Here's a fun idea the next time you receive a referral....send a $1.00 lottery ticket with your thank you note. A handwritten thank you is essential to maintaining strong referral relationships. Why not make it fun at the same time?
Everyone likes to feel appreciated and most everyone likes to win something. Create a memorable experience by including something unique. If your state doesn't have a lottery, make up your own "YOU WON!" ticket for a free icecream or something else. You may even want to see if there is a local business that will allow you to pay when the ticket is redeemed. Often times, gift certificates and coupons are not used and this method can save you quite a bit of money.
It really doesn't matter HOW you do it. Just make sure you say "thank you" to those that take the time to recommend your services. Being creative just makes it a bit more effectice. (Thanks a Million Post)
