I think of spam like a lot of direct physical mail. There’s two effects going on: 1. People will continue to use an easy tool even if it has become ineffective, because it’s available. It doesn’t take many spammers to send 100,000,000,000 emails. Direct mail isn’t what it used to be, but it’s baked into the systems for every car dealership and so it continues. Spam is probably 1000x less effective than it was in 2002, but most spammers aren’t running A/B tests either. 2. Just like direct mail, it’s easy to think that no one looks at spam because I don’t. In fact, there really are a lot of people who look at every coupon in the Captain D’s flyer. Same thing with spam…even if the open rate is 0.1%, that could still be 1 in 1000 people.
