Change content language in Email using Sendgrid plugin

[sebastian5]

Hi
I am using the sendgrid plugin to send automatically emals to my users.
The thing is that now I need to set the language of the content of the email dependig the language that that user has set in the db, I am using the app text to full fill the content of the email. My question is, is there any option to change the language of the email according to the language that the user has in the db ? I am really stuck here.
thank you !
