Using Quora to collect emails can work well if you focus on helping people first. Start by answering questions related to your niche. For example, if you're promoting a fitness product, look for questions about weight loss or home workouts. Write clear and helpful answers that give real value. At the end of your answer, you can mention a free resource—like a short guide or tool—that helps even more. Then you link to your landing page where they can sign up with their email to get it. The key is to make sure the link feels like a natural next step, not just a promotion. Also, it helps if your Quora profile is filled out properly with a short bio so people know who the advice is coming from. Over time, if your answers get views, more people can discover your email list. What type of questions do you think would be good to start with on Quora?
