Q: What are the proper dimensions (specs) for an email template?
A: All Swiftpage email templates are 600 pixels wide. (If you are importing a template, the recommended width is 600 pixels.) This is the average viewing capacity of most email programs. The email can be as long vertically as you want, but you may not have more than 23 Swift windows in either column.
All Swiftpage email templates have two columns. You can resize the left-hand or right-hand column as wide as 580 pixels, which essentially reduces the other column to an unusable size (about 8 pixels wide, because there is a standard 12 pixel space between the two columns).
Header images imported into Swiftpage should be 600 pixels wide. All other images imported into Swiftpage should be no more than 50 kb large, no wider than 580 pixels, and no more than 72 dpi in resolution.
