We rate Apollo.io 4.3/5. Generous free tier (10,000 email credits/month), making it especially useful for solopreneurs and startups. The main tradeoff: data accuracy varies by region. The free tier softens this considerably.
About Apollo.io
Apollo.io is a sales intelligence and engagement platform combining a B2B contact database with email outreach tools. It's become the go-to prospecting tool for startups and sales teams.
The Free plan includes 10,000 email credits/month, basic sequences, and 60 mobile credits/year. Basic ($49/user/month) adds advanced filters, A/B testing, and buying intent signals. Professional ($79/user/month) adds dialer, advanced reports, and AI-assisted emails.
Apollo's database contains 275+ million contacts with verified emails, phone numbers, company data, and job titles. The Chrome extension reveals contact info on LinkedIn profiles. Sequences automate multi-step outreach campaigns.
For solo founders doing outbound sales, the free tier provides 10,000 email lookups monthly — enough to build a substantial prospect list. Combined with sequences, you can run automated outreach campaigns at scale.
Limitations: data accuracy varies (expect 80-90% email accuracy), free tier has limited sequences, and aggressive outreach can hurt deliverability. Use thoughtfully with targeted, relevant messaging.
