SFLETTER.COM

Sfletter.com has a unique protection model that makes it different from all secure email services. The message and attachments protected by Sfletter.com cannot be forwarded, edited, printed or screen captured – they stay protected after opening and reading. Besides they can be opened only on the receiver’s computer. It can be compared with a cryptex with a key that instead of using set of symbols needs a definite user device. This service is designed to protect private and corporate corre... spondence from unauthorized information use including forwarding the emails to third parties and scanning the content of mails and attachments by other email services. Sfletter.com allows to protect either attachments – files in PDF and JPEG formats (further the list of supported formats will be extended), or the entire email message. Everyone can register an account and get a free mailbox. Protected emails can be sent to any email service or client. To open a protected email a receiver needs to download a special viewer program provided for free. The opening of protected emails can be tracked by opening time and receiver's IP address.
