Official-source first
Vendor claims are drawn from official pricing, help, migration, or program pages. Each source is stored with a checked date of 2026-08-24. A source link is provided so you can recheck a plan before acting.
Conflicts stay visible
Kit currently has conflicting official free-plan subscriber figures: the pricing page shows 1,000 while Help describes 10,000. The data is marked needs_manual_review and the public copy does not choose one number as settled. beehiiv partner attribution documents are also held for manual reconciliation.
Calculator boundaries
The calculator uses a transparent rule-based fit heuristic and shows only a documented free-start boundary, a live-pricing check, or a manual-review state. It does not invent a paid-price estimate, scrape pricing, produce a quote, or rank by affiliate payout. Inputs are processed in the browser and are not sent to an API.
Refresh rule
When a price, plan boundary, migration step, or affiliate term changes, the source record should be rechecked before the claim is refreshed. Until an approved tracking URL exists, outbound vendor links remain canonical official links.
