As a security enhancement to protect customer data, our CPaaS platform now masks all numeric characters in email subject lines when stored in the reports database. This means that within panel reports, downloaded reports, events APIs, and webhooks, any numbers in the subject line will appear masked (e.g., "OTP is ****12"). This does not affect the actual email delivered to end customers they will continue to see the original subject line with full numeric characters exactly as you sent it.
This masking is non-reversible and applied by default across all stored reports. Once masked, the original numeric values cannot be retrieved from any reporting interface, API, or webhook. If you need to preserve numeric data from subject lines, you should store that information in your own internal systems before sending emails through the platform.
