I am working on a startup and one of the features we thought we would implement is the ability to send email to other users/groups who use the application. Email isn't a core piece of what we do, we just thought it would be nice to have that ability.
At first I didn't question it, but now I am starting to think it's not a good idea. Personally I prefer to use my own email whenever emailing someone. People already have so many different apps and things they need to sign into or navigate to. Why would they send an email from my app? It seems like a feature we just don't need.
I'm asking this question here because to me this is a UX question. Which user experience is preferable - emailing from your day to day email client, or doing it in some random application that you have to log into?
One thought I did have is that email is often hard to track conversations...so if we had something where the email conversation could be tracked in our app (through replies etc) then we could provide some sort of useful conversation repository. It wouldn't be cluttered up by emails not related to this application.
