Free keys for open work
A declared key admits the paid tiers without changing the terms: the AGPL still applies, and the notice says so. Each route is one command. The research and teaching page covers the academic routes and how to cite Mailwoman.
- Open-source project · to the next quarter date
mailwoman license declare --intent open-source --name "<project>" --project <source URL>- Academic · one year
mailwoman license declare --intent academic --organization "<university>" …- Student · one year
mailwoman license declare --intent student --organization "<school>" …- Non-profit · to the next quarter date
mailwoman license declare --intent non-profit --organization "<name>" …- Evaluation · thirty days, once
mailwoman license evaluate --name "<team>" --email <address>
What we commit to
- Your rate is fixed at signup.
- A later price rise applies to new subscriptions. Yours stays where it started while it is active.
- Published releases stay published.
- Every AGPL release already shipped is yours permanently. We could not withdraw that grant.
- We do not count your lookups.
- There is no usage to true up at renewal. Eliminate the per-request bill works the arithmetic.
- A key never changes what runs.
- An artifact already on disk keeps working after its key expires.
What we do not commit to
- A data refresh cadence.
- The gazetteer is rebuilt when coverage changes or an ingest bug is fixed. Each artifact is sealed and dated, so you can tell which vintage you run.
- A license for the data.
- Ours covers the code. The reference data comes from open sources with their own terms. Read Security and compliance before you ship.
