Automated emails – configure template & send details

Automated Emails. Is there a way to configure the style & settings for these. We have WPMU HTML emails templates installed for our WP emails, but the M2 emails are just;

a. being delivered in plain text format?

b. showing as “Sent from –” instead of what we have in WP dashboard settings?

If you need dashboard access, please let me know how I can submit these to you.
