CNAME records for Systeme.io are not propagating correctly.
What is the issue you’re encountering
Some DNS checkers show CNAMEs as published, others don’t. Systeme.io still says my domain is not authenticated. Emails are not being authenticated or fail to send.
What steps have you taken to resolve the issue?
What I’ve tried:
Checked DNS propagation (MxToolbox, DNSChecker).
Set CNAMEs to DNS only in Cloudflare.
Verified CNAME Flattening setting.
Waited 48+ hours, no change.
Contacted Systeme.io—they don’t see the records.
What feature, service or problem is this related to?
DNS not responding/updating
What are the steps to reproduce the issue?
Check DNS propagation tools → inconsistent results.
Check Systeme.io → domain not authenticated.
Try sending emails → fail or not authenticated.
