The bottom line on Apollo.io.
Apollo is our primary prospecting database. The combination of data breadth, built-in sequencing, and price makes it hard to beat for most B2B use cases. We use it mainly for data and export to Instantly/Smartlead for sending, but the built-in sequences work fine for simpler campaigns.
Best for
- ✓Teams needing data + sequencing in one platform
- ✓Startups and SMBs on a budget
- ✓SDR teams doing high-volume prospecting
Not for
- ✕Enterprise teams needing GDPR-strict European data
- ✕Companies needing phone-verified mobile numbers
