At first the plugin appears to be free, but then when I needed to rewrite the email (just to rewrite it, the "default" e-mail the customers receive is this :
Your bookings for following items are confirmed:
Bien-Être - Albi:

You can judge by yourself it just ugly, certainly on purpose, to make want to pay about $10 a month.
The infomation to pay for this module is hidden until you actually want to change the text.
It would have been acceptable to make us pay if we need to send over the 100/month limit, which would have meant the business is already working great, but actually it is asked at the very beginning.
So the one star rating is for all the time lost on this plugin and the dishonnest strategy.
We would have paid gladly for sending more than 100 e-mails a month, we would have paid too to be able to customize the email adresses and advanced theme e-mails, but just to rewrite the text when we just start working with this app, certainly not.
So if you look for a free app, this isn't really one, unless you accept to send to your customers a very bad looking e-mail, barely understandle by someone not into the plugin configuration.
