What matters to us is the email address that shows up for your club Find a Club entry which is here:
www.toastmasters.org/Find-a-Club/03912619-tesol
If you hover your mouse over the blue Email the Club button and look at the email address that shows up in the bottom left corner of the screen, you will see that the email address that shows up is the one that you are saying is the old email address.
So... Despite your belief that all the Club Central sources of email addresses are correct, I would just point you to that page for your club.
*That* is the email address that must be correct, because that is the email address that we are sending the confirmation emails to. We are doing the same query for that email address that the Find a Club page is doing.
So, somewhere in Club Central, you apparently still have an incorrect email address.
My hunch is that your personal email address is correct. However, the email address in question is a
club contact email address, and, in the past, that was set on the same page as the meeting location information. (I have not seen what the updated page looks like.)
My recommendation is that you should look for a meeting information page or similar for your club in Club Central and look for a club contact email address there. Basically, look in places you have not looked before.
As I am no longer a club officer, I cannot log into Club Central to find the correct page. I am hoping that one of our FTH Ambassadors who is a club officer can log into Club Central and grab a updated screen shot of the new page and navigation directions to it for our user docs. This is something that comes up periodically, so we need to make sure we have it in our docs.
