Frequently asked questions

What should I check first in Mail Tools?

Start with MX Lookup for routing visibility, then validate SPF, DKIM, and DMARC in that order for clearer root-cause analysis.

Can SPF pass while email still goes to spam?

Yes. SPF is one layer only. DKIM alignment, DMARC policy, reputation, and content quality also affect inbox placement.

How often should we re-check email DNS records?

Run checks after DNS edits, provider migration, and periodically as part of release and security maintenance workflows.

Why is DMARC important if SPF and DKIM are already set?

DMARC defines policy enforcement and reporting, helping domain owners control spoofing outcomes at receiver side.
