Promote your lead magnet on social media.

Pop-ups are a great idea and a popular choice. Pop-ups can be set to only occur once per visitor so that they aren't interrupted and annoyed.

For example, you can use HelloBar to place an email sign-up on the top or bottom of your website.

In your signature line, mention your lead magnet.

Ask your subscribers to share with other people who might be interested in reading your content. Then, with time they can sign up for your mailing list.

Conclusion

An email list is the best marketing tool for your home-based business. It will give you the most value for your money, so make sure it's part of your marketing plan. A great lead magnet is the key to success.
