We use a program called MailPoet and its sending service to send mail to our members. Until recently all we had to do was add a new member and they were auto-magically subscribed. But it seems a recent change in MailPoet enforces “Sign-up confirmation” even though our members never sign-up.
This meant that several new members were in the unconfirmed state and weren’t yet receiving emails. I have now triggered (re)send confirmation email. Those new members will have received an email from the site and have to reply.
A reminder: All logged on members can view emails they may have missed by going to Members -> GYC Docs -> Archived Emails
