The three core checks pass. What is missing is the transport and trust layer around them.

1 · Authentication and transport

SPF

PassValid, soft fail

Anything not on the list is accepted but marked. Google recommends ~all; with DMARC enforced it is as strong as -all.

v=spf1 include:allbirds_com._es.easydmarc.com include:spf.protection.outlook.com ~all

DKIM

Pass7 keys found

Selectors google, selector1, selector2, k1, s1, s2, mandrill publish a public key. 5 of them point at a vendor by CNAME.

google._domainkey, selector1._domainkey, selector2._domainkey, k1._domainkey, s1._domainkey, s2._domainkey, mandrill._domainkey

DMARC

PassPartial (p=quarantine)

Failing mail goes to spam. One step from full enforcement.

v=DMARC1;p=quarantine;pct=100;rua=mailto:postmaster@allbirds.com;ruf=mailto:postmaster@allbirds.com;fo=1

MX

Pass1 host

One host, but it is a provider endpoint that is redundant behind the name.

10 allbirds-com.mail.protection.outlook.com

MTA-STS

ReviewNot published

Sending servers cannot tell that this domain requires TLS, so inbound mail can be downgraded to plain text by anyone on the path.

TLS-RPT

OptionalNot published

Nobody is told when TLS to this domain fails. Cheap to add once MTA-STS is in place.

BIMI

PassPublished

Logo record found and DMARC qualifies. Yahoo shows it from the record; Gmail and Apple Mail also need a VMC or CMC certificate (the a= tag).

v=BIMI1;l=https://vmc.digicert.com/faeed248-398e-4fa8-a86d-c03dc037898a.svg;a=https://vmc.digicert.com/faeed248-398e-4fa8-a86d-c03dc037898a.pem

DNSSEC

OptionalNot signed

Optional. Signing the zone protects every record in this report from tampering.

Only tools that leave a DNS trace appear. A shared DKIM selector is attributed only when its CNAME target names the vendor.

4 · What to fix, in order

  1. P2

    Finish DMARC at p=reject

    Quarantine still delivers spoofed mail, just into spam.

    Publish at_dmarc.allbirds.com
    v=DMARC1; p=reject; rua=mailto:dmarc@allbirds.com; fo=1
  2. P3

    Publish MTA-STS (record and policy file)

    Tells sending servers to require TLS to your MX hosts, which prevents downgrade attacks. The TXT record alone does nothing: the policy file must be served over HTTPS at mta-sts.allbirds.com. Start in testing mode, watch TLS-RPT, then switch to enforce.

    Publish at_mta-sts.allbirds.com and https://mta-sts.allbirds.com/.well-known/mta-sts.txt
    TXT  v=STSv1; id=2026100401

mta-sts.txt:
version: STSv1
mode: testing
mx: allbirds-com.mail.protection.outlook.com
max_age: 86400
  3. P3

    Publish TLS-RPT

    You get a report when TLS delivery to your domain fails; this is what notices a downgrade that MTA-STS is meant to prevent. The address must exist.

    Publish at_smtp._tls.allbirds.com
    v=TLSRPTv1; rua=mailto:tls-rpt@allbirds.com
  4. P3

    Sign the zone with DNSSEC

    Protects every record in this report from being swapped in transit. Two steps: enable signing at your DNS host (one switch at Cloudflare and most others), then add the DS record it gives you at your registrar.

How to verify this yourself. Every line above comes from public DNS. Run dig TXT _dmarc.allbirds.com or dig MX allbirds.com and compare. Method: theemailstack.com/methodology.

Scores weigh SPF 20, DKIM 15, DMARC 30, MX 10, MTA-STS 10, TLS-RPT 5, BIMI 5, DNSSEC 5. Message-level requirements (alignment, unsubscribe headers, complaint rate) are not checkable from DNS and are marked as such, never guessed.

About this report

The Email Stack reads public DNS for well-known domains and publishes the result as a report, the same one anyone can generate for any domain at /report. It is a point-in-time read: records change, and a domain that scores C today may score differently next month. The "Re-run live" button reads DNS again in your browser.

Scores weigh SPF 20, DKIM 15, DMARC 30, MX 10, MTA-STS 10, TLS-RPT 5, BIMI 5 and DNSSEC 5. Tools are named only when a DNS record names the vendor; a shared DKIM selector counts only when its CNAME target does. Message-level requirements such as alignment and one-click unsubscribe cannot be read from DNS and are marked as such, never guessed. Method: how we detect tools.

Own this domain and see something wrong? DNS is the source; fix the record and the next read will show it. Questions to hello@theemailstack.com.
