Apollo.io vs ClientSuccess
The short version
- Only Apollo.io has a free tier, so it costs nothing to try first.
- 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; ClientSuccess setup and configuration requires significant implementation effort
- They diverge on capability: Apollo.io covers Contact database, ClientSuccess covers Health scores.
