I have an gmail adress as my "from" adress and read in a pop up that free emailadresses are not so good, so I set up an email adress at my own domain but I´m having trouble changing it in the settings area here at convertkit. I can enter it, but I never get the confirmation email and I dont get why. I have tested the email, I can send emails to it from other emails and receive without problem but somehow the confirmaition email disappears. help please
