I think emails from gerrit lacks important context. For example, when someone add you as a reviewer and ask for review, gerrit only send a message with just the author message.

This makes it really hard to understand that you asked to review the CL, especially if you already receive many gerrit email (due to WATCHLIST).

For example, today I was asked to review a CL, but the email message only contained PTAL without any additional indice that it was addressed to me and not my WATCHLIST.

Note that this is the only email I received in that thread from gerrit, no message telling me I'm one of the reviewer. Can the gerrit email be changed to include the list of reviewer?

Something like adding the following: "Reviewers: Sylvain Defresne, ...".
