Personnalize email // Add token

Hi Marketo Community,

I have a question and I hope somebody can help me.

I want to personnalize an email with the token [First Name]. I want to send this email with an external list.

When I want to add a token in the email and I choose "Insert token" in design stuidos, I can't see the differents tokens from my list.

Can you help me please to add my token and personalize my email ? 

Best regards.
