Both web pages and emails can contain alot of text and graphics, and this sometimes makes it harder to get your subscribers to perform a certain task, such as clicking on a link to see your special offers.

Numerous research papers tell us that the majority of Internet users respond better to a plain, bold, blue text link -- such as this -- as opposed to a banner or button. So, if you're going to include links in your emails, make sure they are bold, blue and underlined. This will mean that more subscribers click through, meaning more conversions/sales for you.
