Qualifying leads before adding them to your list helps make sure you’re not just collecting emails, but people who are actually interested in what you offer. A good way to do this is by using simple pre-qualification steps on your opt-in form. For example, ask one or two short questions that show their interest level. You could also offer something specific that only your target audience would want, like a free guide that relates closely to your affiliate offer. If someone signs up for that, it shows they’re likely interested. You don’t need to collect too much information, just enough to know they’re the right fit. Adding unqualified leads can reduce engagement and hurt your deliverability, so it’s better to focus on quality. Have you come across any other methods that help filter out uninterested people?
