## Google platforms

Follow these steps to find detailed header information for messages in Gmail:

1. Log in to your Gmail account.
2. Find the message whose details you want to download and open it.
3. Click the three dots at the top-right of the message pane and select **Show original**.
   <img
     src="/_images/google/gmail-show-original.png"
     alt="A close-up of the Gmail interface. The options menu for a message is expanded, and 'Show original' is highlighted."
     style="height:500px;"
   />
4. Copy the entire raw message and save it in a text file.

You can now send the text file containing the raw message information to Nylas.
