A method and server are provided for sending a secure message from a first computing device to a second computing device. A first computing device sends an encrypted, secure message a message server. The message server processes the secure message to unencrypt and separate the secure message contents into two or more separately downloadable message parts. The server sends a complex link to the second computing device, or sends a complex link to the first computing device for sending to the second computing device. When the complex link is selected by a user of the second computing device the server transmits a first part of the message to the second computing device. After transmitting the first part, the server then separately transmits a second part of the message to the second computing device.
