Overview

Most of their emails seem to targeted at a fairly broad audience (no surprise, as it's probably a broad audience reading them). They tend to remind readers on how great they are, how great the party is, and occasionally how rubbish the others are. There was one nice email targeted at the real Tory supporters that had 10 ideas on how people can help, from ringing voters to downloading posters.

I'm sure some of the emails were planned in advance, but the majority of them seemed very fresh and current with references to events that had happened the previous day. Overall though, they didn't stray too far from the Leaders Debate schpeel.

Every email they sent has:

• A pretty consistant look. With the same blue Conservative header, it's really clear what it is the moment you open the email
• At least 3 or 4 links in the body of the email, out to their website, some video content or some blog
• Links to their Twitter, Facebook and Youtube pages in the footer
• A request for a donation
• A few images dotted throughout the text
• They all signed off with their full name and job title. Good job too — I haven't heard of half of these jokers
• A graphic of the senders' signiture. A nice attempt to make it seem more personable... though my first reaction was to right-click, Save As. You never know when those might come in handy

The only persons' emails that didn't have all of these things were David Cameron's. Mind you — he is the boss — he can do what he likes.

Oh, and for anyone interested, they used cheetahmail.com.
