The default booking confirmation email won’t include the customer phone number. To add the customer's phone number to the email, you must create a custom email template.
How to create custom email template with customer’s phone number
1. Go to “Settings” and click “Edit” on “Notifications & Workflow”.
2. Under Store Owner Email Templates, click the “pencil” icon next to Store Owner Confirmation Email to create a custom email template.

3. Write the subject and email body using the tags. Add @customerPhoneNumber to add a customer phone number in your email.
Sample Template
Subject: @productName - appointment is scheduled Hi there, @customerName has secluded appointment for @productName. Customer name: @customerName Customer phone number: @customerPhoneNumber Service: @serviceName Date: @bookingDate Time: @bookingTime Thanks, @storeName
4. Click “Save” to save the email template.
Now, the customer phone number will be added to the notification email.
