Emails not sending from agenda to members

On Sunday 11/27 and Monday 11/28 I sent an email to the members of my club, Suwanee Power Hour and Sugar Hill Toastmasters.  When nothing showed up today, I resent both emails from within my agenda.  I thought it was because I sent them initially from my phone but the 2nd time I sent them from my PC.  Neither of the emails went through to my club members, as I did not receive either of them.  This has always worked in the past and, in fact, someone else from my SPH club sent one and it did go through today.  It was from Sean Motise.

We will need your club numbers so that we can investigate further.

Club numbers 4343169 and 6639097.

I've had a look at the server email logs and I can't see anything that indicates a problem. (However, I'll admit that making sense of email logs is not my strong suit!)

Are you still having a problem? If so, it might be worth checking with your email provider in case the issue lies there.

I can see the agenda gloing to your email address on Nov 28
Make sure you have added agenda@toastmastersclubs.org and server@toastmastersclubs.org to your contacts

I don't believe it is a problem with my email service because I have been sending these out to various clubs for years and never had a problem.  Yes, I am supposed to be copied on these emails.  However, not only am I not getting them, neither is anyone else.  This just started in the last week or so.  This is an important part of reminding adults to do what they are supposed to be doing anyway, signing up for roles.
