Start a new conversation without having to search for a client account first. This means you could contact unregistered clients and queue up a registration form or promo link.
Please note
If the phone number matches a known client account on your PMS, this will be auto matched
If there is already an open conversation with this number, this will be shown
WhatsApp messages will still require consent from the client
A client will still need to have an account on your PMS eventually so you can take payments and set up patients
