I had a bit of an issue.
We create a ghost blog and activated a newsletter.
The newsletter is received, opened but the dashboad on ghost does not changes.
But the number on the top of his profil does not change as they should :
We did follow a tutorial again to activate some settings on mailgun, but still nothing.
