Erroneous email sent to members after emailing agenda

Hi,
Analog Orators toastmasters' members intermittently get the below email after the next meeting agenda gets sent out for  Analog Orators (toastmastersclubs.org)  Is there anything we can do to prevent this email from going out? Subject Line: Please confirm you are *not* a Member of Club 6892975 nowA "Not a Member" link was clicked in an email to request that [member name] be moved to Former Member status in the website for club 6892975, Analog Orators. If you clicked that link, then please also click the following link to confirm that your status should really be changed to Former Member status in the website: urldefense.com/v3/__https://6892975.toas...uzpYbDADTMymCSYwAyW$ If you did not click that link, then please just ignore or delete this email. (You may also want to discuss disabling the "Not a Member" links with your club website admin or discourage your members from forwarding emails.) Note that this only affects your status in the club 6892975 website.  It does *not* affect your status with Toastmasters International--that is separate and different. >>> We apologize for requiring this extra step--it has become necessary due to problems caused by people clicking the "Not a Member" link in emails forwarded to them (not originally sent to them). Thank you for all that you have accomplished in Toastmasters and all that you have contributed to your club! The FreeToastHost Administration Team

Disable the 'Not a Member?' link in your club's email settings. This will remove the link that some email processors trigger and cause that message.

Great, thank you we will try that.
