Hello I tried for the last few days to send a group email but keep getting the following error.
We have a custom domain deerparktoastmasters.org, (club #6859), thus the members group email is members@deerparktoastmasters.org
This has been working well until the last few days and now receiving this message. I use my registered member email to send the email and it worked well until now.
Delivery has failed to these recipients or groups:This email address is being protected from spambots. You need JavaScript enabled to view it.
Your message wasn't delivered. Please try resending the message.
