There is not even a captcha to reduce abuse by spammers; just punch in an e-mail address, and click "Send", wee!
I sent myself an e-mail, viewed it raw, and promptly updated my mail server configuration to drop SMTP connections from that same sender/host.
And say someone uses this for mailing an anonymous threat (bomb, death, ...); why would you want to expose yourself to any such trouble.
By the time you properly deal with the spam and legal stuff, you're on your way to cloning Hotmail. (Gmail, if you do a better job of it.)
What, those are not anonymous, you say? Yes they are, to a degree; anyone can make "fake" throwaway addresses with the free online mail services. The inconvenience of having to register (as opposed to just filling in a form and clicking Send) reduces abuse. These services also don't promise anonymity to anyone; do something illegal an they will reveal to the authorities your IP address and all access logs pertaining to it.
(Are these hidnchat guys willing to provide anonymity assurances greater than that?)
Unsubscribing on the other hand, seems strange to me. What exactly does it mean to unsubscribe? Normally, "unsubscribe" means something like "I once gave you my email address because I wanted to receive your weekly newsletter, but I don't want it anymore, so stop sending it to me and remove my address from your records".
This seems different: "Somebody else gave you my email address so that you could email me on their behalf. I did not like their email, so please add my email address to your permanent records, so that if anybody ever tells you to email me again, you can block that request".
Imagine I got some spam from spammers@gmail.com, and at the bottom of the message was a link: "click here to unsubscribe from Gmail". If I click on that link, nobody with a Gmail account can reach me ever again. I hope we both agree that Gmail will never do this. Instead, they try to make sure that spammers can not send emails using Gmail.
Your service is pretty cool. I doubt I personally will ever it, but I like the idea a lot. Just add some spam control.
Oh, and one more thing: I sent myself a couple of test emails to get a sense of how your service works from both the sender and receiver perspective, and I have one piece of advice. The animation in the background should not loop forever. Ten or twenty times is more than enough, after that it gets distracting and annoying like a broken record. I could barely focus on my email, even though it was just basically "test <a href=/>test</a>". I was pleased to find out that it gets sent as plain text. Keep it that way. :)
Because it was.
A problem you may run into, if your system takes off and attracts many users, is abuses which result in you being black-listed by anti-spam databases like SORBS, SpamCop and Barracuda. I suspect it will be hard to get de-listed, based on the service that you operate.
Since black-listing is by raw IP address, you might make your hosting provider upset. Suppose linode.com dynamically reshuffles a pool of IP addresses among users. You could get some IP addresses black-listed, and then those IP addresses could be cycled to another user under members.linode.com, who then has a hard time sending mail because of you.
Just a thought.
