The initial mail tests I did this morning arrived in my mailbox about 3 hours later. Just did another test and it sends the mail successfully. Must have been something with the host.
I do still get the message “Unsaved changes may not be saved” when I add the conditional fields. But it would appear that the changes are being saved. Any specific reason this might be happening?
Sorry, I don’t want to waste your time but appreciate the support and feedback.
