New member not receiving opt-in emails

I have the same problem with a new member of Centennial Toastmasters Club 4393266. The member is Ron MacTavish. He has checked his inbox as well as his junk mail/spam

1) Please do not jump on another's thread. Your problem is not their problem.

2) I resent the welcome email and I can see yahoo accepting the email, have him check his spam box.

Hi Brian.
Sorry for popping onto this thread. I hope it is ok to continue now that I am here. If not let me know and I will start over. Ron MacTavish did not receive your email and did check his spam. He has also tried a different email address (not yahoo) with the same result. Do you have other suggestions?

He will have to ask Yahoo what they did with his email.
The only thing we can suggest is to add server@toastmastersclubs.org and agenda@toastmastersclubs.org to his contacts/safelist.
