This is not the case. You are still an active member of the SCGA. 

At the time we generated our mailing list, your membership at <<Golf Course Name>> had expired, but today our records indicate that you’re still an active member of at least one SCGA member club and your GHIN number is <<GHIN#>>.

We apologize for any confusion this may have caused. If you have any further questions about your membership, please don’t hesitate to reach out.
