Some of them only promote offers. Some of them promote offers every day. Others do it monthly, or every other week.
But then there are some people that every couple of days send out a random email. It mentions a new blog post, maybe something new they released, but the majority of the email just talks about their week. Generally "their week" doesn't revolve around the cheeseburger and fries they had for lunch, but rather maybe something they learned (which generally has some vague relation to online business) or some thoughts (again, usually online business or IM related).
Do you like reading about people's lives? Is it an email you'd open? For example, I'm part of Tiffany Dow's email list (no referral link - haha), and a lot of the time she talks about random stuff - like her date nights. BUT! I read them. I don't know why, I just do. And I enjoy them.
Argue. Banter. Brawl. I'm all ears!
