You can create text-only marketing emails. In fact, they sometimes perform better than HTML emails. Here are a few tips if you want to test the waters: [*]Restrict the line length to 60 characters [*] [*]Be concise, limiting copy to 100 words or less is generally advised [*] [*]Place links on their own lines to improve readability [*] [*]Justify text to the left margin [*] [*]Use caps and special characters to highlight text and separate sections of the email since formatting options are limited [*] [*]Don't place periods or other punctuation marks immediately after a URL link since that may impact redirection [*] [*]Use white space around paragraphs http://www.quora.com
