03 · MESSAGES
Talk to everyone, or just one.
Send one update to everyone, or a private note to one family. Replies come straight back to you.
Broadcast
One message, everyone on the list. Time moved, bring swimsuits, parking is round the back. Goes to all guests or just the ones who said yes.
Personal message
A line only one guest sees. A note for grandma, a heads-up that the cake has no nuts, a reminder for the friend who never replies.
