We're all having the same issues. How many customers did Groupon brought to your door. Have you niched your marketing? Who is your demographics? Are you using the cookie cutter marketing brochures? Try running a post card mail campaign to the same clients. Direct mail still out pulls email.I hope you kept their mailing address. You should be mailing minimum 4x a year to your clients. Keep in mind Not everyone opens their email but post cards forces the recipient to read the offer. Make the offer just as enticing but unfortunately, you're gonna have to keep the same price. On the postcards you can also have other optional services for additional cost. Retail should be part of your operation. If you're not up selling your doing yourself a disservice. I read the book "The Ultimate Sales Machine' by Chet Holmes 6 times you both should look into it. Good luck and don't quite.
