You can send two types of emails to your event goers: an event reminder & a post event follow up.
To send an email to your event's attendees. Start by heading to the email tab in your main navigation. Select the event whose customer list you want to send the email to. Next fill in the basic information about your email blast and you are all set!
Tip: You will be able to preview and send tests of your email after you save a draft of your email.
*Bonus Tip: A great use of the event follow up is to link to a feedback form so that your customers can share their experience with you.
