Hello Justin,
Great question, thanks for reaching out!
When someone purchases a ticket, then they will get the regular ecommerce emails of order placed, order completed, etc. (depending on the ecommerce solution you choose), and when set, then they will get an email containing the ticket itself.
Apart from these no other emails are sent out by the plugin.
If you would like to send out automated reminders to users, the you will need a plugin like Follow-Up Emails for WooCommerce for example.
I hope this helps in your decision.
If you have any more questions, I’d be more than happy to answer them for you.
Cheers,
Andras
