Where each one falls short

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

Apollo.io

  • Everything is metered in credits, and the free Starter plan runs on them too, so prospecting volume is capped rather than the feature set
  • Plans described as unlimited are capped in the fair use policy at 10,000 credits a month for non-paying accounts
  • Connecting a mailbox that is not Gmail or Microsoft requires a paid plan
  • How many records can be selected at once varies by tier
  • Running out of credits means buying more rather than waiting for a reset

Document360

  • No published flat-rate pricing makes it hard to compare costs upfront against competitors.
  • Requires a sales quote process rather than instant self-service signup for paid plans.
  • Advanced AI features are usage-metered and may require additional purchases.
  • Smaller teams may find the enterprise-oriented feature set more complex than needed.
