The free plan allows one user to send secure messages with secure file attachments up to 15MB. You invent the password and deliver it to the recipient using a different secure method, not email. Your message and file attachments are protected by strong AES-256 bit encryption and your secret password. No registration is required to use Lockbin. Use Lockbin to obscure the content of your message and avoid these hazards to your privacy. Network sniffers can also spy on your email traffic while in transit. Lockbin ends message persistence, which means your email message will not be backed up on email servers or stored in backup files. Lockbin is a free web application for sending private email messages and files. Paid plans are also available that provide additional storage, unlimited email aliases, dedicated technical support, and desktop access. It uses standards-compliant encryption and provides mobile access (Android, iPhone, BlackBerry, etc.). Hushmail is a secure web-based free email service that looks and feels just like any other web-mail site, but adds strong encryption to your emails to protect your secrets from prying eyes. This means only your recipients can decode the message data. Sendinc does not save a copy of your recipients’ encryption keys and your message can not be decrypted without the key – not even by Sendinc.

Messages are encrypted with a powerful randomly-generated encryption key that is emailed to your recipients in the form of a link. Sendinc further ensures the safety of your messages by verifying your recipients are in fact your intended recipients. At no point in the process is your message data transmitted or stored in an unencrypted format. Sendinc secures your message by ensuring that your data remains encrypted from the time it leaves your computer through the time your recipients retrieve it.

You and your recipients can use Sendinc for free. Sendinc is a web-based service that makes it safe and simple to transmit sensitive information via email. Send encrypted email from your current email address (10 free messages allowed per month) and automatically receive a Registered Receipt™ record proving encrypted delivery and compliance with open tracking.

RMail allows you to easily send emails with end-to-end security and compliance.
