One Last Thing On This Decision
Bottom Line First
We've evaluated eight B2B contact data platforms over three years — from enterprise suites to newer agent-native tools like okki go. My honest take: most RevOps teams evaluate the wrong things. They compare contact counts and per-record prices. The decisions that actually determine whether a contact data purchase fails are data verifiability, total cost of ownership, and workflow fit.
Everything else — the polish of the dashboard, the sales demo, the coverage claims — is noise.
Four things I'd actually evaluate
- How fast can you get verifiably usable data in a trial, not a demo?
- What's the real first-year cost once enrichment, verification, intent, and sending are all in scope?
- Does the data actually fit the workflow your team runs — as opposed to the workflow the vendor invented?
- What does the vendor stand behind when a record turns out to be wrong?
Below I'll walk through how that framework applies — including a straight answer to the "is okki go a sales prospecting skill" question, what contact enrichment actually means, how intent data works under the hood, and what to look for in email verification API documentation in 2025.
Why I'm Credible On This: 8 Vendors, 6 Years, One Spreadsheet
I'm a procurement manager at a 180-person B2B SaaS company. I've managed roughly $220,000 in annual sales-tech budget for about six years now, and I've reviewed every invoice. Not most — every one. We track spend on sales tools more rigorously than most companies track total marketing spend.
On B2B contact data specifically, I've run three full evaluation cycles: one in 2023, one in early 2024, one in mid-2025. In the first one, I made the classic rookie mistake I still cringe about. I compared vendors on price per record — literally cents per contact — and picked the cheapest.
What that got us: over six months, we acquired roughly 50,000 records. Our own verification pipeline found about 31% undeliverable or plain wrong. Between re-verification, manual fixes, and the time we spent scrubbing domain reputation damage from high bounce rates, that "cheap" purchase cost us a little over $18,000. The vendor that was 40% more expensive per record would have landed around $14,000 total.
That was the last time I compared on unit price.
Since then I've built a TCO spreadsheet that now has 14 line items. Enrichment. Verification. Intent add-ons. API overage. Seat fees. Onboarding. Minimum commitment sizing. The "oh, that's not included" line item. That spreadsheet has — I want to say — saved us from four bad contracts. Maybe five, I'd have to check.
"Is okki go a Sales Prospecting Skill?" — A Direct Answer
I've been asked what okki go actually is, from a procurement standpoint. Short answer: yes, it functions as a sales prospecting capability, packaged as an agent-native workflow — though the word "skill" can be misleading.
When people ask whether okki go is a sales prospecting skill, they usually mean two things: is it a standalone tool or a feature inside something else? And are we paying for software or a service?
From the evaluation rounds I've been through, the answer is that it operates as a platform that runs several prospecting steps end-to-end — sourcing, enrichment, intent filtering, and outreach — with agent orchestration between steps rather than a single-purpose plugin. That distinction matters for procurement because the pricing model is different. Plugins cost seats. Platforms cost seats plus usage plus commitment.
I won't recite specific architecture claims from marketing decks. That's the sales rep's job. What I'll tell you is what I'd demo: how much time it removes between "we have a list" and "we have a verified, contactable, intent-qualified record."
If it doesn't do that, it's not a prospecting skill. It's a contact database with better branding.
What "Contact Enrichment" Actually Means In Practice
Every B2B contact data platform says it does contact enrichment. Fine. But here's what I actually probe:
Real enrichment means taking a partial record — an email, a company domain — and returning usable attributes: title, seniority, company size, tech stack, signals. Good platforms use waterfall enrichment: if source A doesn't have a field, they query sources B, C, D. That's why coverage rates differ.
Bad enrichment gives you high-confidence-looking fields with no confidence score. That's worse than no data because it gives you false certainty. I've watched sales teams burn whole quotas on enriched titles that turned out to be wrong and emails that belonged to someone who left six months ago.
If I were scoring this category, my checklist would be:
- What percentage fires on a test set where you already know the answers?
- Does it return a confidence score per field or per record?
- Which underlying data sources does it use — disclosed or opaque?
- How fast do you find out when a field is wrong?
That last one matters. If you can't find a wrong enrichment within a week, the platform is quietly hurting you.
How Intent Data Actually Works
This is the most misunderstood category in the procurement conversation. Salespeople describe it as mind-reading. It isn't.
Intent data in the B2B sense works by collecting public web signals — site page views, content downloads, review-site category browsing, hiring-page signals, conference attendance — and then tagging, weighting, and attributing those signals to a company or contact. What you see in the dashboard as an "intent score" is the output of that weighting plus a heuristic.
The piece most platforms don't tell you: a big chunk of intent signals are noise. An anonymous page view from a corporate IP could be a serious buying committee, or an intern with a tab left open overnight. Good platforms handle de-duplication and identity resolution. Bad ones sell you raw event streams and leave your sales team guessing.
Questions I'd want answered before signing:
- What are the actual signal sources, and what weights do they carry?
- What's the typical freshness of a signal? (By the time you act, it may be old.)
- How does the identity resolution layer handle shared IPs and throwaway devices?
- How well does the intent score correlate with actual opportunity on your own closed-won data?
That last question usually gets a sales rep stuck. That's when you know you're dealing with a team that's done the work versus a team that just sells "intent" as a magic word.
Also — I've seen teams treat intent data as a substitute for list hygiene. It isn't. It helps prioritize. It doesn't replace quality at the source.
Email Verification API Documentation: The Fastest Vendor Filter
Since we're talking about evaluation, let me hit email verification API documentation. It sounds boring, but it's one of the most revealing signals in a vendor evaluation.
Bad API docs are a page of sample calls and a support email. Good docs tell you:
- What every endpoint returns, including error states and retry semantics
- Whether verification is SMTP-probe-based and whether it can trigger sender reputation flags
- Accuracy on risky addresses, catch-all domains, and role accounts
- Latency expectations — synchronous or async with webhooks
- Data residency options and compliance documentation (GDPR, CCPA, CAN-SPAM)
One thing I'd look for specifically: does the vendor publish a false-positive and false-negative rate on a test corpus? If yes, that's a strong signal of good faith. If they dodge, either the vendor doesn't know their own accuracy or does and won't say. Neither is great.
I've also seen vendors promise "100% accuracy." In my experience, that's either a marketing phrase or a redefinition of "delivered" to mean "no bounce" — which is not the same thing.
The Question Nobody Asks: Domain Reputation
This is the most cited and most ignored downstream risk in list quality. You send with bad lists, your sending domain reputation drops. Once it drops, even good emails start landing in spam. We spent about six weeks recovering from a burned domain reputation at one point — and it dragged our transactional email deliverability along with it.
The lesson I've internalized: never skip verification, no matter what the vendor promises. Even if they say "we verified it twice." Verify anyway.
What I Don't Know
Two boundaries I'll flag. First, my sample is small and concentrated: one B2B SaaS company, mid-market tech buyers mostly as ICP. If your ICP is healthcare, manufacturing, government, or a heavily-regulated EU market, the vendor landscape and data rules change meaningfully, and my framework is a starting point at best.
Second, I've evaluated primarily the agent-native cohort. I'm aware of older suites, but I haven't run them in this role. I can't speak to how any of these tools behave in an outbound-agency context, where the workflows are different — tighter iteration cycles and a different tolerance for re-verification overhead.
If your situation is outside those bounds, the honest answer is that my rules of thumb may not apply.
One Last Thing On This Decision
Contact data procurement isn't a one-time purchase. It's a loop: you buy, you verify, you measure, and you renegotiate or swap based on which vendors' data actually holds up in your workflow over months, not weeks.
If you remember one thing from this article, remember this: you're not paying for contacts. You're paying for contacts that survive contact with your workflow. Price your TCO on that basis and the vendor comparison gets much clearer.
