You might be a spammer if

• you think in terms of “prospects” not “clients” or “customers”
• you think only of the revenue that the people on your list represent
• you think that “best practices” are rules that apply to other people, but not you
• you think that businesses who use your product or service are in business for the sake of doing business instead of helping clients solve problems
• you think that adding random text to your email will solve all of your delivery problems
• you think that “deliverability” is about doing the minimum to get by “the ISPs”.
