Ghostmail will no longer provide secure email services unless you are an enterprise client.
According to the company, it is "simply not worth the risk."
In an email to customers and posted on the secure email provider's website, Ghostmail said, "the world has changed for the worse, and we do not want to take the risk of supplying our extremely secure service to the wrong people."
In addition, while Ghostmail still believes the average user has a right to privacy, a "strategic decision" has been made to shift Ghostmail services exclusively to the enterprise sector.
"We hope you understand this decision and we refer to other free services available," Ghostmail said.
Ghostmail, located in Switzerland, says the service offers a "significantly" more secure and private, encrypted environment than most online service providers. In the Ghostmail FAQ, the company says that it keeps email secure through 256-bit AES encryption and RSA 2048-bit key cryptography -- granting only the user access to their data and private keys, allow anonymous signup and "as little metadata" storage as possible.
Alternative email providers include Tutanota and ProtonMail. For an in-depth discussion on these services, you can check out a current debate on Reddit.
The service will be closed down on September 1, and users of the Ghostmail Pro service will be contacted directly for refunds.
