Do you find email configs(SPF/DKIM/DMARC) hard for your domain?

Hi everyone,
Hope everyone is making great progress in their IH journey?

My first post here on IH. So please go easy if I break any rule.🙂

I am researching on something. I see it’s often very hard for most folks to find/figure out the correct configuration for sending their email newsletters.

Mistakes in this usually marks your emails as spam by your receivers servers.

Wondering how is it working for you? Is it easy for you to figure out when you (mis)-configure your domain records according to your providers?

Thanks in advance!🙏
