Use Earn.com to make money online by replying to emails and completing tasks. It works on your phone, in any country, with no need for a bank account.
We’re excited to announce that 21.co is now Earn.com!
Our product is unchanged: you still earn digital currency for replying to emails and completing tasks, and you can still earn tokens for signing up for our token launch later this year. But we think “Earn.com” gets that concept across more quickly than “21.co”, especially to folks who are new to digital currency.
The idea behind Earn.com is that we’ve built a positive-sum social network, where every notification is an opportunity to earn money. This is quite different from existing social networks, where notifications are often distracting or even downright negative.
Rather than posting something and hoping other people will like it, at Earn.com you complete tasks and reply to messages that others have paid to send. It’s a positive-sum system where everyone comes out ahead, and where progress is measured in the value created for you and others. It’s also an important practical application of blockchain technology — rather than mining or buying digital currency, now you can earn it at Earn.com. That started with earning Bitcoin — and we’ll continue to support Bitcoin — but we’ll be adding ways to earn other digital currencies as well, starting with our token.
How to make money at Earn.com
You can think of Earn.com as a two-sided marketplace with two different kinds of accounts: users and senders.
For users, Earn.com is very simple — just set up a LinkedIn-style public profile, join lists, and link your Gmail account. Then start getting paid tasks based on your skills and interests. Specifically, there are several ways to earn:
Create a public profile to receive paid messages
Join lists to receive more paid messages
Use an autoresponder to get people outside your network to pay for email replies
Refer verified users and senders (request beta access at support@earn.com)
Sign up and get verified to get issued tokens in our token launch
Roughly speaking, the higher your skill level and the heavier your daily email volume, the more opportunities you have to earn.
How to send tasks and messages at Earn.com
For senders, Earn.com is a replacement for InMail, a product that allows a sender to pay LinkedIn to cold email someone with a LinkedIn profile.
From the sender’s vantage point, Earn.com has three advantages over LinkedIn InMail:
Recipients get paid, which gives them an incentive to reply
Senders can easily send mass messages rather than clicking on thousands of profiles
Senders can retarget users and send complex tasks like surveys, rather than just sending plain text emails
Empirically, we find that Earn.com senders get response rates >30% within 24 hours for $1 incentives, and >70% within 24 hours given $10 incentives. This holds true even for messages with many thousands of recipients, and is extraordinarily high relative to the 1.7% response rates for typical cold emails. As such, any business that sends cold email or conducts surveys can benefit from Earn.com.
What the new domain means for 21.co users
Here’s what the new Earn.com domain means for existing and new 21.co users alike:
Effective immediately, Earn.com is the new canonical URL, company, and app name.
In particular, to find our app in the App Store or Google Play you can just search for “Earn.com”
All profile and list URLs (like 21.co/bhorowitz) will be redirected in perpetuity to their analogs at Earn.com (such as earn.com/bhorowitz). So don’t worry if you’ve linked to your 21.co profile page from your Twitter, LinkedIn, or homepage — that link will continue to work in perpetuity, and you can update it to the corresponding Earn.com link at your convenience.
Our token launch remains on schedule for later this year. You can read more about it at earn.com/token.
Our logo has been updated. Other website assets remain the same for now, though we may do a refresh in the future.
We have discontinued some older URLs, but our open source python libraries will continue to remain available.
Our 21.co corporate email addresses will continue to work in perpetuity. This includes our support emails. So support@21.co will work, but you can use support@earn.com going forward.
Our Bitcoin Fees and Bitnodes services will now be canonically hosted at bitcoinfees.earn.com and bitnodes.earn.com respectively. You can still access them via bitcoinfees.21.co and bitnodes.21.co — though there will be the slight overhead of a 301 redirect, so you should update to the earn.com versions of the URLs for maximum performance.
Our blog is at news.earn.com, though news.21.co links will continue to work.
Our handle across social media is 
Twitter: twitter.com/earndotcom
Facebook (announcements page): facebook.com/earndotcom
Facebook (community group): facebook.com/groups/earndotcom
AngelList: angel.co/earndotcom
Conclusion
The Earn.com name makes it obvious that the purpose of our web and mobile apps is to make it easy for users to earn money online.
That starts with simple things, like getting paid to respond to emails or fill out surveys. Eventually, if we’re successful, Earn.com will make it possible for anyone, anywhere in the world to pick up a phone and start earning money from a stream of personalized, paid tasks.
Today, you can use Earn.com to earn Bitcoin —and we’ll continue to support that crucial use case — but soon it’ll mean the opportunity to earn the digital currency of your choice, beginning with our new token.
Why another new token? The short answer is that this token differs from others in that you don’t have to buy it in an ICO — you just earn it. And it gets more scarce as more users earn it, because the number of tokens issued halves every time the userbase doubles. In particular, if you sign up to earn.com and get verified now, when the earnable token launch occurs you’ll be grandfathered and will get some tokens for free. So learn more here and at earn.com/token, and then sign up at Earn.com!
