I'm trying to email some tabular data from Do-More, so I need the emails to appear in a monospaced font for the columns to line up. In a PC email client, you can specify the font, but in Do-More there's no such mechanism, so I'm trying to figure out how the email format does it under the hood and hopefully it's something I can embed in the email body text so it can be done from Do-More. I tried the following, based on The Google, but doesn't seem to do what I want, when viewing received emails in Thunderbird.
Anyone know how to do this?
