I have a plan to use the email routing feature but am unable to receive the verification email. I can receive every email from Cloudflare except for this part. I also saw another close topic, but I didn’t get any answer on it.
However, it can be irrelevant, but I have already set the following DNS records for my domain.
@ MX 38 route3.mx.cloudflare.net. @ MX 45 route2.mx.cloudflare.net. @ MX 25 route1.mx.cloudflare.net. @ TXT v=spf1 include:_spf.mx.cloudflare.net ~all
