Add possibility to opt to NOT include profile picture in emails by default

The current default is to include profile picture in emails sent from workspaces. It would be nice to have the option to not include it by default.

Hi, yes it would be great if you could add the option to not include the profile picture in emails by default. We never send any emails with our profile pictures so now we remove it every time we write a new email. 

If such a setting would be implemented, would it be in: 
- personal level (in all workspaces)
- workspace level (for all admin in that workspace)
- customership level (for all workspaces)
