I never get daily emails, but regardless, they provide fine-grained control over unsubscribing to these emails. If you receive them daily, you might want to take 5 minutes and opt out.
If an opt-out takes more than ten seconds (find opt-out, click it, close tab, alt+tab back to email) I add it to my spamfilter. And that means I will never read email from that sender again, not even in my spam folder, unless I am expecting e-mail and (temporarily) remove it from my blacklist.
