There are some good ideas here, but putting each sentence into its own paragraph makes for choppy prose. Split them out and consider each one on its own, but once each sentence is as tight as it's going to get, why not combine related ones into paragraphs?<p>The example email is, to my eye, three paragraphs:<p><pre><code> “Hey Ralph,
I’m glad to meet another fellow Quebecois and lover of
poutine last night at the meetup. If you’re in town next
week, let’s meet up. I suggest Cafe Madeline for coffee
on Tuesday at 3pm.
I’m interested to learn more about example.com and tell
you more about thoughtbot. If you haven’t already done
so, take a look at thoughtbot.com to see some of our
recent projects. Also, take a look at our playbook
(playbook.thoughtbot.com) for more detail on our
approach to building startups.
Looking forward to hearing from you.
-Rolf”</code></pre>
I still try to live by this rule, and keep it in my signature:<p><a href="http://three.sentenc.es/" rel="nofollow">http://three.sentenc.es/</a><p>Sometimes it's three paragraphs instead of three sentences, but I think that tends to work nearly as well.
