Within Teamwork Desk, you can edit an email
    signature of an individual inbox.
Note: Inbox settings
            can only be managed by site
            administrators and inbox
                administrators of the
            inbox.
Click your profile icon to the top
        right of the navigation bar and select Settings from the dropdown
        menu.

In the settings area, select the Inboxes tab.

Choose the inbox you would like to make
        changes to and then select Edit
            Inbox from the left pane.

Hover over
        the Email Signature section and
        select the pencil icon to add or edit an
        inbox signature. 

If there are multiple users replying from
        the same inbox, you can use
        variables to insert details to your
        ticket replies, such as the agent's name. 
You can insert a variable into the email
    signature by clicking the Insert
        Variable option in the text
    editor toolbar. Once you select a variable
    from the dropdown, it will be added to the
    text area.

If you want to add an image to your signature
    you can simply drag the image from your
    computer into position in the signature text
    area.

Alternatively, If you want to use an image
    stored online you can use the image URL and
    paste it into the source within the
    editor.
Click the View Source button ( 
<
  > icon) on the left
    of the editor bar and paste your URL in the
    image source code.
The highlighted area above shows the pasted
    URL. You can follow the basic HTML below to
    insert your own.
<img
                src="your image
                URL"> - replace
        "your image
            URL" with the image URL that you
        want
        to use.
