Where each one falls short

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

Attio

  • The free plan stops at 3 seats and 50,000 records
  • Outbound email is capped at 200 messages a month on the free plan and 1,000 on Plus
  • Call Intelligence, sequences, advanced reporting and permission controls all require the Pro tier
  • Custom objects are capped at 3 on free, 5 on Plus and 12 on Pro, with unlimited objects reserved for Enterprise
  • File storage is capped at 50 GB on the free and Plus tiers

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
