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

Swell Commerce

  • Each plan carries an annual revenue ceiling, and exceeding it is charged as a percentage of the excess: 2 percent on Starter down to 0.4 percent on Unlimited
  • Starter at $29 a month allows 2 admin users and includes only 100,000 API requests and 1GB of storage per month
  • Additional API requests cost $5 per 100,000 and extra storage $5 per GB
  • Role based permissions and developer support are restricted to the Unlimited plan at $2,250 a month
  • Advanced reports and priced currencies require the Standard plan or higher
  • Published prices are the billed yearly rates, so monthly billing costs more
