Message Activity Log

The Message Activity Log gives you the opportunity to see any messages (especially error messages) associated with your campaigns and sends.

You can see API campaign transactions, troubleshoot details on failed messages, and gather insight on how to improve notification delivery or solve existing technical issues.

To access the log, go to Settings > Message Activity Log.

You can filter by the following content logged in the Message Activity Log:

• Push notification errors
• Aborted message errors
• Webhook errors
• Mail errors
• API message records
• Connected Content errors
• REST API connected audience errors
• User aliasing errors
• A/B testing errors
• SMS/MMS errors

These messages can come from our own system, your apps or platforms, or our third-party partners. This can result in an infinite number of messages that can appear in this log.

Understanding log messages

To determine what your messages mean, pay attention to the wording of each message and the columns that correspond with it, as it can help you troubleshoot using context clues.

For example, if you have a log entry whose message states “empty-cart_app” and you aren’t sure what that means, look to the left at the Type column. If you see “Aborted Message Error”, you can safely assume the message was what was written as the abort message using Liquid, and that the message was aborted because the intended recipient of the message had an empty cart in your app.

Common messages

There are some common message types you might see, and some might even provide troubleshooting links to help you diagnose and fix issues.

The following messages listed are for example purposes and may not exactly match what is displayed in your log’s Message column.

Message Type	Potential Message	Description
Soft Bounce	The email address [email protected] soft bounced.	The email address was valid and the email message reached the recipient’s mail server, but was rejected for a “temporary” issue. Common soft bounce reasons include: The mailbox was full (the user is over their quota) The server was down The message was too large for the recipient’s inbox If an email has received a soft bounce, we will usually retry within a 72 hour period, but the number of retry attempts varies from receiver to receiver.
Hard Bounce	The email account that you tried to reach does not exist. Try double-checking the recipient’s email address for typos or unnecessary spaces.	Your message never reached this person’s inbox because there was no inbox to reach. If you want to dig further in, messages like this can sometimes have links in the View Details column that will allow you to view the intended recipient’s profile.
Block	Spam message is rejected because of anti-spam policy.	Your message got categorized as spam. This mail error is logged for a user if we’ve received an event from the ESP indicating the email was dropped. It might just might be for that intended recipient, but if you’re seeing this message a lot, you might want to re-evaluate your send habits or the content of your message. Also, think back—did you warm up your IP? If not, reach out to Braze for advice on getting this going.
Aborted Message Error	empty-cart_web	If you have an app with a cart or you create a send with an abort message in the Liquid, you can customize what message is returned to you if the send is aborted. In this case, the message returned is empty-cart_web.

Why isn’t my message listed here?

The messages in the Message Activity Log can come from a variety of sources: Braze, your apps or platforms, or our third-party partners. This means there is an infinite number of messages that could possibly appear in this log—as you can imagine, we can’t list them all!

For example, some potential “Block” messages, in addition to the one listed in the preceding table, could be:

• Unfortunately, messages from [IP_ADDRESS] weren’t sent. Please contact your Internet Service provider since part of their network is on our block list.
• Message rejected due to local policy.
• The message was blocked by the receiver as spam.
• Service unavailable, Client host [IP_ADDRESS] blocked using Spamhaus.
