Normally, I would agree with you. But let me tell you how I found out about this service. It was not through HN. It was by getting two emails from hidnchat. Five minutes apart. Emails that I am quite confident are not legit. (If you think I'm wrong, then I can post my reasons for saying they are spam.) And since the mail headers look much more legit than what a typical spammer sends, my spam filter did not even catch it. I googled hidnchat and found this HN thread.

you can always unsubscribe from this service if you want. Also there are some multiple filters inbuilt into the service restricting you to send multiple mails to the same id.(hourly freq limit, daily freq limit etc.)

Interesting. The frequency limits are a very good idea, and I thank you for them.

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 [e-mail], 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. :)
