Email bounce notifications for changelog deliverability tracking

Problem When we send changelog updates to our customers, we currently see an overview of emails sent but receive no information about bounced or undeliverable emails. This creates blind spots in customer communication and prevents proactive support. Proposed Solution Add email bounce tracking and notifications to user accounts, showing: Which emails bounced/failed delivery Bounce reason (e.g., invalid address, mailbox full, domain issues) List of affected users per changelog notification Delivery status overview per changelog update Use Case This would allow us to: Identify customers with email delivery issues Proactively reach out to update contact information Maintain accurate customer communication channels Track actual reach vs. intended reach for product updates Expected Outcome Better visibility into email deliverability and improved customer communication reliability.
