We use Cloudflare, and Sendgrid for email.
Via Sendgrid setup, we have added a DNS record:
However, this redirects to our main domain:
Example link.construct.net generated by SendGrid
If I disable CloudFlare routing (the orange cloud), the URL creates a security exception because HSTS is enabled for
construct.net and all subdomains.
Am I correct in assuming
link.construct.net should not end up on
construct.net, and how can I resolve this so that the links resolve correctly?
