Postmark allows you to export a list of all your messages (including bounces) in a CSV file. The CSV file is limited to 500 records. To export more than 500 records, use our Messages API for retrieving messages in JSON format.
Export bounces through the UI
Use the date filter to limit the number of results (default is set to All time) and Filters to retrieve the specific bounce type you want. After filtering your desired search, select Export.
You can use the
Suppressions API to pull a Message Stream's suppressed recipients along with their suppression reason (
ManualSuppression). Or, use the Subscription Change Webhook to be immediately alerted anytime a recipient is added or removed from a Message Stream's Suppression list.
You can also use the Bounce API to get a list of all bounces that have occurred in the past 45 days programmatically or use a Bounce webhook to get immediate notifications as JSON, each time a bounce occurs within a Transactional Message Stream.
