Question: How to compensate for high resolution displays?

Answer: Some devices rescale your email as they have higher pixel density than traditional displays (like Retina). To compensate, you can choose to upload a larger image. If your intended image display width is 200 pixel, upload an image that is 400 pixel wide.

DPI (dots-per-inch) is not supported in PNG/GIF/JPEG images, but instead handled by the email client/web browser (defaulting to 72 DPI).
