How can I change the language of the subscription details?

How can I change the language of the Show subscription details email block.

For what it’s worth, I use the Flair theme.

This is controlled by the ghost core. The theme cannot change it.

And I guess I can’t mess with the core as it’s not self-hosted right?

Correct. I do believe it’s possible to turn it off under newsletter settings - that might or might not meet your needs.

I will leave it is a detail that I like, but I wish it was possible to have it in Spanish. Thank you Cathy for being so thoughtful. Fuz night.
