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 – WordPress@oursite.com” 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.

Thanks,

Paul
