The short version

  • Each has a real cost: Customer.io essentials plan caps at 5,000 profiles (people and objects) and 1,000,000 monthly emails, with overages billed at $0.12 per 1,000 emails beyond that; Linear no task-level Gantt chart; Timeline view is available for projects only, not individual issues

Where each one falls short

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

Customer.io

  • Essentials plan caps at 5,000 profiles (people and objects) and 1,000,000 monthly emails, with overages billed at $0.12 per 1,000 emails beyond that
  • Standard and Premium tiers show custom pricing only, and Enterprise is negotiated rate, so three of the four published tiers require a sales conversation
  • Monthly plans accept credit card only; annual billing via invoice (ACH/wire) requires the annual commitment

Linear

  • No task-level Gantt chart; Timeline view is available for projects only, not individual issues
  • No native time-tracking or hour-logging feature
  • No native Linux desktop app; official FAQ states it 'may come in the future but it's not on the roadmap for now'
  • Free tier capped at 250 issues and 2 teams
