It doesn’t have to be complicated – just text, colours, graphics and such. The most important step is to create a signature using whatever HTML editor you prefer. Step 2: Edit Your Signature in a HTML Editor In this example, we’ll just use the Chris Writes website address and an image copied from the site. This is the easy part – you need to decide what information you want to display on your signature, for example your name and phone number, company address and perhaps a logo. You need access to a web host or DropBox to store your signature’s images.You should be familiar with the basics of HTML if you want to create something a little more complex.You should have a HTML editor such as Dreamweaver, Sandvox, etc.We’ll look at how to use Mail’s templates in another tutorial, which is a slightly different way of achieving similar results. This tutorial describes how to create cool HTML-based custom signatures that can include images and more exciting text than is possible in standard signatures. It’s not easy to make a signature stand out if you use the signature editor within Mail. Its signature editor contains just a very simple text entry field where you can type characters and highlight them as bold, italic or underlined, but there aren’t many more options than that. Mac OS’s Mail app has never made it especially easy to create customised signatures.
