Comment to MailJet Setup Tutorial
What is the error? I know that sometimes it can take a while to verify the changes you made based of your domain's TTL settings. So even thought you did the right then, it make take a while to get verified.
Thanks, I guess I'll have to wait 48 hours to check again. The error from Mailjet before I did the last changes was "We detected that your domain has an existing SPF record but it does not allow us yet."
