Hi,
When you edit the email, you can click on the edit icon of the template setting. You'll get a popup where you can modify the template HTML and CSS.
At the beginning, you'll have a section starting with
where you have the default CSS of the template.
So you can add your own CSS to customize the links color.
For example:
a{ color: red !important; }
Note different email clients will display your emails differently.
So more intricate CSS / HTML modifications might be necessary.
Here is a page which talks about this and potential solutions:
