I recently switched host to WPEngine and during the process I followed their preferred option to point my nameservers to Cloudflare. Everything has seemed to be operating okay for the last week, but today I tried to switch the email sending method.
I had been using Mandrill for transactional emails prior to switching host but since I switched host there have been errors and so WPEngine suggested SendGrid would work better. I signed up to SendGrid today. As part of the Install DNS Records process there were 5 CNAME records to install.
The first two CNAME records on the list have installed on Cloudflare’s DNS management okay but the last 3 on the list give me an error in a red bar at the bottom of the screen, showing DNS Validation Error (Code: 1004). On finding the meaning of this error it looks as though there could be an abuse or terms of service violation but I don’t see what I’m doing wrong.
Does anyone have any guidance or suggestions?
