How many email newsletters are you bombarded with every single day? There’s a reason for that. Email marketing to an actively interested group of email subscribers is one of the best ways to make money online. There have even been million-dollar businesses built from simple email newsletters like TheSkimm, or Mister Spoils. Each newsletter targets a specific type of user with interesting, daily content, while also partnering with relevant companies and affiliates to bring in extra money. If this seems daunting, it’s not. Email marketing tools like MailChimp, ConvertKit, HubSpot and AWeber make it easier than ever to get started with email marketing. Here's my comparison of ConvertKit vs AWeber vs Mailchimp to review a few of my top picks. And another great option to consider (with the largest free plan available) is SendPulse, with their ability to send up to 15,000 emails per month to 2,500 subscribers, and then affordable plans starting at under $10/month as you grow from there.

This will help your listing show up in keyword searches, and you are more likely to sell something if the buyer knows a lot about what they are looking at.

It's not as glamorous as owning your own product, but I think it gets much closer to the idea of passive income. Check out how affiliate marketing creates passive income better than any other type of business.
High-ticket consulting or coaching: You could sell your own high-ticket consulting or coaching products from your website. You'll still need a website, merchant account, sales funnel, lead magnet and many other items. But you can easily earn a substantial amount of money from each individual customer, making it well worth the arduous setup required.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt).
