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

TaxJar

  • Both published plans include only 200 orders per month, so higher volume costs more
  • The Starter plan at $39 per month allows only 3 data import integrations
  • AutoFile state filings are metered: Starter includes 2 credits a year and each extra filing costs $50, Professional includes 4 and each extra costs $55
  • Real time tax calculation API access requires the Professional plan at $99 per month
  • Phone support, a Customer Success Manager and a dedicated onboarding specialist require the Professional plan
  • The developer sandbox requires the Professional plan
  • The 10% saving requires annual billing
