Solution

We created python code to filter and find the error details (reasons) for all bounced emails in HubSpot.

The result? The main error was DKIM configuration.

To address the problem, we wrote another Python code to efficiently filter and extract error details for all bounced emails within HubSpot. By analyzing the bounce logs, we identified a recurring issue related to the DKIM configuration.
