Why MX records matter
MX records answer a narrow but important question: which hosts should accept mail for canva.com, and in what order? When inbound email starts bouncing, queueing, or disappearing, this lookup is often the fastest way to confirm whether the mail-routing layer still points at the expected provider.
That matters because many email incidents are not application outages at all. They are priority mistakes, stale migrations, or missing failover hosts that only show up when the next delivery path is tested in production.
