  Nutshell is a CRM and email marketing platform for small to mid-sized B2B
  sales teams, providing pipeline management, contact and company records,
  reporting, automation, and built-in email campaigns. The product unifies

  for contacts, leads, accounts, activities, and pipelines, plus a legacy
  JSON-RPC API, both authenticated with an API key.
