HTML Email button link not working

I am trying to create a button in an HTML email that goes to a link in a href tag. I have practically no understanding of html code to be honest. This is what I'm trying:

<p>
  <input style="width: 200px; padding: 15px; box-shadow: 6px 6px 5px; 
    font-weight: MEDIUM; background: #3ebfac; color: #000000; 
    cursor: pointer; border-radius: 10px; border: 1px solid #D9D9D9; 
    font-size: 110%;" onclick="window.location= a href=[SURVEYURL]" 
    type="submit" value="START NOW" />
</p>

The link doesn't seem to work...

Please let me know if you can help?

Thanks.

Alex.

Solution

You will never get JavaScript to run in an email for obvious security reasons. Also no need to use a submit button which will attempt to submit a non-existing form.

This will work better - the anchor is allowed in emails

<p>
<a href="[SURVEYURL]" style="text-decoration:none;
    width: 200px; padding: 15px; box-shadow: 6px 6px 5px; 
    font-weight: MEDIUM; background: #3ebfac; color: #000000; 
    cursor: pointer; border-radius: 10px; border: 1px solid #D9D9D9; 
    font-size: 110%;">START NOW</a>
</p>
