  Paubox Email API plans. The pricing page renders its price figures client-side from a
  volume selector, so the per-tier dollar amounts are not readable from the served HTML;
  what IS published in machine-readable prose is the tier structure, the monthly email
  quota per tier and the per-email overage rate, on
  https://docs.paubox.com/email-api/limits. Those are recorded here verbatim. Dollar
  prices are recorded as null rather than guessed.
