Choose Apollo if
- You want one large database to search by hand: 240M+ contacts and 30M+ companies, with filters most sales teams know.
- You need a free plan that already sends email: 75 credits per seat a month, sending from Gmail.
- Calling is a big part of the job. Apollo's dialer records calls and adds AI call insights.
- You pull contact data in bulk. Per record, Apollo's own credits cost less than the same data bought through Oxygen.
