Ask what a B2B contact costs and every vendor points at a credit price. But a credit is not a contact you can use — it's a lottery ticket on one. Between the price sheet and a deliverable record sits a stack of costs most teams never total: seats you didn't need, bounces billed at full price, the cleaning tool that catches them, and the sender-reputation damage from the ones it misses.
The only number worth comparing across vendors is cost per usable contact: total spend divided by contacts that are valid, accurate, and actually in your ICP. Here's how to compute it.
Layer one: the sticker price is per credit, not per contact
Start with the obvious denominator problem. Suppose a plan costs $1,000/month for 10,000 credits — 10 cents per credit. If 15% of revealed emails bounce, you got 8,500 usable emails for your $1,000, and your real unit price is 11.8 cents. At a 30% bounce rate — common with databases verified at collection time rather than at export — it's 14.3 cents. The sticker never changed; the contact got 43% more expensive.
This is the quiet genius of pay-per-reveal pricing from the vendor's side: decay is fully priced in for them and fully externalized to you. Any vendor that charges for invalid results is charging you a hidden surcharge equal to its own database's staleness.
Layer two: seats, minimums, and expiring credits
Per-seat licensing multiplies the bill before a single record is pulled. If the data lives behind five $99 seats but only one person actually exports lists, the other four seats are pure overhead on every contact. Annual contracts with monthly credit expiry add a second tax: unused credits that vanish are spend with a denominator of zero, and most teams' usage is lumpy enough that 10–20% of credits die on the table.
Compute this layer as: (total annual cost, all seats and fees) ÷ (credits actually consumed on reveals). For many enterprise contracts that effective per-credit price is two to three times the advertised one.
Layer three: cleanup you pay for twice
If your provider doesn't verify at export, your workflow grows a mandatory second vendor: an email verification service at roughly $0.004–0.01 per check, run over every export. That's a real line item, but the bigger cost is operational — someone owns that pipeline, lists wait on it, and every handoff is a chance for a half-cleaned file to slip into a campaign.
Note what you're doing in this step: paying to find out which records you already paid for were worthless. You bought the bounce at full price, then bought the knowledge that it was a bounce.
Layer four: deliverability, the expensive one
The largest cost rarely appears on any invoice. Mailbox providers track your bounce rate, and sustained hard-bounce rates above roughly 2% start moving your mail toward spam folders. That penalty applies to your whole domain — including the messages to perfectly valid prospects. If degraded placement costs you even a handful of meetings a quarter, that dwarfs everything else in this post.
Worse, recovering a burned domain takes weeks of warm-up, and teams often respond by buying secondary domains and new inboxes — more spend caused directly by bad data. When you compare vendors, a 25% bounce rate versus a 3% one is not a data-quality footnote; it's the difference between an asset and a liability with a monthly fee.
The method: same sample, same day, full math
Vendor claims won't settle this; a controlled test will. Define one target sample — say, 500 revenue-ops leaders at 200–1,000-employee SaaS companies in the US and UK. Pull that exact definition from each vendor you're evaluating — including whichever incumbent you currently pay for — on the same day. Run every export through one independent verifier within 24 hours, and spot-check 50 records per vendor for accuracy: right person, right title, still at the company.
Then compute cost per usable contact for each: all-in monthly cost (seats, minimums, cleanup tooling) ÷ (valid × accurate contacts delivered). Expect surprises in both directions — coverage of your specific segment varies wildly between databases, which is exactly why the test must use your ICP and not the vendor's demo segment.
Where Argorant lands in this math
Argorant's pricing was designed against this equation rather than the sticker-price one. Every contact is SMTP-verified at the moment of export, invalid results cost 0 credits, and catch-all addresses are labeled and opt-in instead of silently billed as valid. That deletes layer one's bounce surcharge, layer three's second vendor, and most of layer four's risk in one move — and with plans starting under $100/month and API + MCP access on every paid plan, layer two stays small too.
But don't take the paragraph above on faith; it's a vendor talking. Put 614M contacts across 184 countries into the same-sample test against whatever you use today, divide spend by usable contacts, and let the denominator decide.
