I'll be more than happy to have the option to notify colleagues/reviewers/developers via email about new comments in XD prototypes (Even if they don't have an Adobe account). This way, I'll not have to send an additional email when I reply to their (colleagues/reviewers/developers) comments. Thanks!!!

Please add option to notify people via e-mail about new comments in Xd prototype when they do not have Adobe account. Every time when I add comments I need to send e-mail to my customer: "Please check new updates in prototype". Please fix that.

It would be nice to notify someone outside of my AdobeID email of notifications from XD.

For example...
If a client makes revisions on a mockup in XD, I'd like the project manager (who doesn't have an Adobe ID) as well as the designer to get notifications. Right now the project manager has no way of knowing if the client left feedback. This is an important part of any revision process when working in a team of project managers and designers.

It would also be nice to save out these revisions into a list format for recording history within a project but lets take one step at a time.

It would be very useful if the client gets an email notification whenever he's being tagged in a comment. They don't receive any notification even if they have an adobe account. When I make a new comment and I tag the clients I then also to poke them via email in order to get a reply from them.

I couldn't find this feature request yet...
