[html] Adding a 'share by email' link to website

I have an HMTL / CSS website built in Dreamweaver CS4 and I would like to add a 'share by email' link to the site (so that anyone who clicks on it can easily send a link to the site to their chosen recipient). I would like one of those envelope icons, but preferably customisable in size so it would fit nicely with other icons I have.

Please could someone kindly advise me as to what is the easiest way of doing this - I am a beginner. Thanks in advance.

Best? Well. probably not, But If you don't want to design something bespoke this is the best there is...

<a target="_blank" title="Share this page" href="http://www.sharethis.com/share?url=[INSERT URL]&title=[INSERT TITLE]&summary=[INSERT SUMMARY]&img=[INSERT IMAGE URL]&pageInfo=%7B%22hostname%22%3A%22[INSERT DOMAIN NAME]%22%2C%22publisher%22%3A%22[INSERT PUBLISHERID]%22%7D"><img width="86" height="25" alt="Share this page" src="http://w.sharethis.com/images/share-classic.gif"></a>

Instructions

First, insert these lines wherever you want within your newsletter code. Then:

1. Change "INSERT URL" to whatever website holds the shared content.
2. Change "INSERT TITLE" to the title of the article.
3. Change "INSERT SUMMARY" to a short summary of the article.
4. Change "INSERT IMAGE URL" to an image that will be shared with the rest of the content.
5. Change "INSERT DOMAIN NAME" to your domain name.
6. Change "INSERT PUBLISHERID" to your publisher ID (if you have an account, if not, remove "[INSERT PUBLISHERID]" or sign up!)

If you are using this on an email newsletter, make sure you add our sharing buttons to the destination page. This will ensure that you get complete sharing analytics for your page. Make sure you replace "INSERT PUBLISHERID" with your own.
