Comment 2 for bug 810229

Most projects work around this by setting their branches' default reviewers to another team that has a contact address (to prevent the emails from going directly to the members) and the actual team of reviewers as a member (so they still have full review privileges).

For example, branches maintained by the Launchpad team are owned by https://launchpad.net/~canonical-launchpad-branches, but their default reviewer is set to https://launchpad.net/~launchpad-reviewers. ~launchpad-reviewers' mailing list gets the review notifications, and ~canonical-launchpad-branches is a member so its members can review without being spammed.
