Where each one falls short

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

Authorize.net

  • All-in-One plan charges 2.9% + 30¢ per card transaction, higher than Gateway-only rate of 10¢ + batch fee
  • Gateway + eCheck plan limited to U.S.-based businesses only
  • eCheck processing includes $10 minimum monthly fee on Gateway + eCheck plan
  • Chargeback fees apply: $0 for standard processing but $25 for eCheck chargebacks

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
