The procedure is:

  3. Pay the _exact_ amount of BTC to the given account.

Your message will be part of the block-chain within few blocks, which means instantly thousands of copies all around the globe forever.

  • No registration required.
  • Totally anonymous if wanted.
  • Open protocol and basic python tools are included.
  • Offline option.
  • Client is signed to verify authenticity.

Basic technical details:
The clients are html+css+javascript only, and they are enough to read the messages forever (you can save the client locally for offline use).
The service for writing new messages requires the availability of an appropriate server, but the already processed messages are accessible forever, and some are already present on your copy of the block chain.
In order to write a new message, the clients create an email request which the server then processes.
The server is a special customised bitcoin setup behind tor.
