The short version

  • Each has a real cost: 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; Signal signal must be installed on a phone before the desktop app can be used, so there is no phone-free desktop-only account
  • They diverge on capability: Apollo.io covers Contact database, Signal covers End-to-end encryption.

Where each one falls short

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

Apollo.io

  • 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

Signal

  • Signal must be installed on a phone before the desktop app can be used, so there is no phone-free desktop-only account
