Hi alexandreholland,
First things first, did you created your triggered email?
if not, you can follow the instructions on how to do so here:
https://support.wix.com/en/article/creating-a-triggered-email
also, I have tried to recreate your code and it works for me, however the email automatically reached my ‘Promotions’ folder instead of my ‘Primary’ folder in my inbox.
Check your ‘Promotions’ and your ‘Spam’ folders in your inbox and see if the email is there.
Good Luck!
