Basic, cheap direct mail material that I use with atleast a 10% response

Just thought I'd share what has been working for me and is my best way to get inbound leads. I get at the bare minimum 1 call/email out of every 10 I send, which isn't bad at all. Just to note, the banquet hall letter had a smaller amount, but I'm pretty sure it's because of the longer copy than the rest.

I use a list that I make myself. These letters were offering SEO so my list was mostly businesses on the bottom of page 1 and page 2-5. These are people who had spent money on websites and some type of SEO so I knew I didn't have to sell them on anything, just prove that I can do what I say.

It was just one page in a regular envelope, hand written address with not return address. In the beginning I put my business card inside but I felt that was a waste so towards the end I left it out, but I didn't see it making a difference in my numbers.

The whole concept of how I wrote these were just explain what I offer simply..more leads which is more money. Some of them I had screenshots of their competitors which is a really good tactic to use because no business owner wants to see that.

But I'm not sure if I missed anything, let me know if you guys have questions and if the pros can chime in and give me their 2 cents, I'd appreciate that as well. I'm happy with 10% response but I'm always down to learn better ways.
