EDDM - I’ve searched and read and need a little more info

I’ve searched and read a lot about this. This is my first year in biz and was much busier than anticipated in the spring mainly from hanging door hangers. I want to do EDDM starting March 2020. I’ve read that consistently mailing to the same route that has good demographics is imperative.

My question is he avg of a .67 or .5 response rate, is that the response to the first mailing (on average) or is that the response after sending three plus mailings?

My math is 2,500 mailings should create 12 calls (.05% response), I close 70% so I get 9 jobs. Price is 2500 pieces is $1,000 through at cost printing or whatever they are called now. So cost to obtain each job is $110.

So is that what I should expect worst case scenario?

I’m signing up with Jill’s Office and responsibid in Jan 2020 and want to make sure I’m investing marketing $ in the most effective places.

I’ll be putting out signs, continuing door hangers, and mailing/voicemail dropping to current customers.

I really appreciate the help!

I’ve talked to three different google AdWords that have told me the per click cost for my area is way higher than normal, it’s in the $15-$20 range per click, the numbers do not work for me with google ads.
