An emotion-filled mail when your best efforts are not being appreciated:
"Last but not least, a little bit of faith in the team is necessary to go forward.
We don't mind if a better team replaces us, because we are really proud how a small team has given their best effort to make the project a success so far.
A bad product would never have attracted billion dollar companies to feature their product in the app, and this gives us all the more reason to give even more effort, but we do need everyone to put their trust on the team.

I think this long email with explanation has eaten up a lot of time, so will need to get off for now.

Apologies in advance, if this sounded a little harsh, probably it's the passion talking :)"
