ContactOut vs SellHack: The Honest Comparison
If you're weighing ContactOut against SellHack for your prospecting stack, the answer is straightforward. ContactOut wins - bigger database, broader integrations, active development signals. SellHack is cheaper at $5/mo but shows every sign of a product in maintenance mode.
Let's break this down so you can stop second-guessing and pick the right tool.
ContactOut vs SellHack at a Glance
| Feature | ContactOut | SellHack |

| Starting price | $49/mo (billed annually) | $5/mo |
| Free trial | 15 credits/day | None |
| Integrations | Salesforce, HubSpot, Zoho, Greenhouse, Lever | Replyify + Salesforce (Pro only) |
| Browser support | Chrome extension | Chrome, Firefox, Safari |

What Is ContactOut?
ContactOut runs an 800M+ profile database with 400M+ emails - one of the larger email finders outside the ZoomInfo/Apollo tier. The Chrome extension surfaces work emails, personal emails, and phone numbers directly from professional profiles, and the platform integrates with Salesforce, HubSpot, Zoho, Greenhouse, and Lever. That makes it a strong fit for both sales and recruiting teams.
ContactOut ran its own benchmark across 12 tools and 200 SaaS decision-maker profiles: 90% valid emails, 2.5% invalid, and 15 not found. That's a vendor-run test, sure, but it's more transparency than most competitors bother with.
The frustrating part: ContactOut's pricing page shows "Talk to us" placeholders instead of actual numbers. In practice, plans typically land around these tiers:
- Email: $49/mo (billed annually) - marketed as "unlimited" but capped at 2,000 email credits/month with 300 exports/month
- Email + Phone: $99/mo (billed annually) - 2,000 emails/month and 1,000 phone credits/month with 600 exports/month
- Team/API: custom pricing
Use this if you're a recruiter or sales rep who needs a large database with ATS/CRM integrations and doesn't mind navigating opaque plan limits. If you're building a broader outbound stack, compare it against other options in our guide to SDR tools.
What Is SellHack?
SellHack launched in 2014 as an all-in-one prospecting tool - find emails, build lead lists, verify addresses, and sync with Salesforce. It also includes pipeline/task management and one-click email integration so you can send cold emails and follow-ups directly from your own inbox. Bulk email verification via CSV upload, an X-Ray Search Engine, and a browser plugin for recruiting round out the feature set.
SellHack markets a 12-step, real-time email verification engine that finds the best email address in a few seconds. The browser extension works across Chrome, Firefox, and Safari - genuine multi-browser support that ContactOut doesn't match.
Here's the thing, though. SellHack has serious maintenance-mode signals. Tracxn lists one employee as of mid-2024. The latest funding is a Feb 2015 grant. And its G2 page shows a banner indicating the profile hasn't been active for over a year. On Capterra, SellHack currently shows zero reviews and no free trial.
G2 reviewers who do like SellHack praise ease of use and the speed of finding verified emails, but they also flag inconsistent coverage for smaller and international companies and a browser extension that can be slow or fail outright.
One more catch: the "100% bounce protection guarantee" only applies if you send through Replyify.com. Send through anything else and you're on your own. If deliverability is a priority, it’s worth understanding email bounce rate benchmarks and what actually causes spikes.
SellHack only makes sense if you need the absolute cheapest email finder at $5/mo and you're comfortable with the risk of limited support and uncertain product longevity. We wouldn't recommend it for any team running serious outbound volume.
ContactOut caps you at 2,000 emails/mo with opaque pricing. SellHack shows every sign of a dying product. Prospeo gives you 300M+ profiles at 98% email accuracy, refreshed every 7 days - for roughly $0.01 per email. No "talk to us" gates, no annual contracts.
Stop overpaying for stale data from tools that might not exist next year.
Pricing Breakdown
SellHack's pricing is transparent. ContactOut's isn't.
| Plan | SellHack (monthly) | SellHack (annual) | Credits |
|---|---|---|---|
| Lite | $5/mo | $3/mo | 100 |
| Basic | $19/mo | $15/mo | 350 |
| Starter | $49/mo | $30/mo | 1,000 |
| Pro | $99/mo | $60/mo | 2,500 |
Credits don't roll over. The Pro plan unlocks REST API access and Salesforce integration.
ContactOut is commonly packaged around $49/mo for Email and $99/mo for Email + Phone (billed annually), with caps like 2,000 email credits/month and 300-600 exports/month depending on the plan.
Cost per email at scale:
- SellHack - ~$0.04-$0.05/email at Starter-Pro tiers
- ContactOut - ~$0.025/email at the 2,000-email cap on the Email plan
- Prospeo - ~$0.01/email on paid plans, with 98% verified accuracy

The Verdict
Between these two, ContactOut is the only viable pick. The ATS integrations and larger database make it the clear winner, and if you're in recruiting, Greenhouse and Lever support seals it. We've seen teams adopt bargain-bin tools like SellHack, then scramble six months later when the extension stops updating or verification quality degrades. That's not a hypothetical - it's a pattern.

Look, if you're comparing these two in 2026, you're probably looking at the wrong shortlist entirely. The most recent SellHack mention we found on r/sales dates to 2016. That tells you everything. For a more tactical approach to building pipeline, use these sales prospecting techniques.
A Better Third Option
For context on what that accuracy difference means in practice: one of our customers, Snyk, dropped their bounce rate from 35-40% to under 5% after switching, and their AE-sourced pipeline jumped 180%. Bad data doesn't just waste credits - it burns your sender reputation. If you’re trying to protect deliverability long-term, read how to improve sender reputation.
Snyk's 50 AEs cut bounce rates from 35-40% to under 5% and grew AE-sourced pipeline 180% - because verified data actually connects you to real buyers. Prospeo's 5-step verification and 7-day refresh cycle deliver what ContactOut and SellHack can't.

FAQ
Is SellHack still actively maintained?
SellHack's website is live and accepting signups, but its G2 profile hasn't been active for over a year. Tracxn lists one employee as of mid-2024, and the latest funding is a Feb 2015 grant. There's no free trial available. Proceed with caution - the product shows clear maintenance-mode signals, and you won't have much support if something breaks.
Does ContactOut show pricing on its website?
Not clearly. ContactOut displays "Talk to us" placeholders instead of readable plan prices. In practice, expect ~$49/mo for Email and ~$99/mo for Email + Phone (billed annually), with caps around 2,000 email credits/month and 300-600 exports/month depending on plan tier. You can also check G2's ContactOut pricing page for user-reported figures.
