Image Size Too Small in Subscription Emails

Issue

When you have subscribed to a view, images of views in subscription emails are too small to read.

Environment

  • Tableau Server
  • Tableau Online

Resolution

Use one of the following workarounds.

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.

Cause

The underlying logic of each email client determines how images are displayed in the email application. Tableau Server and Tableau Online have no control over how each email application renders emails.

Whenever the default size is set to 'fixed', the subscription image is set to 800 x 600 px. These  set measurements are responsible for the distorted visualizations due to objects not fitting properly. The solution is to set the Dashboard to 'Custom size'.
