Active member repeatedly is moved to former members list

Hello,
Every few weeks I find that my name has been removed from our club listserv and moved to the former members list. When I log into our FTH website, I see a message like the one I have copied & pasted below. I have never indicated that I am no longer a member and have never requested to be moved to the list of former members. 
How can this be corrected?
My name appears in the message below, and our club is Old Capitol Toastmasters #164.
Best regards,
Diane DeBok

Your email processor is the issue. It is clicking the not a member link at the bottom of emails from your club 

You will need to contact them to ask how you can stop them from clicking links in your emails.
