What is a simple way to make a clickable link for emails?

I want to put a link to my business at the bottom of my emails that says "MY WEBSITE" or something similar.
This is my actual website-

Assuming everyone you send your emails to can receive html emails put this at the end of your emails.

MY WEBSITE

I just emailed that to myself and my msn mail uses html, but I didn't get a link?
I did this-
MY WEBSITE

..... on the other hand, some email providers automatically change urls to clickable links. In that case, just insert the url.

It won't work that way...

    * Click on Help & Settings in the MSN Explorer menu bar.
    * Select E-mail.
    * Now, select Signature.
    * Enter your personal signature in the entry field:
MY WEBSITE
    * Click on Save Now.

alternatively, you can open Notepad, paste:
MY WEBSITE
Save As: My Signature.html
Open your MSN mail, and while composing, add the above file as an attachment.

I posted at the same time, so:

It won't work that way...

concerns previous posts.

GOOD IDEA! But,I just tried that too, but it just came out-
MY WEBSITE

It won't work that way...

    * Click on Help & Settings in the MSN Explorer menu bar.
    * Select E-mail.
    * Now, select Signature.
    * Enter your personal signature in the entry field:
MY WEBSITE
    * Click on Save Now.

alternatively, you can open Notepad, paste:
MY WEBSITE
Save As: My Signature.html
Open your MSN mail, and while composing, add the above file as an attachment.

I don't use MSN mail, so I'm not sure, how that mail settings window looks like, but maybe, when you see:

Enter your personal signature in the entry field

it'll allow you enter plain text only.
In Thunderbird, I have "Attach" button. I click on it, and then I can attach saved ".html" file.
