You can build an email list without a free gift, but you need something else that makes people want to give you their email address. That could be a newsletter with genuinely useful information, early access to something, or a promise of content they cannot easily find elsewhere. The free gift, which is called a lead magnet in marketing, became popular because it works quickly. Without one, growth tends to be slower, but the people who do sign up are usually more interested and more likely to stay. Can a business build a loyal email list without using incentives, or does something always need to be offered?
