FAQ

Why are my emails marked as failed?

Within the Audience Activity section, you can view and export the message data with failure reasons. The two most common reasons for failed emails are:

  1. Sending to non-existant email domains. E.g [email protected] or [email protected]
  2. Sending to emails that are on your ESPs Suppression list.
  • If you are using Custom Unsubscribe Links in your emails, you will need to also unsubscribe the email address within OneSignal.
  • If you are sending to a previously bounced emails, it will be added to your ESPs Suppression list and will be marked as failed for each message going forward.

Failed emails can occur for several reasons but if you are adhering to email best practices, the number of failures should be low. See How to improve email deliverability for more details.

Why are Open events low?

Tracking email Open events isn't always 100% reliable. There are ways your users can (accidentally or purposely) block open event tracking like using strict ad filtering (uBlock origin for example), strict inbox privacy settings, or blocking requests at the network level.

If you are troubleshooting multiple email addresses, try testing on different devices and browsers connected to different networks (mobile, home, business, etc) as a way to isolate where an issue might be.

Why are Click events low?

There are few reasons why you would see low click events. Generally, it's due to certain browsers blocking these events. For example, the Brave browser blocks UTM tracking by default. Opera GX and Firefox also have settings to block UTM tracking which they recommend to users during setup.

If you have more cases reproducing this and you 100% sure that the UTMs are only for the specific campaigns, we can try to look deeper into it
