Email delivery issues either you are not receiving certain emails, or emails are not received to your intended recipients, are caused by a variety of reasons.
Please check if the emails are sent to Spam or Junk Folder; or if you are receiving a bounce-back email that should detail the reason why the email is not being delivered.
Emails not being received or sent may also be caused by a server blacklist/deny list or external mail host refusing to receive the mails.
You may also try resending the email in question but if you continue to experience issues, please contact usĀ hereĀ - https://www.ourchurch.com/contact-us/
