How to retrieve Email Header information

E-mails are made up of two parts: the header and the message body of the email. Every email you send or receive contains a header which provides a detailed log of the network path taken by the message between the mail sender and the mail receiver(s) (email servers).

Your email client program (Outlook, Gmail etc…)  will usually hide the full header or display only some information such as From, To, Date, and Subject. Below you’ll find ways to retrieve the full header information from an email using various popular email clients.

When reporting spam, hacking, phishing or spoofing, it is essential that we receive the full email header information in order to troubleshoot mail delivery problems. If you are receiving bounce backs when you try to send email, the email header information is also helpful to the HostPapa support team.
