Hyperlinks in the footer aren't visible

Hello, I have used the default footer when sending a campaign but a few subscribers have come back to say it’s not clear how to opt out or go to the personal preference page. I’ve had a look myself and I think its because they don’t visibly show as hyperlinks. Do you know how I edit this to make it more obvious? I’m new to using PHPList. Attached is a screenshot to demonstrate what I mean. You can see ‘forward this message’ is underlined but no other hyperlink is highlighted.

@Kim1 The “forward this message” link is underlined because the responsive template includes styling for that link. Other links in the campaign content are not styled.

See the “Simple responsive template” on the Manage Campaign Templates page. I guess that if you want all links to be underlined, which I think is usually an option of the browser, then you would need to include some CSS to do that.
