GlockApps tracks these types of bounce messages from Mailgun: hard bounces, dropped messages, unsubscribes and spam complaints.

Navigate to Bounce Monitor -> Analytics to view the bounce data by sender domains and email addresses.

Under "Live Feed" you have an aggregate report about all bounce emails.

You can export the bounces from your GlockApps account and load them into the suppression list in your email system so the next time you shoot a campaign to the same list they will be excluded.

GlockApps stores bounce emails and analytics for three months. Data that is older than the 3-month period from the actual date is automatically deleted.

Receive Alerts about Bounce Emails

The Bounce Monitor can send you email alerts when the number of bounce emails reaches or exceeds the values specified by you. It helps you identify the peaks of bounce emails and understand which email campaigns generated the highest bounce rate.

A lot of delivery services will suspend the user’s account if the bounce rate exceeds the threshold (the industry average value is 10%). With the Bounce Monitor alerts, you will be proactively informed when the quantity of your bounce messages is reaching the allowed threshold.

You can activate the sending of the alerts in the Bounce Monitor Settings.

Fill in the fields:

Alert email – enter the email address to receive the alerts.

Alert interval – choose the interval to send email alerts (from 5 minutes to 24 hours)

Be aware that if you set a short interval when receiving a high number of bounce emails, you will be getting a lot of email alerts from the GlockApps Bounce Monitor.
