Every B2B data provider's pricing page looks reasonable in isolation. The real cost only becomes clear once you compare what a contact actually costs once credits, accuracy, and add-ons are factored in — and that number varies far more than most buyers expect.
The Cost Per Contact Is Not What's on the Pricing Page
The effective cost per contact ranges from $0.01 on high-volume platforms like Apollo.io to over $1.50 on enterprise providers like ZoomInfo once add-ons and limited export allowances are factored in. Apollo's Professional plan gives 10,000 emails per month at $99/user, working out to roughly $0.01 per email. Lusha, by comparison, charges $59/month for 160 credits — about $0.37 per contact, a 37x difference for what looks similar on a feature comparison page.
Credit-based pricing creates hidden costs. Sales reps tend to hoard credits early in the month, then burn through them at month-end to hit quota, while RevOps teams spend hours managing credit allocation across seats instead of optimizing pipeline.
Data Decays Faster Than Most Contracts Account For
B2B contact databases decay at roughly 2.1% per month, or about 22.5% annually — meaning nearly a quarter of the contacts paid for today will be outdated before the next contract renewal.
Cognism's own decay research shows email addresses decay 23–30% annually and phone numbers change at roughly 18% per year — buy 10,000 contacts in January, and roughly 2,300 of those emails are invalid by December.
Renewal terms compound this. ZoomInfo contracts typically include 10–20% automatic price increases at renewal, turning a $25,000/year contract into $30,000 by year three without adding a single seat or feature.
Database Size Is the Least Useful Number on Any Pricing Page
Large contact databases make for impressive marketing, but they don't tell you how useful the data will be in practice. What matters is how much of that data is accurate, up to date, and relevant to your target market.
In reality, buyers often find that a sizeable portion of exported lists contains outdated contacts, missing information, or records that don't match their ideal customer profile. A database with millions of contacts is far less valuable if your team spends hours cleaning lists before they can start prospecting.
What Differentiates the Major Providers
Apollo.io is the cheapest entry point with the most generous free tier and fully public pricing, making it the best fit for budget-conscious SMB and early-stage teams. The trade-off is data accuracy that requires independent verification before relying on it for high-volume cold calling.
ZoomInfo offers the most comprehensive B2B database, especially for US direct phone numbers, but comes with enterprise pricing, complex contracts, and a steeper learning curve — best suited to organizations with the budget and RevOps headcount to manage it properly.
Cognism is the UK and EU compliance leader with the best verified mobile data, though pricing is opaque, with estimated annual costs ranging from $1,500 to $25,000+ for the Platinum tier.
Lusha is the lightest option, designed primarily for quick contact lookup and enrichment rather than building targeted lists from scratch — a fit for individual reps enriching contacts they've already found elsewhere.
How to Evaluate a Provider Before Buying
- Test on your real ICP, not a demo list. Pull a sample of 50–200 contacts matching your actual target accounts and check accuracy yourself rather than trusting a vendor's stated percentage.
- Calculate true cost per usable contact, not per credit — factor in the accuracy rate, since a $0.37 contact at 95% accuracy can be cheaper than a $0.01 contact at 65% accuracy once wasted outreach is accounted for.
- Check what's NOT included — sequencing, deliverability infrastructure, and CRM sync are frequently separate purchases even when a provider's homepage implies otherwise.
- Confirm renewal terms before signing, specifically any automatic price escalation clauses.
- Match regional coverage to your actual pipeline — a US-strong database is a poor fit for a UK/EU-heavy sales motion, and vice versa.
Time to Make a Decision
Most B2B data providers help you find contacts. The next steps — knowing when to reach out and managing the outreach itself — often require additional tools. Platforms like Zileo take a different approach by combining live buying signals, contact discovery, and multichannel sequencing in one place, reducing the need to stitch together multiple systems.
Why Zileo is the Best Choice
Whether you're comparing platforms or scaling your outreach, one thing is clear: the agencies and sales teams that move fastest win the most business. Zileo gives you the speed, coverage, and automation to stay ahead.
