Just like with any other form of advertising, you will need to hit people with your message more than once in order to maximize effectiveness. Your first send might pique their interest, but people are receiving mail at the same time they are getting home, and are facing many distractions. By consistently sending marketing messages, you increase the chance that they will convert.
You don’t even have to think you’re a spammer to feel bad. Many of us feel bad just for sending too many emails. Often solopreneurs are downright terrified of sending an email update to their subscribers. They say they don’t know what to say, but I think it’s that they’re afraid, somehow, that they’re bothering their subscribers. They aren’t sure they deserve to be in their inboxes, even if those same people signed up for their emails (through a double opt-in process, of course).
Unlike online content, direct mail cannot be ignored. A catalog sits in someone’s inbox, earning attention whether the person buys a product because of the content or throws the mailer in the trash. “It’s worth it to put the time and energy in because you get to sell one-on-one to the prospect with very few distractions,” Simpson says. “That’s why I love direct mail.”
