The easiest way is to go to the SEND button and choose the option "MESSAGES".
This will show a popup where you can choose the group you wish to send to.
"Groups" can be e.g. "delivered", "viewed", "accepted" and "declined".
You can choose to send either to one or to multiple groups and send a message to many.
Messages and reminders are for free - after making your first invitation, save the date or card sending to a recipient.
First the invitation, save the date or card has to be sent to a recipient before you can send a message/reminder.
