-up questions.
