Is it okay to email that we send spam?
Even with two firewalls, two antivirus programs, I still AWC spam. So I started replying to them, e-commerce advertising my business and then put your address in a special folder called "mail garbage. "Since I first wrote and told me I'm braking any law or what I'm doing is spam? Interesting enough that two people have asked me to remove your mail from my list. Is not it funny? Now included in my e-mail campaigns and all have sold a product to one of them. So this type of marketing Is right?
I think it's not illegal as long as you add a link option in your email (even in very small letters) so that the person may ignore your e-mail list, and must do so if asked. Similarly, most advertisers have to link in your email. So if you want to get rid of your emails, look for that option in your message and click on it.
