External Links - Open in a new browser

Does anyone know how to get external links to open a new browser in Konversion? I don't want to take people away from my shop.

I have a button that goes to an email opt-in page on my main website (the reason I use this as opposed to connecting Drip is because I have a dual-option opt-in; one button for music fans, and another button for guitarists).

So I would like for this button to open a new browser so they can sign up, but the shop page stays open.

Any help is appreciated.
