Hi there, /r/Blind!
I'm a developer and I've been tasked with making plain-text emails. As some of you may know, when an email is sent by a company it's often delivered as two components simultaneously: an HTML version and a plain-text version. The HTML version has all of the images, colors, and styling, while the plain-text version is simply text.
There are many guides out there for making HTML email more accessible, but relatively little on making the plain-text version as friendly as possible to all readers. I'm hoping to strike a balance between being screen reader-friendly and being friendly to sighted users.
One thing I often see in plain-text emails is the use of dashes or some other character repeated across the screen to separate sections. In my testing with VoiceOver, these characters would be read as "fifteen dashes" or similar. That doesn't seem ideal. My current theory is that using capital letters to differentiate section headings is ideal, as it stands out to a sighted user but isn't read differently by the screen reader.
So, what are the things you appreciate and the things you dislike about plain-text emails? What would the ideal plain-text email be like? Am I even correct in my assumptions that the visually-impaired community uses plain-text emails, or is the default HTML email more common than I think?
Any insights you could give me would be very helpful!
