Based on Mark Brownlow’s recommendations for formatting plain text emails, we have added a recommended width background to the textarea you guys use to enter the text content for each campaign.
This makes it much easier to keep each line under the recommended 65 characters, ensuring your newsletter is easy to read in the majority of email environments.
Unfortunately background images for form elements are not supported in Safari, but it has been tested successfully in Firefox, IE and Opera on the PC and Firefox on the Mac.
