Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Mailchimp

  • The free plan allows 250 contacts and 500 sends a month, with a 250 daily cap
  • Price is driven by contact count, so the list growing raises the bill regardless of how much you send
  • Send allowances are a multiple of contacts, 10x on Essentials and 12x on Standard, so a large list with heavy sending forces a tier change
  • Essentials allows 3 seats and Standard 5; unlimited seats need Premium at $350 a month
  • The headline $13 and $20 prices are for 500 contacts, not a flat rate

Swagger/OpenAPI

  • The OpenAPI Specification itself is licensed under Apache License 2.0 and free to use; SwaggerHub is a separate paid tool built on top of it
