How a finding earns its place.

Sources

Primary material, attached to the action.

Each rule names its publisher, source URL, publication date when the publisher provides one, and the date Emailrules last verified it. A report snapshots the rule and source used for that check.

Method

How a claim becomes a rule

1. 01

   Find

   Use a regulator, standards body, mailbox provider or sending-platform primary source.

2. 02

   Extract

   Record the exact published fact without turning it into Emailrules advice yet.

3. 03

   Interpret

   State who it applies to, when it starts and what remains uncertain.

4. 04

   Detect

   Define the bounded message, DNS or context evidence that can support a finding.

5. 05

   Review

   A person approves provider and regulator changes before publication.

6. 06

   Recheck

   Watch the source, retain its verification date and publish corrections when the reading changes.

Coverage

A bounded check, not a universal verdict.

Campaign preflight covers message structure, authentication evidence, unsubscribe evidence, sender identity, selected measurement risks and rules applicable to the context supplied. It does not predict inbox placement, certify legal compliance or infer recipient geography.

Freshness

Verification dates stay visible.

The corpus contains 41 public rules. The newest recorded verification is 4 Aug 2026. Source pages are checked for changes, but a machine never publishes a changed interpretation.

Corrections

Site corrections are not market changes.

Provider, platform and regulator changes belong in Changes. Corrections to Emailrules claims are recorded separately so an internal fix cannot be mistaken for an external event.
