The short version

  • Only Moz has a free tier, so it costs nothing to try first.
  • 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; Moz smaller keyword database with only 500M+ keywords compared to 25 billion for Semrush

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

Moz

  • Smaller keyword database with only 500M+ keywords compared to 25 billion for Semrush
  • Unreliable competitive analysis for B2B companies with niche competitor sets
  • Weekly rank tracking on lower plans creates bottlenecks versus daily updates on competitors
