The ability to specify a from name in email steps has been released. You can configure emails to now send from "My Company via no-reply@flowdashmail.com"

On the one side, its hot. Simple integration with imap/smtp and sending email from own domain.

On the other side, if you need email system, you should use sendgrid/mailchimp and other tools, because someday you will need reports, permissions and a lot of stuff, that big email companies provides you.

In my opinion, fast email integration will be great for prototyping.
