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

Leadpages

  • HTML Pub tiers (Starter to Business, $10–$49/month) limited to 5–50 pages without optimisation features
  • Full optimisation features (A/B testing, Smart Traffic, heatmaps) only available in Grow tier ($99/month) and above
  • AI credits vary by plan, with Starter limited to 4,000 credits (insufficient for heavy AI usage)
  • All plans include unlimited traffic, but AI credit limitations may restrict heavy use of page generation features
  • 20% savings only apply with annual billing; monthly billing charges full price
