I am a complete beginner, so bear with me.
I have successfully created a droplet, and installed my wordpress there.
I am also using cloudflare for my CDN.
Unfortunately I couldn’t get email to work. (Im using third party service for email aka google apps for work)
The email sent from my wordpress is marked as spam.
Upon further conversation with google support, I was told that this is because my PTR/reverse DNS has not been set up.

I have looked at a few tutorials, but they all involved setting up FQDN, to my understanding I need to setup something like for FQDN. Is not considered an FQDN?

Can anyone guide me on how to set PTR/reverse DNS so that my emails are no longer marked as SPAM?

Hey there,

A FQDN would be We automatically configure PTR records based on the name of the Droplet. If the Droplet is named a FQDN the PTR will automatically have a proper reverse DNS. Notably you will want a matching forward DNS record pointing back at the IP address.
