Prospeo vs SellHack: Which Email Finder Is Worth Your Money?
30-Second Verdict
We've run the numbers on both platforms, and the gap is wider than most people expect. At the $49/mo tier - the only directly comparable plan - Prospeo delivers 2,000 credits at roughly $0.0245 per credit while SellHack delivers 1,000 credits at $0.049/credit. That's double the volume for the same price.
Factor in Prospeo's 98% email accuracy and the effective cost per usable email drops near $0.01. SellHack doesn't publish an accuracy rate, and its real cost per found email runs $0.14-$0.20 depending on plan level. One is a full data platform. The other is a lightweight lookup utility.
Pricing Breakdown
SellHack tiers (monthly / annual):
| Plan | $/mo | Credits | Cost/Credit | Daily Add Limit |
|---|---|---|---|---|
| Free | $0 | 10 | - | - |
| Lite | $5 ($3 annual) | 100 | $0.050 | 100 |
| Basic | $19 ($15 annual) | 350 | $0.054 | 200 |
| Starter | $49 ($30 annual) | 1,000 | $0.049 | 300 |
| Pro | $99 ($60 annual) | 2,500 | $0.040 | 500 |
Prospeo at $49/mo: 2,000 credits, ~$0.0245/credit. The free tier alone gives you 75 verified emails plus 100 extension credits - that's 7.5x more free lookups than SellHack offers.
SellHack's credits don't roll over. If you're on the $99 Pro plan and only use 1,800 of your 2,500 credits, those 700 vanish. Reviewers flag this repeatedly. SellHack does offer non-expiring credit packs as a one-time purchase, which suits sporadic users, but if you're doing consistent outbound, the subscription math still favors the platform with twice the credits at the same price.
At $49/mo, Prospeo gives you 2,000 credits - double SellHack's 1,000. Add 300M+ profiles, 125M+ verified mobiles, Bombora intent data, and a 7-day refresh cycle. Same price, entirely different league.
Stop paying more for less data and zero accuracy guarantees.
Features That Actually Matter
| Feature | Prospeo | SellHack |
|---|---|---|
| Database size | 300M+ profiles | Not published |
| Verified mobiles | 125M+ | No dedicated mobile database |
| Native integrations | 10+ (Salesforce, HubSpot, Clay, Zapier, etc.) | Salesforce + Replyify (REST API on Pro) |
| Intent data | 15,000 topics via Bombora | None |
| Data refresh | 7 days | Not disclosed |
| Chrome extension | 40K+ users | Basic plugin; can slow or fail on some sites |
| Verification | 5-step proprietary, 98% accuracy | "12-step" (no published accuracy) |
Pick Prospeo if you need mobile numbers, intent signals, CRM enrichment, or any workflow beyond "find one email at a time." The native integrations push data into Salesforce, HubSpot, Clay, Zapier, and Make without manual exports.
Pick SellHack if you literally just need a Chrome extension to grab an occasional email and you're comfortable with a tool that won't tell you its database size or data freshness cycle. Skip it if you're running any kind of volume outbound - you'll outgrow it in a week.
Data Quality and Accuracy
Here's the thing: SellHack markets an "industry-leading 12-step verification engine" but won't publish an accuracy rate. They do provide a per-result confidence score, but without an overall benchmark, you're evaluating each email individually rather than trusting the dataset as a whole.
In our testing, Prospeo's 5-step verification with catch-all handling, spam-trap removal, and honeypot filtering catches emails that SellHack's engine misses entirely. Real customer results back this up - Meritt tripled their pipeline from $100K to $300K/week after switching, with bounce rates dropping from 35% to under 4%.
The industry guideline is to keep hard bounces under 1% (see email bounce rate benchmarks). SellHack's "100% Bounce Protection Guarantee" credits bounces back only when emails are sent through Replyify.com - not when you send from your own sequencer. That's a meaningful asterisk, and it frustrates users who discover it after the fact. The consensus on r/sales threads about email finders is that published accuracy rates matter more than vague guarantees, and SellHack doesn't give you one.
Who Should Pick What
Let's be honest: SellHack isn't really a competitor here - it's a fallback tool. TrustRadius testimonials position it as a "secret weapon" backup for when Hunter or ZoomInfo misses an email. Its G2 profile sits at 4.3/5 from just 18 reviews, the listing hasn't been active in over a year, and it has zero reviews on Capterra.
If your outbound volume is real - meaning you're prospecting daily, not weekly - the decision is straightforward. With Prospeo you get 300M+ profiles, 125M+ verified mobiles with a 30% pickup rate, Bombora-powered intent data across 15,000 topics, and a 7-day data refresh cycle. It's a pocket knife vs. a full toolkit, and the toolkit costs the same or less. If you want to pressure-test your stack, compare it against other sales prospecting databases and SDR tools before you commit.
Meritt dropped their bounce rate from 35% to under 4% and tripled pipeline to $300K/week. That's what 98% email accuracy does for outbound teams stuck on tools that won't even publish a benchmark.
Replace the backup tool with the only platform you'll need.
FAQ
Does SellHack offer a free plan?
Yes - 10 credits per month. Prospeo's free tier gives you 75 verified emails plus 100 extension credits, which is 7.5x more free lookups and matches what SellHack's $5/mo Lite plan offers. For small teams testing email finders, the free Prospeo plan covers real campaign volume without upgrading.
Can SellHack find mobile phone numbers?
SellHack lists phone numbers as a data field but doesn't have a dedicated mobile database or published coverage stats. For teams that need direct dials alongside emails, Prospeo's 125M+ verified mobile number database with a 30% pickup rate is purpose-built for that workflow.
Do SellHack credits roll over?
No. Unused credits expire every billing cycle - one of the most common complaints in user reviews. On the $99/mo Pro plan, 700 unused credits represent $28 in wasted spend each month. Over a quarter, that's $84 gone for nothing.
