Players, GM not receiving any emails on forum activity

What do you and your players have set on your Account page where it asks you how often you want to receive email notifications? Once per day or Immediately?

I just ran a test on my end, and I was getting notifications instantly sent to my email box when players were posting replies on my game threads. Are you seeing this issue with all of your game's forum threads or for one in particular?

We created a Test forum thread on your game Reader Party. We doubled checked with one of your player's and they received the on-site notification of the post occurring. The next thing we attempted was to run a test on one of our games to make sure the immediate email notifications were going off, and shortly after are reply being added to a test thread, the GM of the game received an email regarding the post within five minutes of posting. What you and your players should double check is that you are checking the email accounts tied to Roll20 accounts to make sure you have the correct email addresses tied to them. Also, you may want to make sure your email client isn't auto filtering emails from Roll20 in a fashion where you can't see new posts.
