It is with regret that I inform you that I am resigning as a member of the (Name) Club. I have been a dues-paying member for the last (number) years, and in that time I feel that I have significantly contributed to our community and established many strong and lasting relationships. However, for personal reasons I find it necessary to give up my membership, effective date.)
I would greatly appreciate your acknowledgement and release of all further dues, fees and obligations. Thank you.
