Troubleshooting MailPoet Post Notifications That Won't Send

32 threads Sep 16, 2025

Content

Many MailPoet users rely on post notifications to automatically alert subscribers about new content. However, a common issue reported across various WordPress sites is that these notifications sometimes fail to send, disappear from scheduled tasks, or experience significant delays. This troubleshooting guide examines why this happens and provides practical solutions to get your post notifications working reliably again.

Common Symptoms of Post Notification Issues

Based on community reports, these are the most frequent symptoms users experience:

  • Notifications appear in scheduled tasks but vanish without being sent
  • Emails are delayed by hours or days instead of sending immediately
  • Notifications work initially but stop functioning after a plugin update
  • Only some notifications send while others are skipped
  • System shows "Not Sent Yet" status despite emails actually being delivered

Why Post Notifications Fail to Send

Several factors can disrupt MailPoet's post notification system:

1. Cron Job Configuration Issues

The most common cause involves how MailPoet handles scheduled tasks. MailPoet relies on WordPress cron jobs to trigger notifications. If your site doesn't receive regular traffic, scheduled tasks may not execute properly.

2. Timezone Conflicts

Discrepancies between your WordPress timezone setting, server timezone, and MailPoet's scheduling can cause notifications to send at unexpected times or not at all. This is particularly noticeable when daylight saving time changes occur.

3. Plugin Conflicts or Update Issues

Some users report notification problems after specific MailPoet updates. Plugin conflicts with themes or other plugins can also interfere with notification triggers.

4. Content Availability Problems

Post notifications require available content to send. If your notification is configured to show posts from a specific time period but no new content exists, the notification may be automatically canceled.

Step-by-Step Troubleshooting Solutions

Solution 1: Adjust Your Task Scheduler Method

Try switching between MailPoet's task scheduler options:

  1. Navigate to MailPoet > Settings > Advanced
  2. Locate the "Newsletter task scheduler" option
  3. Switch to "WordPress built-in cron" if using another method, or vice versa
  4. Save changes and test with a new post

Solution 2: Verify Timezone Settings

Ensure all time-related settings are consistent:

  1. Check your WordPress timezone under Settings > General
  2. Confirm your web server's timezone matches your WordPress setting
  3. Verify that any daylight saving time adjustments are accounted for

Solution 3: Check for Plugin Conflicts

Temporarily disable other plugins to identify potential conflicts:

  1. Deactivate all plugins except MailPoet
  2. Test if post notifications work correctly
  3. Reactivate plugins one by one, testing after each activation
  4. If notifications break after activating a specific plugin, you've found the conflict

Solution 4: Review System Status

MailPoet's System Status page provides valuable diagnostic information:

  1. Go to MailPoet > Help > System Status
  2. Check for any error messages or warnings
  3. Ensure all MailPoet components show as connected and functioning
  4. Review the task scheduler connection status

Solution 5: Test Content Configuration

Verify your post notification settings match your content strategy:

  1. Ensure you're creating truly new posts rather than updating or republishing existing content
  2. Check that your notification is configured to pull from the correct categories
  3. Confirm the "send immediately" option is selected if you want instant notifications
  4. Test with a clearly new post to eliminate content-related issues

When to Seek Additional Help

If these solutions don't resolve your post notification issues, consider these additional steps:

  • Check the MailPoet knowledge base for updated troubleshooting articles
  • Review your web server's error logs for related messages
  • Ensure your WordPress installation and all plugins are updated to their latest versions
  • Consult with your web hosting provider about cron job configuration

Post notification issues can be frustrating, but they're often resolvable with systematic troubleshooting. By methodically testing each potential cause, most users can restore reliable automatic notifications for their subscribers.
