Interseller vs WarpLeads: Which One Do You Actually Need?
Comparing Interseller vs WarpLeads is like pitting a recruiting tool in maintenance mode against a bulk lead database that costs less than your team's monthly coffee budget. These aren't competitors. They solve different problems, and both come with tradeoffs that might send you elsewhere entirely.
30-Second Verdict
Interseller is a recruiting email sequencer, now self-service at $200/seat/month with 250 lookups per user. Only worth it if you're deep in the Greenhouse ecosystem.
WarpLeads offers unlimited exports at $99/month. The volume is real. The data quality is a coin flip.
Skip both for verified contact data. Prospeo delivers 98% email accuracy across 300M+ profiles with a free tier - no contracts, no gamble.
What Each Tool Does
Interseller
Greenhouse acquired Interseller to embed sourcing automation into its ATS. By the end of 2024, Interseller fully transitioned to a self-service support model - no dedicated support team, and minor bugs don't get addressed.
You get email lookup (work and personal) through a Chrome extension or CSV import, plus email sequence sending. The Recruiter plan includes 250 lookups per user/month at $200/user/month. That's roughly $0.80 per lookup, which is steep for what you're getting in 2026.
For a recruiting team already inside Greenhouse, the embedded functionality adds value. As a standalone purchase? Don't bother.
WarpLeads
WarpLeads bills itself as "the only lead database with truly unlimited exports." For $99/month flat, you get access to 100M+ people and 20M+ companies with unlimited contacts and exports per month. There's also a free plan: 30 contacts/month, 30 exports/month, filters, unlimited lists, unlimited users, exclude lists, CSV export, and de-duplication.
It's built like a raw database - filters including technographics, bulk lookup, de-duplication, and CSV export. An API is also available.
Here's where it gets interesting. WarpLeads lists "Additional Contact Exports" add-ons with tiered pricing, even alongside the "unlimited exports" plan. That contradiction is worth noting before you commit, especially since they operate a no-refund policy.
WarpLeads claims "80M+ verified leads" on their site. We've tested enough B2B databases to know that "verified" means wildly different things depending on who's saying it - and the Reddit evidence below tells the real story.
WarpLeads needs a separate verifier. Interseller charges $0.80 per lookup. Prospeo finds and verifies in one step - 300M+ profiles, 98% email accuracy, 7-day data refresh. Starting at $0.01/email with a free tier.
Skip the verification duct tape. Get emails that land.
Side-by-Side Comparison
| Feature | Interseller | WarpLeads | Edge |
|---|---|---|---|
| Primary use | Recruiting outreach + sequences | Bulk B2B lead database | Depends on role |
| Price | $200/user/mo | $99/mo flat | WarpLeads |
| Email lookups / exports | 250 per user/mo | Unlimited exports | WarpLeads |
| Email sequences | Yes | No | Interseller |
| Chrome extension | Yes | Yes | Tie |
| Integrations | Greenhouse + ATS/CRM | CSV export + API | Depends |
| Support model | Self-service (no dedicated team) | Helpdesk-style | WarpLeads |
| Data verification | Built-in email verification | Quality varies; external verification recommended | Interseller |
| Cost per record | ~$0.80 per lookup | Near-$0 at volume (quality varies) | WarpLeads on paper |
The cost-per-record contrast is stark. But "free per record" means nothing if the data isn't usable. You're trading cost for quality assurance, and that tradeoff bites harder than most people expect.
The Data Quality Problem
$99 for unlimited exports sounds too good to be true. The question keeps coming up on r/coldemail, and the answers are split.
One user on r/Emailmarketing called WarpLeads quality "terrible - high bounce rate, old emails" even after verifying with Apollo and removing unverified records. They still ended up with unacceptable bounce rates. When a second verification layer can't save the data, the underlying records are stale.
But we've also seen the opposite. A user on r/SaaS shared a detailed workflow: WarpLeads exports verified with Reoon, domains warmed on Mailforge, sent via Smartlead. The result - 2,200 emails, 65 replies, 18 demos, 8 paying customers adding ~$2,100/month in MRR. The difference? A dedicated verification step and careful list hygiene.
Here's the thing: WarpLeads at $99/month plus a $30-50/month verifier still costs less than one Interseller seat. If you're willing to build the workflow, the math works. But if your time is worth anything, paying for pre-verified data saves hours every week. Our team ran a similar comparison internally, and the manual verification step added roughly 3-4 hours per week to the process - time that compounds fast when you're scaling outbound.
Who Should Use What
Use Interseller if you're a recruiting team already on Greenhouse and the embedded sourcing tools cover your workflow. Don't buy it standalone - $200/seat for 250 lookups with no dedicated support is indefensible in 2026.
WarpLeads makes sense when you're scaling outbound list building on a tight budget and you'll pair it with a separate verifier. Budget $99 plus your verification tool, and accept the extra workflow step.
For teams that need verified data without the duct tape, Prospeo gives you 300M+ profiles at 98% email accuracy with a 7-day data refresh cycle, 125M+ mobile numbers, and native integrations with Smartlead, Instantly, Lemlist, and HubSpot. Free tier to test, no contracts, and no need to chain three tools together. Teams like Snyk cut bounce rates from 35-40% to under 5% and grew AE-sourced pipeline 180% after switching - that's the gap between pre-verified data and the verify-it-yourself approach.
Snyk's 50 AEs cut bounce rates from 35-40% to under 5% and grew pipeline 180% with Prospeo. No chaining tools, no stale data, no $200/seat recruiting tax. Just pre-verified contacts across 300M+ profiles.
One platform. Pre-verified data. Zero extra workflow steps.
FAQ
Is Interseller shutting down?
There's no announced shutdown date, but Interseller fully transitioned to self-service support by end of 2024 - no dedicated team, and minor bugs go unpatched. It's alive but functionally in maintenance mode. Recruiting teams still on Greenhouse can use it; everyone else should look elsewhere.
Is WarpLeads data accurate?
Accuracy is inconsistent. Some users report high bounce rates and stale emails even after third-party verification, while others run successful campaigns by pairing WarpLeads exports with dedicated verifiers like Reoon. Always verify before sending - never trust "unlimited" data at face value. The r/coldemail community has extensive threads on this if you want to dig deeper.
What's a good alternative to both tools?
Prospeo offers 300M+ profiles with 98% email accuracy, 125M+ verified mobiles, and a free tier at 75 emails/month with no contracts. It handles finding and verification in one platform with a 7-day data refresh cycle, so you skip the extra verification step WarpLeads requires and the per-seat cost Interseller charges. ZoomInfo is another option if budget isn't a concern, though you'll pay roughly 90x more per lead.
