# Decisions Mailing List Routing Report

Date: 2026-07-04

Source: `decisions.json`

Purpose: interpret `decisions.json` as the user intent for mailing-list handling and translate it into mailbox structure proposals.

## Summary

`decisions.json` contains 185 sender/list decision entries:

- `h` ("houden"): 95 entries, 2,762 messages.
- `a` ("afmelden"): 89 entries, 2,683 messages.
- `s`: 1 entry, 26 messages.

The current sorter does not read `decisions.json`. It only reads the hardcoded routes in `mail_routes.py`. Therefore these decisions are currently advisory data, not active routing behavior.

## Interpretation

Recommended interpretation:

- `keuze: "h"` means keep the list and route it to a normal functional mailbox.
- `keuze: "a"` means isolate it under `Afmelden`, so it can be reviewed/unsubscribed without polluting normal destination folders.
- `keuze: "s"` is ambiguous. Treat it as "separate/review" until confirmed; for now it should be kept in a functional mailbox or a review mailbox, not under `Afmelden`.

For `Afmelden`, use a separate top-level tree:

- `INBOX.Afmelden.<Category>.<Organization>`

Do not place final folders under `Archief`.

## Combined Groups

The following entries should be combined because they appear to come from the same organization/person even when domains differ:

- Coursera: `coursera.org`, `email.coursera.org`, `m.mail.coursera.org`, `m.learn.coursera.org`.
- MIT Technology Review: `technologyreview.com`, `fulfillment.technologyreview.com`.
- Eva Keiffenheim: `evakeiffenheim.com`, `eva keiffenheim s lifelong learning club`, `eva keiffenheim from the learn letter`, and their `substack.com` transport.
- KPN: `kpn.com`, `campagnes.kpn.com`.
- PostNL: `postnl.nl`, `notificatie.postnl.nl`, `edm.postnl.nl`.
- STRATO: `strato.com`, `news.strato.com`, `marketingradar.strato.com`.
- Unive: `nieuwsbrief.unive.nl` and any future `unive.nl`.
- ICS: `icsmarketing.icscards.nl` and any future `icscards.nl`/`service.icscards.nl`.
- Viking: `delivery.vikingdirect.nl`, `online.vikingdirect.nl`, and any future `vikingdirect.nl`.
- bol: `bol.com`, `feedback.bol.com`.
- Coolblue: `coolblue.nl`, `coolblue.eu`.
- Vodafone: split by intent: keep `zakelijk.vodafone.nl` in normal telecom, but place `vodafone.nl` under `Afmelden` because it is marked `a`.
- Sophos/Cleverbridge: `home.sophos.com`, `cleverbridge.com`.
- Forte Labs/BASB: `fortelabs.co`, `fortelabs.com`.
- CIONET: `mn.co`, `cionet.com`.
- Gusti: `gusti-leer.nl`, `gusti-leder.de`, `gusti-pelle.it`.
- Nord: `nordvpn.com`, `nordpass.com`.
- DHL: split by intent: keep `dhlparcel.nl`, but place `dhlecommerce.nl` under `Afmelden` because it is marked `a`; `proxy.privault.rpip.nl` should be treated as DHL if retained.
- Proton: `proton.me`, `notify.proton.me`, `mail.proton.me`.
- Vonage/Nexmo: `vonage.com`, `insights.vonage.com`, `nexmo.com`.
- Visme: `accounts.visme.com`, `visme.co`.
- ClickUp: `clickup.com`, `team.wrike.com` are not the same organization; keep separate.
- Pleio/IBDS: `pleio.nl`, `mail.pleio.nl`.

## Separate/Review

`circle8.nl` is marked `s` with 26 messages.

Recommended temporary mailbox:

- `INBOX.Werk.Opdrachten.Circle8`

Reason: Circle8 is already present as a work/opportunity route in `mail_routes.py`. The meaning of `s` should be confirmed before moving it under `Afmelden`.

## Conflicts With Current Routes

These decisions conflict with the current hardcoded route table or expose incomplete routing:

- `researchgatemail.net` is a high-volume `a` decision but has no active route, so it currently remains in place.
- Keiffenheim Substack messages are `h` but cannot be routed by domain alone because `substack.com` is shared. Need List-ID, sender address, or display-name matching.
- `fortelabs.co`/`fortelabs.com` are marked `a`, but old mailbox naming suggests they may currently live under `INBOX.Mailinglists.BASB`; they should not become a normal final folder if the decision is to unsubscribe.
- `alfen.com` is in the current active EV route but is marked `a` in `decisions.json`. This should be resolved before applying generated routes.
- `vodafone.nl` is marked `a`, while `zakelijk.vodafone.nl` is marked `h`. The route table currently maps both consumer and business Vodafone into `Diensten.Telecom.Vodafone`; this should be split.
- `dhlecommerce.nl` is marked `a`, while `dhlparcel.nl` is marked `h`. The route table currently maps both to `Bestellingen.DHL`; this should be split.
- `proton.me` and `notify.proton.me` are marked `a`, but `mail.proton.me` is a zero-count `h` placeholder. Keep these separate until the user clarifies.

## Plan To Add This Structure

1. Introduce a structured policy file generated from `decisions.json`.
   - Suggested file: `mailinglist_routes.json`.
   - Fields: `action`, `mailbox`, `domains`, `sender_patterns`, `list_id_patterns`, `source_decision_keys`, `notes`.
   - Do not make `decisions.json` itself the runtime file; it contains unsubscribe URLs and analysis artifacts.

2. Extend `mail_routes.py` to load mailing-list policy.
   - Keep `DOMAIN_ROUTES` for stable functional/business mail.
   - Add a runtime lookup for generated mailing-list rules.
   - Support domain matching, exact sender address matching, display-name matching, and List-ID/header matching.

3. Add `Afmelden` to destination folder creation.
   - `maak_mappen.py` should create all `INBOX.Afmelden.*` folders from the generated policy.
   - Existing `destination_folders()` should include both functional keep folders and unsubscribe review folders.

4. Update routing precedence.
   - Invoice keyword routing should remain first.
   - Exact/list-specific mailing-list rules should run before broad domain rules, especially for shared senders such as `substack.com`.
   - Domain rules should remain the fallback for normal service/vendor mail.

5. Add audit output before moving.
   - Dry-run should report counts per proposed destination, including `Afmelden`.
   - It should also report unmatched `decisions.json` entries and current-route conflicts.

6. Resolve conflicts before actual execution.
   - Confirm `circle8.nl` meaning for `s`.
   - Confirm `alfen.com`, `vodafone.nl`, `dhlecommerce.nl`, and Proton split behavior.
   - Confirm whether zero-count aliases should be kept as future aliases.

7. Test only on `backup@australius.nl`.
   - Create the new folder structure in backup.
   - Run dry-run sorter on backup.
   - Review planned moves.
   - Run actual sorter only after explicit confirmation.
