Which one to pick

Choose Apollo if

  • You want one tool for the data, the sequences and a CRM, priced per seat.
  • You want a listed price with no sales call at every tier up to Organization.
  • You want mobile phones on a self-serve plan (8 credits per phone).
  • You want people search at 0 credits on paid plans to size lists before enriching.

Choose ZoomInfo if

  • You want to pay only for data you enrich, with no seats: top-ups from $20.
  • You want free search, lookup and lookalike calls before spending a credit.
  • You need intent topics, scoops, org charts or corporate hierarchy, and can buy the Enterprise or Intent options.
  • You want larger enrich batches: 25 records per API call.
  • You want a higher default rate limit: 25 requests a second on the Standard tier.

If neither fits: If you only need work emails for a list you already have, a dedicated email finder that charges only on a found email may cost less than either database.
