Back in the early days of email we were more worried about choosing the perfect username than we were about marketing. In fact I distinctly remember being more stressed over forwarding a chain email to five other people, because it’d somehow improve the chances of my high school crush declaring their passionate love for me, than I was about whatever newsletter found its way into my inbox.
Create your mailing. The success of direct mail requires designing a compelling mailer. To do that, you need to understand copywriting. It's not enough to tell people about your business. Instead you need to entice them by speaking to their needs and offering to be the solution to their problems. You are allowed to put text on an envelope, so don't forget to put a message that entices people to open your letter.
Once your list is targeted, you need to spend an equally large portion of time coming up with a great deal – even if it means you might lose a bit of money on it. The underlying goal of any marketing campaign is to gain new customers, and it’s worth it to significantly reduce your profit margins to gain said customers. Once you have a surgically-honed list and an amazing offer, then you can spend some time on the design, copy, delivery methods, postage rates, date of delivery, size of the mailer…there are a lot of other options to consider, but following the 40/40/20 rule you can see how important audience and offer truly are.
