If you're using notmuch and Gmail, I'd recommend taking a look at gmailieer - https://github.com/gauteh/gmailieer https://github.com/gauteh/gmailieer. It uses the Gmail API to fetch mail into a local maildir and keeps the tags synced bidirectionally. The downside is that for whatever reason the Gmail API doesn't support the mute label, so having that tag sync is not possible. (If a Googler reads this, please fix that! For others, there's already an issue filed as referenced in the gmailieer readme.)
