Kate's take, in a sentence or two

Kate says that for bundles and summits, she always recommends going low ticket rather than high ticket, since the goal is to stand out among many offers, give people a fast quick win, and turn leads into buyers later—not to showcase your priciest course that most people won't act on. For sponsored emails, though, her strategy is always to offer a freebie rather than a paid product, because a freebie captures opt-ins from everyone interested (not just buyers), letting her build her email list and follow up with a tripwire funnel—which ultimately makes more money and grows her list, whereas sending people straight to a paid offer in an email doesn't convert well and leaves her with no way to follow up.
