Reviews
Apollo.io
Apollo.io folds a 275M-plus contact database, enrichment, and a sequencer into one login, and the free tier is real. But the data is 65-70% accurate, 'unlimited' has a hard ceiling, and the annual contract wants 60 days' notice to leave.
Free plan (unlimited email credits at fair-use limits, plus 5 mobile and 10 export credits/mo, 2 sequences); Basic $49, Professional $79, Organization $119 - per user/mo billed annually (Organization needs 3+ seats), 20-25% more month-to-month ($59/$99/$149). Credits expire at cycle end; no rollover
Clay
Clay is a spreadsheet-shaped orchestration layer that runs waterfall enrichment across 100+ data providers and AI. Best-in-class at that job - but credit rollover is capped at 2x, most teams pay ~3x the headline, and the learning curve is steep.
Free (100 data credits + 500 actions/mo); Launch $185/mo (~$167 annual), Growth $495/mo (~$446 annual), Enterprise custom. Two currencies: Data Credits (buy data) + Actions (run the workflow). Data credits roll over but cap at 2x monthly (5,000 Launch / 12,000 Growth); actions never roll over; mid-cycle top-ups carry ~30% markup
Hunter.io
Hunter.io does two things well: find a business email from a domain and verify whether it is deliverable. The only pricing here you can predict to the dollar - but the confidence score lies on catch-all domains, and there is zero phone data.
Free (50 credits/mo); Starter $34/mo, Growth $104/mo, Scale $209/mo billed annually (monthly is ~40% more: $49/$149/$299) for 2,000/10,000/25,000 credits/mo; 1 credit = 1 email found, 0.5 credit = 1 email verified; unlimited team seats share the pool; monthly credits do not roll over; cancel any time, no annual lock-in
Instantly
Instantly sends cold email at scale - unlimited inboxes, automated warmup, one shared reply box. It does that job well, but the lead database and CRM bill separately, warmup is no deliverability guarantee, and the legal risk is yours, not the tool's.
Sending: Growth $37.60/mo annual ($47 monthly; 5,000 emails, 1,000 contacts), Hypergrowth $77.60/mo annual ($97 monthly; 100,000 emails, 25,000 contacts), Light Speed $286.30/mo annual ($358 monthly). Lead database (SuperSearch) $47-197+/mo and CRM $47-97/mo bill SEPARATELY, so a working stack usually lands ~$130-250+/mo (SDR teams report $200-400). 14-day trial, no permanent free tier
