Create Button in Custom Email

Is there a way to create a button in a custom email? For instance, I have a hyperlink that will take them back to the website to book their appointment in several of my custom emails. I would like to instead make a button for them to click on.

I have a plugin called Max Buttons and that didn’t work.

I tried another one I saw online which put way too many spaces in-between the paragraphs.I am not super familiar with coding so am not sure how to eliminate this much space, but this was the code I used in the html.

<table width=”100%” cellspacing=”0″ cellpadding=”0″>
<tbody>
<tr>
<td>
<table cellspacing=”0″ cellpadding=”0″>
<tbody>
<tr>
<td style=”border-radius: 2px;” bgcolor=”#960a01″>
CLICK HERE
</td>
</tr>
</tbody>
</table>
</td>
</tr>
</tbody>
</table>

Do you have any tips for button usage?
