 ## [Unreleased]
 
+### Added
+- **Admin interface**: Superusers now have access to a dedicated Admin section in the sidebar with three pages:
+  - **Admin Overview** (`/admin`): System-wide stats (total users, mail accounts, processing runs).
+  - **Manage Users** (`/admin/users`): Table of all registered users with their subscription tier, status, mail account count, and last login. Admins can edit any user's name, email, plan, active status, and promote/demote admin (superuser) privileges. Users can be deleted (with confirmation).
+  - **Manage Plans** (`/admin/plans`): Full CRUD for subscription plans—create, edit, and delete plans with fields for tier, name, pricing, max mailboxes, max emails/day, check interval, and support level.
+- **Auto-promotion of admin email**: When the user whose email matches the `ADMIN_EMAIL` environment variable logs in or registers (via email/password or Google OAuth), they are automatically promoted to superuser. Default value is `christianlouis@gmail.com` (configurable via the `ADMIN_EMAIL` env var).
+- **`is_superuser` field in API responses**: `GET /users/me` and all admin user endpoints now include `is_superuser` so the frontend can conditionally show admin UI.
+- **New admin API endpoints** (all require superuser role):
+  - `GET /admin/users` – List all users with mail account counts.
+  - `GET /admin/users/{id}` – Get a single user's details.
+  - `PUT /admin/users/{id}` – Update user details, plan, active status, and superuser flag.
+  - `DELETE /admin/users/{id}` – Delete a user.
+  - `GET /admin/plans` – List all subscription plans (including zero-price / inactive).
+  - `POST /admin/plans` – Create a new subscription plan.
+  - `PUT /admin/plans/{id}` – Update a subscription plan.
+  - `DELETE /admin/plans/{id}` – Delete a subscription plan.
+- **Admin badge in top bar**: Admin users see a purple shield icon and an "Admin" badge next to their email in the top navigation bar.
+- **`DEFAULT_USER_TIER` env var**: Controls the subscription tier assigned to every new user on registration. Defaults to `free`. Set to `enterprise` (or any other tier) for B2B / Google Workspace installations where all employees should start on a zero-rate plan.
+- **`ALLOWED_DOMAINS` env var**: Comma-separated list of permitted email domains (e.g. `company.com,subsidiary.com`). When set, only addresses from those domains may register or log in. Superusers always bypass this check. Empty (default) = no restriction (normal B2C mode).
+- **Dynamic pricing section on landing page**: The home page now fetches `GET /subscriptions/plans` and renders a pricing section only when paid plans exist. In enterprise / all-zero-rate deployments the pricing section is silently hidden — the page just shows features and a "Get started free" CTA.
+- **B2C copy and branding**: App renamed to **InboxRescue** throughout (was "POP3 Forwarder SaaS"). Landing page hero, feature cards, how-it-works, and footer rewritten in a personal, consumer-friendly tone. Pricing updated to €0.99 / €1.99 / €2.99 per month for Good / Better / Best plans.
+
+### Fixed
+- Test email sender name corrected from "Christian Loris" to "Christian Krakau-Louis".
+- **Mailbox limit always hit at 1**: The `subscription_plans` table was never seeded, so the limit check fell back to the env-var default of `TIER_FREE_MAX_ACCOUNTS=1` for every user regardless of their tier. Fixed by:
+  1. Seeding four default `SubscriptionPlan` rows at startup — **Free**, **Good** (€0.99), **Better** (€1.99), **Best** (€2.99).
+  2. Rewriting the limit check to look up the user's active plan from the DB first, falling back to env-var config only when no plan row exists.
+  3. Bypassing the limit entirely for superusers (admins can always add mailboxes).
+  4. Adding plan limit fields (`max_mail_accounts`, `max_emails_per_day`, `check_interval_minutes`) to `GET /subscriptions/current`.
+- **Zero-price plans hidden from public marketing**: `GET /subscriptions/plans` now only returns plans with `price_monthly > 0`. Zero-rate plans (Free tier, custom enterprise plans) are still managed by admins but never shown in the public pricing UI.
+
 ### Fixed
 - Fixed `TypeError: can't subtract offset-naive and offset-aware datetimes` in `process_mail_account` task when computing `duration_seconds`. After a database refresh, `started_at` may be returned as a naive datetime; it is now normalized to UTC before subtraction.
