Allow Discovery emails to be sent from personal email address instead of Aha!

What is the challenge?

Researches are concerned that customers will not reply to email that don't come from them directly, or that spam filters will block the emails (format: 4b9501674f193de02d538718-accountname@iad-prod2.mailer.aha.io>)

What is the impact?

Sending emails outside of Discovery instead, missing out on the time savings of using automated Discovery macros.
