Image Size Too Small in Tableau Subscription Emails

In order to see the view in the Tableau subscription email properly, the solution is to set the Dashboard to 'Custom size'.  The following includes additional details on turning off the Automatic Dashboard size and another workaround to use a PDF.

Option 1

In Tableau Desktop, specify a dashboard size instead of using Automatic Dashboard sizing. For more information, see Size and Layout Your Dashboard in Tableau Help. If this does not work for users who are looking at the dashboard in real time on Tableau Server, specify a specific view for Desktop (or other device) clients. 

Note: When the workbook is published, the layout that is active in the dashboard when it is saved is the one that Tableau Server will use when generating a subscription .png file. Keep that in mind when saving work on the dashboard to prevent the wrong view layout from being used in subscription emails.

Option 2

Instead of subscribing, export the view as a PDF using the tabcmd export command. For more information, see tabcmd Examples and tabcmd Commands in Tableau Product Help.
