The Chrome extension is where most efficient Hunter prospecting happens. It surfaces emails on LinkedIn, company sites, and any page — without leaving the browser. This walks through setup and the workflows that save real time.
Who this is forSDRs and founders prospecting on LinkedIn. If you spend 4+ hours/week looking up emails after finding people on LinkedIn, the extension cuts that to 1 hour.
What you'll need
Step 1
Open Hunter dashboard → "Get the Chrome Extension." Click "Add to Chrome." Confirm permissions.
In your Hunter dashboard, click the "Chrome Extension" link in the top navigation.
Click "Add to Chrome." Confirm the permissions dialog.
The Hunter icon (yellow H) appears in the Chrome toolbar.
Pin it to your toolbar (right-click → Pin) so it is always visible.
Step 2
Click the Hunter icon → Sign in. Authenticates against your existing Hunter account. Pulls your team credits.
Click the Hunter icon in the toolbar.
Click "Sign in." Enter your Hunter credentials (or "Sign in with Google" if linked).
Once signed in, the extension shows your remaining credits in the top corner.
Each team member installs and signs in separately.
Step 3
On any LinkedIn profile, click the Hunter icon. Extension surfaces likely emails for that person, with confidence scores.
Open any LinkedIn profile.
Click the Hunter icon in the toolbar (or look for the Hunter button injected next to "Connect").
The extension shows: most-likely email + confidence + verification status, plus the company pattern.
Click "Save to Leads" to add to a Hunter list without leaving LinkedIn.
Costs 1 search credit per profile-lookup. Free if no email is found.
Step 4
On any company website, click the Hunter icon. Extension lists all emails Hunter has indexed for that domain.
Visit a company website (e.g., stripe.com).
Click the Hunter icon.
Extension displays all known emails for the domain, with department + seniority badges.
This is the equivalent of running Domain Search but without leaving the site.
Click any email to verify or save to Leads.
Step 5
Most teams under-utilize the extension. Schedule a 30-min training: LinkedIn prospecting → extension → Leads list → outreach tool.
Schedule a 30-minute team training. Walk through:
1. LinkedIn search for an ICP role.
2. Open 5 profiles, use extension on each.
3. Save to a named Leads list.
4. Export list to outreach tool (Lemlist, Instantly, Smartlead).
5. Discuss: which results were high-confidence vs. low? How does the team handle low?
Without training, reps default back to manual lookups. The extension's value is the workflow, not the install.
Common mistakes
Installing but not using it on LinkedIn
What goes wrong: Reps spend 3-4 hours/week looking up emails after finding people on LinkedIn. With the extension, this drops to 30-60 min. ~2-3 hours/week per rep wasted.
How to avoid: 30-minute team training. Make the extension the default LinkedIn prospecting tool.
Not pinning the extension to the toolbar
What goes wrong: Reps forget the extension exists because it is hidden in the extensions menu. Manual lookups continue. The investment in installing is wasted.
How to avoid: Right-click the Hunter icon → Pin. Make it visible in every Chrome window.
Saving every result to one massive Leads list
What goes wrong: All prospects go to one list. CRM segmentation is impossible. Email-sequence personalization is impossible.
How to avoid: Create named Leads lists by campaign/ICP/cadence. Save to the relevant list, not a default catch-all.
Ignoring the verification step in-extension
What goes wrong: Reps save to Leads without verifying. Outreach campaigns send to unverified emails. Bounce rate climbs.
How to avoid: Verify before save. The extension surfaces a verify button on every email result — use it.
Not training new hires on the extension
What goes wrong: New rep joins, does prospecting manually for 3 months before someone shows them the extension. ~30 hours of wasted time per new hire.
How to avoid: Add Hunter extension training to onboarding. Day 1.

Hand it off
Using the extension is a skill. Building a full demand-gen pipeline from LinkedIn → Hunter → outreach is a job. A vetted specialist will set up the workflow + train the team. From $14-16/hr.

Works on any Chromium-based browser: Brave, Edge, Arc, Opera. Firefox extension exists but is feature-limited.
Yes — 1 search credit per profile lookup that returns an email. Free if no email found. Verification costs 1 verification credit per check.
The extension surfaces emails relevant to the specific page (LinkedIn profile or company subpage). Domain Search shows ALL company emails. Both are correct, just different scopes.
Right-click the icon → Manage extension → Site access. Allow only on specific sites if you want to disable it elsewhere.
LinkedIn has historically been ambiguous. Hunter does not scrape — it shows you data Hunter already has, surfaced based on the page you are viewing. Use reasonably (no bulk scraping) and you are within ToS.
Hunter.io
Hunter.io is the most-used email-finder in B2B outbound — and the easiest to misuse. This walks through the right setup path: plan choice, team workspace, integration baseline, and the credit-usage rules most teams learn the expensive way.
Hunter.io
Email Finder is the 'I know who I want to email — find their address' tool. It is more accurate than guessing patterns by hand, and the verification step is what separates a 95% deliverable list from a 65% deliverable one.
Hunter.io
Bulks is where Hunter actually pays for itself. Find emails for 500-5,000 names in 30-60 minutes. This walks through the CSV format, processing time, credit math, and the cleanup pass.
Hunter.io
DIY cold email is great — until reply rate caps at 1.5% and you cannot tell why. Here is the honest framework: when the cost of self-managing exceeds the cost of hiring.
