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; Calendly the free plan allows one event type and one calendar connection, so it cannot handle different meeting formats
  • They diverge on capability: Apollo.io covers Contact database, Calendly covers Calendar sync.

Only one event type can be active at a time. You can create multiple event types, but only one booking link works simultaneously. Switching between different meeting lengths requires manually activating another event type.
