Find the rules that reach your email data.

Choose a country, search the regulation, and get the actual answer: who it applies to, what it requires, how location changes the email path, and what your team still owns.

Countries

A country is published only when the regional plane, applicable rules, primary sources, and known exceptions can be shown together.

The model is global. The directory is deliberately smaller than the roadmap so nobody mistakes a planned region for a live one.

How to use the answers

This directory narrows the engineering and vendor-review problem. It does not decide legal applicability for an unknown organisation.

  1. 01

    Start with the regulated entity.

    The same message can be ordinary for one company and governed by health, financial, government, or critical-infrastructure rules for another.

  2. 02

    Classify the exact data and system.

    Recipient addresses, reset links, health context, attachments, logs, and delivery events do not automatically inherit the same handling rule.

  3. 03

    Trace the complete email path.

    A location claim must survive queues, logs, webhooks, support access, subprocessors, retention, deletion, and final delivery to the mailbox provider.

The source is part of the answer.

Every rule page links to the legislation, regulator standard, or official guidance used to write it. Each source carries its last checked date. Live procurement and legal decisions should always return to that primary material.

Primary material first

Regulators, legislation registers, government security guidance, and Boundry’s published architecture.

Scope before slogans

Every answer separates who is covered, what is required, what location changes, and what it does not solve.

Dates stay visible

Laws and product boundaries move. The page shows when each source was checked so stale answers are easier to spot.

Boundry Rules is an engineering and vendor-evaluation resource, not legal advice.
