Not necessarily. My age range on the last two mailings were 55 to 80 yrs old, and I estimate 90% of my returns fell within the 60 to 70 age range. I have received no returns outside of 58 to 73. I plan to tightened up the range next time and expect a better return.
Wow, I think you will find a good % in that 60/70 but I have received over the years plenty of leads under 60 and over 70.
