Premium Add-Ons

Take your notifications to the next level with one or more of these add-ons.

  • Reply by Email Add-on: Users can create new topics or replies directly from their mailbox. No need to click links or open the forums in a browser. Heck, they can even dictate their topics/replies if they want!
  • Bulk Mailer Add-on: Having trouble with mailout timouts because you have too many users? This is the solution. Integrate bbpnns with Mailgun or SendGrid and send messages in batches of 1000 instead of one-by-one.
  • Digest Add-on: Users can choose to receive daily, weekly, or monthly digests.
  • Opt-out Add-on: Users can choose not to receive any notifications, or simply unsubscribe from the thread with a single click. A must-have for CAN-SPAM and CASL laws!
  • bbPress Moderation Integration: Make bbpnns work with bbPress Moderation.
  • bbPress Private Groups Integration: Make bbpnns respect bbPress Private Groups rules.
  • BuddyPress Integration: Notify BuddyPress Group members of new Group Forum topics and replies. It also shows individual Opt Out and Digest settings in each user’s BuddyPress profile screen. Compatible with BuddyBoss!
  • MemberPress Integration: Make sure your members have access to Opt Out and Digest settings in their MemberPress profile screens, and only get notified of topics/replies they have access to.
  • Ultimate Member Integration: Make sure your members have access to Opt Out and Digest settings in their Ultimate Member profile screens.
  • AccessAlly Integration: A must for those using AccessAlly, so their users won’t receive notifications for forums they don’t have access to.
  • LearnDash Integration: Play nicely with LearnDash user restrictions to forums.

  1. Upload the entire plugin folder via FTP to /wp-content/plugins/.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.
  3. Go to the bbPress Notify (No-Spam) in the main admin menu -> Settings to customize the settings.


I’m using BuddyBoss instead of bbPress. Does this plugin work for me?

  • Yes! BuddyBoss forked bbPress and kept all of the inner workings. This means that anything that works with bbPress will also work with BuddyBoss.

Why am I not receiving notifications of a topic/reply that I created?

  • Make sure the setting to notify authors of their own posts is checked in both the Topics and Replies screen.

Where are the settings?

  • As of version 2.0, the settings are no longer in the Forums screen but have their own location in the Admin menu area.

People are getting timeouts when posting a new Topic or Reply. Why?

  • When a new Topic or Reply is created, bbpnns is triggered to send notifications regarding that new post. If there are too many recipients, it may take too long for bbpnns to iterate through the recipient list and the web server will throw a timeout message; the person posting it will think their message didn’t get saved. To get around this problem, turn on the option to send messages in the background. That will create a scheduled action for the next time the wp-cron runs, and bbpnns will try to override any time limits while running.

Why are some of my users not getting notified?

  • If you have not turned on Background Notifications, see the FAQ item above. If you have turned it on and some users are still not getting notified, it could be that your host is not letting bbpnns finish doing its thing, even though the timeout settings have been overridden. Some hosts will have scripts monitoring long running processes and have them killed, regardless of the PHP timeout values. A solution for this is to have bbpnns work faster, and for that we’ve released the Bulk Mailer add-on which connects with an existing Mailgun or SendGrid account and sends notifications to up to 1000 recipients in the time it would otherwise take to send to a single one.

Can a user turn off notifications?

  • Originally, this plugin was developed to alert Administrators of new topics and replies. After a few iterations, users requested the ability to send messages to other roles, which could then be characterized as spam. To allow your users to opt-out from receiving notifications, please consider purchasing the Opt-out Add-on or disable per-role notifications in favor of Overriding Core Subscriptions.

Does this plugin integrate with BuddyPress?

Does this plugin integrate with X, Y, Z Membership/Privacy plugin?

  • We can’t add support for all sorts of third party plugins inside the core bbpnns plugin. It would become way too bloated. However, we do support some of the more popular membership and privacy plugins such as Private Groups, MemberPress, AccessAlly and Ultimate Member. See the Premium Addons section above for the links to each one. If you’re using a different plugin and need support, reach out and let us know.
    We’ll look into adding it.

Can this plugin be customized?

  • If you have some WordPress coding experience, customizing should be really easy as we offer dozens of filters and actions. However, if you need help, reach out and let us know your specs for an estimate.

I had an issue with a premium add on to this plugin and the author was very responsive and helpful. Highly recommend.

I just installed this plugin. Thanks for solving this problem! Often my visitors are expecting to hear from me directly, so I need notifications to help me remember to check for any pending (hidden) topics. I am hopeful that this plugin will help me know when my visitors are trying to communicate with me using the forums. I also would like to get a notification on the WordPress admin back-end of the site whenever there is a pending (hidden) topic, or a new topic I have not yet viewed. Is this a feature that could be added?
