A brief of idea
With nearly 100,000 different custom extensions both free and paid available in Google Chrome’s marketplace, there’s a huge opportunity for creating a useful extension for people to use while browsing the web as a low effort business idea. One of my favorite Chrome extensions, Yet Another Mail Merge, which enables you to send bulk customized emails from within Gmail, gives you 50 free credits to send emails and gives you the chance to upgrade to a paid account to unlock more sending—a great upsell for the people who are getting value from the extension.
