Emails for rtl languages have ltr direction

[hnaseri (Hosein Naseri)]

Can the site-font be added to the digest email as well?

I think not as far as I know. Never heard of custom fonts in emails. So even if it would be possible, It seems its not a good idea.

the invitation email, password changing email, … , are ltr

If someone point me to all email templates, I’m willing to take a look at all of them.
