To grow a push notification list, it helps to offer something useful in exchange for permission. One good way is to give a lead magnet, like a free guide, discount, or special deal. For example, if you're promoting fitness products, you could offer a free meal plan or workout checklist. This gives people a reason to subscribe because they’re getting something helpful right away. Make sure the lead magnet matches the offer you'll promote later, so subscribers stay interested. You can also create short tips or simple downloads related to the niche you're working with. The more useful and targeted the lead magnet is, the more likely people will click “allow.” What kind of lead magnets have others seen work best for this?
