How could I find out how many users have each email setting?
I’m asking as only about a tenth of users watching a topic are being emailed post notifications.
Thank you.

それらは、Preferences/Emails ページにあるものですか? そのフィールドは user_options テーブル(email_level)にあり、プライベートメッセージ用のもの(email_messages_level)もあります。
こちらが機能すると思います。特定のトピックをウォッチしているユーザーを抽出し、メールレベルごとにカウントします。
**キー** | メールレベル | :-: | :- | 0 |常に 1 |不在時のみ 2 |なし-- [params]
-- int :topic_id
SELECT tu.topic_id AS topic_id,
uo.email_level,
COUNT(*)
FROM user_options uo
JOIN topic_users tu ON tu.user_id = uo.user_id
WHERE tu.notification_level = 3
AND tu.topic_id = :topic_id
GROUP BY topic_id, uo.email_level
もし私が何か間違っていたら教えてください。![]()
![]()

こちらも機能すると思います:(そして、もう少しきれいに表示されます)
