In my WIP, I have a few text and email exchanges, and I'm not sure how to show them.

For texts, I just italicized:

Eva and I are going out tonight. Enjoy your peace.
Madison’s text completes this perfect day. A big smile is etched on my face on the trolley ride home.

Is this ok?

For emails, I can't find a formatting that I think looks fine. Do I need to detail To, From, Subject, etc... for every email? Do I leave more space before and after, to make it stand out? And less space between lines?

Should I maybe forget the whole email idea and have them communicate another way?
