Thank you for the response. I sent out a test mailer to 500 people with a BRC and found out after that the BRC was too small, so I got 0 response. Live and learn. I had an option to call me as well, but I think I'm going to take that off as I got no calls either.
That was mailed out only 3 months in advance. I have the card corrected and am going to test 6 months out now.
My mail permit is expired, but I'm going to go renew that so I can test with pre paid postage response as well.
I added my phone number for a few months, not only did I not get any calls, I got a smaller return rate.
6 months and as generic as possible should easily get you a better return. I’ll probably take out 5 months soon and only mail 6,7 and 8. I like to keep my pipeline full. Just make sure you have a good follow up system.
