This article explains when and how to use the #debug feature. ## What is a #debug email? A #debug email is a diagnostic tool that flags a specific mail flow event in the Opensense backend for engineering review. Including `#debug` followed by 5 random digits in the subject line creates a unique identifier that allows the engineering team to locate your exact mail flow event and gather detailed technical data tied to it. ## When to send a #debug email Send a #debug email when you encounter any of the following signature issues: - **Missing signatures** - A user's signature is not appearing at all - **Incorrect signatures** - The wrong signature is being applied - **Placement problems** - The signature is appearing in the wrong location while composing - **Formatting issues** - Signature elements are misaligned, distorted, or displaying incorrectly - **Wrong signature data** - Incorrect information such as name, title, or contact details appearing in a signature ## How to send a #debug email **Subject line format:** `#debug` followed by any 5 random digits — for example, `#debug 67890`. This is what flags the email for diagnostic review. You must compose a new email — do not reply to or forward an existing message. ### Step 1: Compose a new email to Opensense support Open your email client and compose a new message — do not reply or forward. 1. Address the email to [help@opensense.com](mailto:help@opensense.com) 2. In the subject line, type `#debug` followed by a space and any 5 random digits (e.g., `#debug 67890`) 3. In the body, include the details listed in Step 2 below 4. Send the email The #debug flag only works when sent from the affected user's mailbox, using the email client where the issue is occurring. Sending it from a different account or client will not capture the relevant diagnostic data. ### Step 2: Include these details in the email body The more context you provide, the faster support can diagnose the issue. Include the following in the body of your #debug email: - **Email type** - Is the issue happening on new emails, replies, or forwards? - **Email client and device** - Which platform and device was used (e.g., Outlook on Windows, Gmail on Chrome, Apple Mail on iPhone)? - **Affected users** - Names or email addresses of users experiencing the issue - **Timeline** - When the issue was first noticed ### Step 3: Wait for a support response Once received, the Opensense engineering team will use the diagnostic data tied to your #debug email to investigate and follow up with findings or next steps. ## Related articles - [Signature Management & Deployment FAQ](https://help.opensense.com/v1/docs/frequently-asked-questions-1)
