I've had an online site for years, currently with around 3000 users. I want to start a newsletter but am unsure of the laws for this (I've read CAN-SPAM guidelines but this subject isn't really mentioned). The users, when registering for the site, didn't get a "Do you want our newsletters" option, whether express or implied.
I do not want to be labeled a spammer: indeed, the first newsletter will make it clear that users will have to opt IN to receive future newsletters.
So, can I send an initial newsletter to all my users, even though they never agreed or disagreed to such?
