SMX and email clients

We've recently launched a free email service that allows you to send messages securely from your browser. The messages are encrypted before they leave your computer, meaning that as they travel through the Internet and email servers, they are totally confidential. You can find out more from this blog post.

The way SMX works, is it sends the encrypted message as an HTML form to your email server. The problem that arises is that some email clients will not allow HTML forms to display, for security reasons. Email marketing firm CampaignMonitor explains it pretty well on their blog.

Some clients, like Outlook 2007, won't display the form, but allow you the option to View in browser if you trust the source. Here's how to do this with an SMX message:

Other clients, like Gmail, simply warn you of the danger, and let you go ahead if you think it's safe. Most clients should have some option for allowing you to view messages with forms, and as we find more we'll try and post them.
