A few days ago I wrote a article explaining that the famous Avast antivirus in its free version collects your internet traffic and sells it through a bridge company to large companies such as Google or Pepsi. The idea is clear. You create a good application, you make it free, and when you have it installed on millions of devices, you collect information from your users and sell it to third parties.
It seems that Edison Mail does the same, both in its versions of iOS and iPadOS and in macOS. In the end, we will have to think badly of any application that is not paid. The company that comes up to you and tells you that its software is worth as much, either as a one-time purchase or as a monthly subscription, will always be better than another that gives it to you and then sells your private information to third parties.
Two years after it was discovered that Google allows other companies to read emails from users' gmail accounts, it is discovered that there are other applications that do the same when handling emails.
The best known is Edison Mail, a famous mail client for both iOS, iPadOS or macOS. It has a good interface and powerful features that make it a good email manager, and it's free.
Has functions that save user timesuch as providing one-click buttons for users who submit most frequently, or requesting complete and appropriate responses automatically. This is done by analyzing the content of the email. The company then uses the collected data and sells it to third parties.
According to an investigation carried out by Motherboard, the Edison Mail company sells user information to finance, travel and e-commerce companies. Edison has not responded to the Motherboard article, but after its publication, he has provided some explanations in his blog.
He says that in order to keep his email application free and not insert annoying advertising in it, he admits that he extracts information from his users' emails, but always anonymously to study "market trends." Other mail managers like Slice and Cleanfox also use the same way of financing themselves.
