Finding a site with all the latest tips on secure email reading is a good idea. Once you read them, actually paying attention is probably better.
The single most important thing you can do is to make sure that your email reader does not run any scripts it finds in an HTML email. The single most secure thing you can do is to find an email reader that won't render HTML, but rather shows you the text, then pick out the message from that. As far as I'm concerned, unless you have state secrets on your computer that's about as sensible clutching a shot gun when you open the doors to little girls selling cookies, but hey, that's just me.
Make sure that your email reader will show you a link address when you hover over it. Then distrust any email that has a link that doesn't match the text. One common spam thing to do is to show a decoy link as text, while the real link sends you off to some malware site.
One spam that I've been getting recently (and repeatedly!) is purportedly from the CEO of some insurance company, telling me that they've looked at my resume and I'm ideal for them. The insurance company is real, the links are fake, and it would take a lot of convincing to make me believe that an insurance company has a need for a circuit designer, an embedded software engineer, someone facile with digital signal processing, or an expert in control systems, which is about the extent of what I can claim as professional expertise.
