I recently received an email which was an important one, but very annoying to read.
I’m talking about non-standard, malformatted email. HTML formatted email, email with lines longer than 80 characters. To put it simply; Don’t do it. It’s evil.
There are simple rules to make your email messages useful.
When replying, please reply to the bottom of the original message. It's makes following conversations a lot easier.
If your email client doesn’t allow you to wrap lines or use only plain text, don’t use the client. Use something else, it’s not like you don’t have a choice. Personally my recommendation is Mutt. If you want something more graphical try Mozilla Thunderbird. Or try to fix your favorite client settings.
Well, for the 80 characters limit per line, that’s just the best width for a human to read. Plain text formatting is the best choice because it takes less bandwidth, it’s readable with any email client and it’s universal. It’s the same thing with attachments, if you’re using a proprietary format I might not be able to open it. Even if I could open it, I might not want to because of viruses. A good subject is also very important so that the email does not get eaten by the spam filter. If I ever need to find your email later on, a good subject helps me to find it.
