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

SE Ranking

  • Core plan caps keyword tracking at 2,000 keywords and 10 projects; Growth caps at 5,000 keywords and 30 projects
  • The 20 percent discount requires paying annually upfront rather than monthly
  • AI prompt tracking is capped at 100 prompts daily on Core and 250 on Growth
