We've made it easy to send an event reminder to your guests. Sign into your account and go to Invitations > Manage Events. Find the event that you want to send a reminder for and in the drop-down list of options, select "Send Reminder". Select the group of people you would like to send the reminder sent to, select an eCard template if you created one and then click the "Create eCard" button. If you selected an eCard template, you can edit it before sending it. You can edit the list of recipients before sending as well.
CorpNote also records the details of the reminder eCard so you know the day you created it, when it was sent and to whom.
