Appointment confirmation via WhatsApp

How it works
- 1
Import your contacts
Customers from your phone or a .vcf file – once, in a minute.
- 2
Say or type one sentence
“Add Thursday 8 am at Walker's and ask him on WhatsApp if that works.”
- 3
The assistant prepares everything
The appointment is saved, the contact recognised and the message written – you see it first.
- 4
Send with one tap
“Send in WhatsApp” opens your chat with the text ready. You press send – or copy the text.
Why this way – and not automatic?
From your own chat
Your customer gets the message from your number, as always. No unknown sender, no bot.
No extra costs
No WhatsApp Business contract and no per-message fees – the feature is included in both plans.
Nothing goes out unchecked
XMS Calendar never sends anything itself. You see every message before it goes.
SMS or e-mail too
If a customer doesn't use WhatsApp, the assistant prepares the same message as an SMS or e-mail.
Frequently asked questions
Does XMS Calendar send messages automatically?
No. The assistant only prepares the message. You send it yourself with one tap in WhatsApp, your SMS app or your e-mail program.
Do I need WhatsApp Business?
No. It works with your normal WhatsApp – and just as well with the WhatsApp Business app if you use it.
What if the contact has no number saved?
Then WhatsApp opens with the text ready and you pick the chat yourself. You can also add the number to the contact or copy the text.
Does the message mention XMS Calendar?
Yes, it ends with a short line “Message prepared by XMS Calendar AI” and a link. You can still edit the text in WhatsApp before sending.
