Did you use segmentations to build dynamic content or are these 3 separate emails?
If these are 3 separate emails, go ahead and just send yourself the sample email.
If you used segmentations, there are 2 ways:
1. Preview the email in the language you want and use the Send Sample from the Preview.
2. Create a static list of records that are segmented correctly to FR, IT, and EN. Then, send a sample using that static list, making sure to check the box at the bottom to send all variations.
NOTE: the view as webpage link does not work when you have segmentation and send tests. it will always show default content. you need to send the email as a single flow action for that link to propagate correctly.
You can also preview using the above method.
Or choose leads in that segment when sending samples as well.
But yes, there is no "English" vs "Italian" tokens. It's based on segmentations
