Hi there! We send preview emails to our email domain and so far this hasn’t been an issue, until this month. If we send it to another domain (including gmail), we receive the email, but not when it’s sent to our own domain.
(When we send out the campaign, we do receive that campaign email in our email domain).
As far as I can see DMARC etc has been set up correctly.. and hasn’t changed either. We set that up months ago and never had an issue until this month.
Is there anything we can check to see why the preview email is not coming in?
