When adjusting your Custom Email options, you will need to know the recommended image sizes. Here is a guide to help:
Email Logo (for both Queue and Welcome emails): 575 x 150 pixels
Web App Logo: 456 x 194 pixels
For best representation in Outlook, it's recommended that you save your images at 96 dpi resolution.
Once you have the correct size images on hand, you can find more information on how to customize your template here.
