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; Sitebulb desktop plans are limited to a single user, so teams need Sitebulb Cloud or paid add-on seats to collaborate.

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

Sitebulb

  • Desktop plans are limited to a single user, so teams need Sitebulb Cloud or paid add-on seats to collaborate.
  • Large sites near or above the 500,000 URL Pro limit require reconfiguration or the Cloud tier to avoid hitting crawl caps.
  • Desktop crawling relies on local machine resources, so audit speed and scale depend on the user's hardware rather than cloud infrastructure.
