What you're looking at. Headline numbers for the analysed Tranco snapshot: how many domains publish each kind of email-related DNS record, and what share of DMARC publishers actually enforce their policy (quarantine/reject). Higher MX vs SPF gap = more domains receive mail than authorise sending; higher SPF vs DMARC gap = SPF adopted but no policy/feedback enforcement yet.

Key findings — 2026-09-03

Each statement is recomputed daily from the full dataset and published under CC BY 4.0 — reuse it, cite "Live Direct Marketing, Email infrastructure of the Tranco top-1M" with a link.

Top mailbox providers

What this block shows. Where each domain hosts incoming mail — derived from its primary MX record (lowest mx_preference). This is the receiving side of email: Google Workspace, Microsoft 365, Zoho, on-prem Exchange, etc. "Generic / unmatched" buckets are common mail.* / mx*.* hostnames we couldn't attribute to a specific provider; "Unknown / Other" is everything else. Note: Cloudflare Email Routing also appears in the ESP table below — that is the same service observed through two different record types (MX here, SPF there), not a double count of domains.

Long-tail / Unknown MX — the rest of the internet

What this block shows. The slice of domains whose mailbox cannot be attributed to a named provider — regional hosters, self-built Postfix/Exim, corporate gateways, niche ESPs. Researchers ask for this specifically because it captures the deliverability reality outside the Google / Microsoft monoculture. The detailed report drills down into Top-1000 most common unmatched hosts, 100 hand-picked curiosities (longest one-off names) and a TLD breakdown.

The same metrics cut by list position. Enforcement is a function of how big the site is: the gradient from the top of the list to the tail is the finding, not the average. "Not in current list" = domains measured in this snapshot that are absent from today's Tranco file (list rotation).

Top ESPs / mass-mailing services

What this block shows. Outbound mass-mailing platforms each domain authorises in its SPF record — the marketing-automation, transactional-email and customer-engagement layer (SendGrid, Mailchimp, Mailgun, Klaviyo, HubSpot, Salesforce Marketing Cloud, etc.). One domain can use several ESPs, so percentages sum to more than 100% of SPF-publishing domains.

SaaS senders (Notion, Slack, Zendesk, Atlassian, Stripe…)

What this block shows. SaaS apps that send mail FROM a customer's domain on the customer's behalf — productivity, support, payments, HR, e-commerce and other business apps appearing as include: targets in the customer's SPF.

DMARC adoption

What this block shows. The policy each DMARC-publishing domain advertises at _dmarc.<domain>: none = monitor only, quarantine = mark as spam on fail, reject = drop on fail, invalid = a syntactically broken record. "Enforced %" treats only quarantine / reject with pct=100 as actually enforcing.

Does the DMARC record actually do anything?

A three-way split instead of the usual enforced/not-enforced binary. Enforcing — p=quarantine or p=reject. Monitoring — p=none with a working rua= address: a legitimate rollout phase, someone is reading the reports. Inert — p=none with no reporting address at all: the record enforces nothing and reports nowhere.

35.67%
DMARC without reporting address
170 875 domains publish DMARC but receive no aggregate reports
25.20%
Inert records (p=none, no rua)
120 689 domains — the record does nothing at all
36.43%
Reports go to an external vendor only
174 478 domains send every report off-domain

Maturity split of 478 978 DMARC-publishing domains: 49.45% enforcing, 25.31% monitoring, 25.20% inert. Under DMARCbis (RFC 9989/9990/9991) the pct= tag no longer exists, so the same snapshot yields 49.45% enforcing against 47.18% under RFC 7489 — both are published, the RFC 7489 figure keeps the 2016 series continuous. DMARCbis adoption is still marginal: 385 domains (0.08%) publish np=, 87 publish psd=. 984 records carry a rua= tag that parses to no usable address at all.

Mailbox provider × sending platform

Which sending platforms sit on top of which inbound stack. Cell = domains whose primary MX belongs to that mailbox provider and whose SPF authorises that ESP; the percentage is of that provider's domains. A domain may use several ESPs, so rows do not sum to 100%.

Reverse DNS: the failure nobody publishes

What this block shows. Every MX hostname in the snapshot was resolved to its addresses, and those addresses resolved back. A missing PTR is one of the very few things visible in DNS that makes large providers reject mail outright — a diagnosis, not a statistic.

51.12% of self-hosted domains publish a PTR that does not match the zone of their own MX host
22 190mail hosts with no reverse record at all, of 367 155 resolvable

Run it yourself and it breaks; hand it to a provider and it does not. The dictionary classifies a domain as self-hosted when its MX lives under its own apex.

Methodology — how the numbers were produced

1. Data source

The dataset is the daily OpenINTEL forward-DNS Tranco snapshot (University of Twente / SURFnet / SIDN Labs). OpenINTEL queries the entire Tranco top-1M domain list daily for MX, TXT, NS, A, AAAA, SOA, CAA, DNSSEC and other records, publishing the results as Apache Parquet. For pre-2022 history we additionally use OpenINTEL's alexa source (the legacy Alexa top-1M list, retired 2023).

Cite: Roland van Rijswijk-Deij et al., "A High-Performance, Scalable Infrastructure for Large-Scale Active DNS Measurements", IEEE JSAC 2016.

1b. Where the rest of the analysis lives

Six deep-dive pages are rebuilt by the same daily run and were previously reachable only through the sitemap: SPF health (final all qualifier, DNS-lookup limit, record length) · Email security posture (MTA-STS, BIMI, TLS-RPT, DKIM selectors) · SaaS via verification tokens · DNS/NS providers · Country × ESP · Infrastructure & TLS.

2. Sample & cadence

Each report covers a single date — OpenINTEL publishes snapshot D on D+1, so the current UTC date is never treated as an expected snapshot. Freshness means matching the latest date actually present in the OpenINTEL catalogue, typically ~700 k domains with MX records and ~620 k with SPF. The pipeline runs daily at 03:00 UTC, after the usual source-publication window; each daily run produces an HTML report, a JSON summary, an updated time-series, and incremental updates to the domain registry (§ 12). No sub-sampling.

3. Mailbox provider classification

For each domain we read its MX RRset and pick the record with the lowest mx_preference as the primary mailbox host. The hostname of that primary MX is matched against an open regex dictionary (dictionaries/mx_providers.py, currently 328 patterns, hash below). Specific patterns (e.g. .mail.protection.outlook.com) are tried first; generic fallbacks (mail.*, mx*.*) only after. Domains whose MX matches no rule are kept as "Unknown / Other" — never dropped — and exported in Unmatched MX targets for dictionary improvement.

4. ESP / SaaS / forwarder / gateway classification (SPF-based)

For each domain's apex SPF record (TXT starting with v=spf1) we extract every include: and redirect= target and resolve them against open classification dictionaries (ESPs, mailbox-as-sender, anti-spam gateways, forwarders, SaaS senders, DMARC vendors, NS providers, verification tokens).

Resolution order: PURE_ESP → MAILBOX_AS_SENDER → GATEWAYS → FORWARDERS → bare-apex substring fallback → SAAS_SENDERS substring iteration. Bare-apex derivation strips leading _spf., _spf-eu., spf., mail. prefixes from dict keys to catch subdomain variants (e.g. _spf.m1.websupport.sk → matches websupport.sk). Malformed includes (no dot, <4 chars) are filtered.

One domain may use several ESPs simultaneously, so ESP shares sum to more than 100% of SPF-publishing domains. Current SPF-include target coverage: 82.54%, recomputed from this snapshot rather than hard-coded.

Limitation: "flattened" SPF (where include chains were replaced with raw IP ranges to fit the 10-lookup limit) is not detectable from DNS alone — those domains appear ESP-less even when an ESP is in fact used.

5. DMARC (deep)

For each domain we query the _dmarc.<domain> TXT record. Records starting with v=DMARC1 are parsed for:

  • p= (apex policy): none / quarantine / reject / invalid
  • sp= (subdomain policy)
  • pct= (rollout percentage)
  • rua= aggregate-report destinations → classified into vendor buckets (Postmark DMARC, Valimail, dmarcian, URIports, EasyDMARC, Red Sift, Proofpoint EFD, Agari/Fortra, …) using dictionaries/dmarc_vendors.py

A domain is counted as enforced if p=quarantine or p=reject with pct=100 (or pct absent — defaults to 100).

6. SPF mechanics & health

For every SPF record we additionally extract:

  • Final qualifier on the all mechanism: -all (hard fail), ~all (soft fail), ?all (neutral), +all (pass-everything — broken / dangerous), or missing
  • DNS lookup count (include:, redirect=, a:, mx:, exists:, ptr:) — each mechanism counts as 1 against the spec limit of 10. Records exceeding the limit return PermErr at recipients
  • Mechanism mix: include-only (modern), raw IP4/IP6 ranges only (legacy/flattened), mixed
  • Record byte length: percentiles to flag fragmentation risk (>450 B)

7. Email security maturity

Adoption of modern mail-security TXT records, parsed from the same OpenINTEL parquet:

  • MTA-STS: TXT at _mta-sts.<domain> with v=STSv1 — domain advertises required-TLS to its MX
  • BIMI: TXT at default._bimi.<domain> with v=BIMI1 — brand publishes a verified logo (requires p=reject)
  • TLS-RPT (SMTP TLS Reporting): TXT at _smtp._tls.<domain> with v=TLSRPTv1 — domain monitors TLS-failure reports
  • DKIM selectors: where the OpenINTEL scan includes *._domainkey.<domain> queries, well-known selectors (google, selector1/2, s1/s2, k1/k2/k3, mailo, mte1, …) are mapped to issuing ESPs

8. DNS provider classification

For each domain's NS RRset, every NS hostname is matched against a suffix dictionary (dictionaries/ns_providers.py) with patterns for Cloudflare, AWS Route 53, Azure DNS, Google Cloud DNS, GoDaddy, Akamai, NS1, UltraDNS, Yandex, DNSPod, Aliyun, OVH, Hetzner, Gandi, registrars, and others. A domain is assigned to its dominant NS provider; ties resolve to whichever pattern was matched first.

9. SaaS-via-verification-tokens

Many SaaS apps a domain is connected to never appear in SPF (because the SaaS doesn't send mail FROM the customer domain). To recover this signal we parse apex TXT records for verification tokens — google-site-verification=…, MS=…, atlassian-domain-verification=…, stripe-verification=…, plus 149 other patterns in dictionaries/verification_tokens.py. This produces a complementary "SaaS density" metric and surfaces apps that the SPF-only view misses.

10. Email infrastructure modernity

Three additional TLS / IPv6 metrics:

  • IPv6-on-MX: MX hostname has at least one AAAA record
  • DANE / TLSA on MX: TLSA record at _25._tcp.<mx_host> (where the parquet includes TLSA queries)
  • CAA: any 0 issue … / 0 issuewild … record at apex; CAs aggregated into a market-share view (Let's Encrypt, DigiCert, Sectigo, …)

11. Cross-tabulations

  • Country × ESP heatmap: top-15 ccTLDs × top-15 ESPs, cell = % of country's SPF-publishing domains using ESP X. Surfaces regional ESP champions (Brevo / FR, Unisender / RU, MailerLite / LT, Akna / BR, Shoptet / CZ).
  • Mailbox × ESP combinations: stacked frequency of common stack pairings — published as Mailbox provider × sending platform.

12. Domain registry & identifiers

Every domain ever observed across snapshots is assigned a stable integer ID in /var/openintel-cache/registry/domains.sqlite3 (currently 1 958 495 domains). Reports reference domains by ID rather than embedding strings; clients resolve names from a single gzipped registry dump (/email-stats/domains.csv.gz, 25.5 MB). This keeps per-report payloads compact, enables fast set-operation diffs across snapshots, and gives every domain a first-seen / last-seen timestamp.

13. Daily change-alerts feed

Each daily run computes a domain-level diff vs the previous scan and emits a change-feed at /email-stats/alerts.html (also as JSON + Atom). Detected events: ESP added/removed in SPF, DMARC policy upgrade/downgrade, primary-mailbox-provider change, SPF strict→soft regression, MTA-STS / BIMI first publication. Severity tag is good / bad / info.

14. Per-entity detail pages

The top-100 ESPs, top-100 SaaS senders and top-80 mailbox providers each have a dedicated detail page at /email-stats/detail/<kind>/<slug>.html showing KPI cards, a Chart.js sparkline (from history.json), TLD distribution and a sample of customer domains.

15. Tier breakdown

Each domain is assigned a tier from its Tranco rank: top-1k / top-10k / top-100k / top-1M, plus unranked for domains measured in the snapshot but absent from the current list file (rotation). Published as Authentication by Tranco tier: SPF, DMARC enforcement and self-hosting per tier.

16. Reproducibility & data hygiene

Dictionary hashes for this run (sha256, first 12 hex):

  • compliance.py — 76d502287abe
  • dmarc_vendors.py — 8c195eb564fc
  • esps.py — 0f7a40a1f7d3
  • mx_providers.py — c29c6e1b1f58
  • ns_providers.py — cc4f43c6651f
  • providers_meta.py — 5dc92db7869f
  • saas_meta.py — fe611e6e8a68
  • saas_senders.py — 1c5ebd9f7c09
  • tld_regions.py — 61e8bd3dcca8
  • verification_tokens.py — 6ba8313e55ab

Every published report includes the exact OpenINTEL date, dictionary file hashes, and counts of unmatched MX hosts and SPF includes — so any reader can verify or reproduce the figures. Raw OpenINTEL parquet is downloaded into a temporary cache and deleted after analysis; only aggregated, non-redistributable counts are kept long-term (per OpenINTEL data agreement). The domain registry stores names but no record-level content.

16b. Methodology changelog

Every change to a metric definition is recorded in the methodology changelog and stamped into each history point as methodology_version — so a step in a series can always be attributed to a formula change rather than to reality.

17. Limitations to be aware of

  • Tranco bias. Top-1M skews toward US/EU and global SaaS; ccTLD-only domains with low traffic may be under-represented. The alexa source used for pre-2022 history has a different composition and a different size: the alexa partition of 2022-04-01 contains 1 637 544 measured apex names against 1 087 498 in tranco on 2026-07-24, so absolute counts are not comparable across the 2022-08-11 boundary — only shares within a snapshot are.
  • SPF flattening hides ESP identity (see § 4).
  • CNAME chains on MX (e.g. mail.example.com → mail.example.protection.outlook.com) are not unrolled — only the first MX target is matched. This biases a small share of domains toward "Unknown" when their MX is a CNAME to a known provider.
  • Vanity MX with white-label provider (Mimecast/Proofpoint customers using their own brand) is not detectable from DNS alone.
  • DKIM enumeration is selector-based — only domains whose well-known selectors are scanned by OpenINTEL appear in the DKIM layer.
  • Long-tail unmatched: this snapshot contains 82 003 unique unclassified SPF targets. The count is published as a measured coverage KPI rather than a fixed estimate; many are regional hosters, tenant-specific endpoints, malformed records, or single-domain infrastructure.
  • Newly-added dictionary entries have no historical sparkline until ≥ 2 daily scans accumulate, since archived raw parquet is purged after parsing per the OpenINTEL data agreement.
