But here is something you should know if you want to use their platform.
They do not allow you to direct people, that click on your link in your video ad, to an opt in page.
I tried that and it doesn't work. They will reject your ad.
But what you can do is send people to a sales letter or a VSL (video sales) that links to your opt in page.
Are you using their platform? What do you think of their ad platform?
