The header information in every email is consistent, so you can use it in your email client to filter or forward all GitHub notifications, or certain types of GitHub notifications.\n\n> \\[!NOTE] If you believe you're receiving notifications that don't belong to you, examine the `X-GitHub-Recipient` and `X-GitHub-Recipient-Address` headers. These headers show who the intended recipient is. Depending on your email setup, you may receive notifications intended for another user.\n\n| Header                    | Information                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   |\n| ------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| `From` address            | This address will always be `notifications@github.com`.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       |\n| `To` field                | This field connects directly to the thread.
