I’ll keep this simple: I don’t sell your contact information to anyone, ever.
By joining my newsletter, you agree to receive emails from me, and only from me. These emails will be funny, informative, and generally awesome. Some of my emails will be trying to sell you stuff, but the emails will all come from me.
Some emails and articles will contain affiliate links, which means they’re offering to sell you things that are sold by other people, and if you make a purchase, I get a cut of the revenue. They’re still written and sent by me- the person selling the product doesn’t see your contact information or even know who you are.
Nobody but me ever sees your name and email address. You’re also free to lie about your name if you want to- but you need to enter your real email address if you actually want to receive anything from me.
