Add branding to the email communication. People are not expecting an email from "Do" and therefore ignore it. If DO information can be added at the bottom of the page, people will be able to find you while my meeting notes will look professional.

I 100% agree. If we would get user acceptance within the company the communication eMails etc. needs to be branded with the companies Logo at least. Samuel is right that receiving a meeting invite from DO, users would get confused as they have no direct relation to Do. Branding for us would be a must have or a showstopper using it.
