I understand that Gerrit has a lot of email features already (Email Template, email ingest, etc.
https://gerrit-review.googlesource.com/Documentation/config-mail.html) but it seems to be a few features away from being able to send email the way 'git send-email' does it (to encourage integration/coming-together with mailing-list-based review):
1) having a concept of patch series in mail templates (Gerrit already have the 'series' concept in the form of Relation Chain) such that template can have a variable for the commit index and commits count in the series (to produce patch [3/10] in a particular email, for example.)
2) patchset ID of the first commit in a Relation Chain can be used as the series version (like v5 in the example below)
3) being able to send 'cover letter' in 'git send-email' sense (summerizing all the commit subjects and file delta.) I think this can be done as a 'Send' option in the Reply interface? (perhaps something like "Send as series'?)
Example of send-email format:

What do you think?
