The short version

  • Only Attio has a free tier, so it costs nothing to try first.
  • Each has a real cost: Attio the free plan stops at 3 seats and 50,000 records; Campaign Monitor the Lite tier caps monthly sends at 2,500 regardless of contact list size, so a list of any meaningful size cannot be emailed even once a month without exceeding it.
  • They diverge on capability: Attio covers Custom data model, Campaign Monitor covers Drag-and-drop email builder.
  • Prices and features above were last checked on 1 September 2026.

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

Campaign Monitor

  • The Lite tier caps monthly sends at 2,500 regardless of contact list size, so a list of any meaningful size cannot be emailed even once a month without exceeding it.
  • Unlimited sending only starts at the Essentials tier, so the cheap headline Lite price is not comparable to competitors that offer unlimited sends at their entry tier.
  • Its e-commerce-specific automation (abandoned cart flows, predictive segments) is less developed than Klaviyo's, making it a weaker fit for retail-heavy senders.
  • As part of the Marigold group alongside Sailthru and other acquired brands, product roadmap priority is shared across a portfolio rather than dedicated solely to Campaign Monitor.
  • Pricing multiplies on two axes, contact tier and plan level, so estimating total cost requires checking both dimensions rather than a single number.
