Do you have a message to inform people about e.g. sudden program changes or as a welcome message? Just send broadcast message to all attendees at once.
Probably the best way to get to peoples attention is by sending push notifications. And, if people choose to disable push messages they will receive an email instead.
When somebody replies to a broadcast message you will be the only one who receives it. So other participants will not be bothered by messages that are meant for you.
Rather send a on-to-one message instead of group messaging? No problem, just select that person from the attendees list and send individual messages instead.
As administrator you are able to send broadcast messages right from the app. Now you can reach anyone at anytime from anywhere.
No contact details needed
You do not need to have contact details of people as we will send your message to their account within the app.
