What it checks
- MX records and who handles your mail
- SPF: present, single record, no +all, under 10 lookups, includes your provider
- DKIM keys at the common selectors (Google, Microsoft 365, Zoho and more)
- DMARC: present, enforcing (quarantine or reject) and sending reports
Questions
Why does this matter?
Gmail, Yahoo and Microsoft now expect SPF, DKIM and DMARC from domains that send mail. Without them your invoices and quotes land in spam, and anyone can send mail that claims to be you.
What does the check do?
It reads your domain's public DNS records — the same lookups any mail server does. Nothing is sent to your mailbox and nothing is changed.
Can you set it up for us?
Yes. Most domains are fixed in one short session. Fixed quote within 24 hours.
