You don't say at all how this works. Do you scrape the email addresses? What does the email look like? Does it have any sort of opt-out mechanism?
How do emails sent by this conform to Canada's anti-spam legislation, or any other country's anti-spam legislation?
Currently the email is plain-text, but in the future paying customers can customize the email sent
You can opt-out simply by filtering out emails sent from your past contacts, who you do not wish to receive emails from.
I think you really need to think this through again, because there are fundamental problems that you're not getting. Emails sent this way will be considered as spam, and you'll piss off people receiving the emails, and they'll be pissed off at the person who clicked the button, and then that person will get pissed off at you, which I don't think you want.
While your customers are the ones breaking the law you might find your network access increasingly restricted.
I wish there was a better version of NANAE still around.

But if it is a joke site it's attempting to parody bad marketers and they are viciously stupid and thus your parody is indistinguishable from stuff they actually do.
Project Gutenberg started when Michael Hart tried to email copies of the American Declaration of Independence to everyone on his local network; they were not amused and so he set up a website instead.
The first commercial email spam was probably the DEC spam to all Arpanet. http://www.templetons.com/brad/spamreact.html
If you do not have a confirmed, opt-in, agreement with people you're sending bulk email to you need to be very careful or you risk losing internet connectivity. You're not warning your customers about that.
You're also violating parts of Google's tos. Lucky for you Google refuse to take any form of contact from the outside world so your service will survive until someone there notices it.
In the U.S., unless you have a business relationship with the recipients, it's both illegal and immoral. It violates the U.S. federal Can-Spam Act.

I want to see the smile on your face when you're arrested for providing an easy way to violate the law en masse.
