Nearly a year ago I decided to divest myself of Google as much as possible, partially for the usual privacy concerns, but mainly I was concerned that too much of my life was tied up in a free service whose customer service is nearly nonexistent; if somehow my Google account got borked I had no recourse. So I decided to switch to paid services wherever I felt the service offered was valuable enough. Email was one of them, and I've been very happy with Fastmail ever since I've switched. They offer all the usual protocols, have a webmail interface every bit as good as Gmail's (including fast search with a rich query language), and a whole bunch of other features I'll never use but I'm glad exist. Also, the one time I needed customer service, it existed.

My one quibble with their webmail client is there's no way that I've found (maybe it's hidden somewhere) for plaintext emails to render in a monospace font. I get a lot of diffs via email where monospace is important for legibility, and frankly I kind of find monospace more readable in general, although I know that assertion is provably false.

All this is going a long way around showing off a small CSS hack to get plaintext email rendering and composition to be done in a monospace font in Fastmail's web client. I used Stylish for Google Chrome, but pretty much any CSS-hacking extension of your browser of choice should work:

@-moz-document url-prefix("https://www.fastmail.fm/mail") {
  .message pre {
    font-family: monospace;
  }

  .TextView textarea {
    font-family: monospace;
  }
}

The snippet is also in a gist or you could install it directly into Stylish from userstyles.org

In closing, you should put two spaces after a period. drops mic
