MoltSets for LinkedIn by MoltSets

MoltSets for LinkedIn: enrich any LinkedIn profile in one click.

Open someone's LinkedIn profile, open the MoltSets sidebar, and pull verified contact data for that person straight from the MoltSets database: their business email with a deliverability grade, a full business profile, and a carrier-verified mobile number.

Built for salespeople, recruiters and founders who already prospect on LinkedIn and want accurate contact details without copying, pasting or switching tabs.

WHAT YOU GET

• Business email, graded for deliverability
Every email comes with a risk grade, so you know whether it's safe to send:
A – validated deliverable
B – known engagement
C – catch-all domain, deliverability unknown
D – do not send
F – unverified
You also see the date it was last validated.

• Full business profile
Name, job title, seniority, function, location and time in role, plus company details: company name, website, LinkedIn company page, industry, employee count and revenue range. The business email comes with the same lookup.

• Carrier-verified mobile numbers
Numbers are verified with the carrier, and only mobile numbers are returned, so you won't get desk lines. Mobile lookups are available on paid plans with a phone token subscription. One phone token is used per number found, and a lookup that finds nothing is free.

• Personal email as a fallback
If there's no business email and your plan includes personal emails, the profile lookup shows the personal addresses on file instead.

HOW IT WORKS

1. Install the extension and click the MoltSets icon in your toolbar to open the sidebar.
2. Connect your MoltSets API key, or sign up for free.
3. Open any LinkedIn profile. The panel recognises it from the page address.
4. Click "Get full profile", "Get email only" or "Get mobile". Results appear in seconds.

The sidebar stays open as you move from profile to profile, so you can work through a list without reopening anything.

YOU STAY IN CONTROL OF WHAT YOU SPEND

• Nothing is looked up automatically. Every lookup starts with your click.
• Lookups that find nothing don't use tokens.
• Results are saved in your browser. When you come back to a profile you've already enriched, your data is waiting and you don't pay to look it up again. Refresh it whenever you want the latest data.
• Your usage is always visible at the top of the panel: free tokens remaining on the free plan, or your fair use for the last 5 hours and the week on paid plans.
• The account panel shows your plan, phone token balance and when your limits reset. It updates as you browse, so an upgrade shows up straight away.

KEEP TRACK OF EVERYONE YOU'VE ENRICHED

• The Enriched profiles list shows everyone you've looked up, most recent first, with what was found for each person.
• Search by name, company or email.
• Download a single profile or your whole list as a CSV file that opens cleanly in Excel or Google Sheets and is ready to import into your CRM.
• Delete profiles one at a time or in bulk whenever you like.

PRIVACY, AND HOW THE EXTENSION USES LINKEDIN

The MoltSets Firefox Extension does not scrape information from LinkedIn. It only enriches LinkedIn URLs with data from MoltSets' database using our APIs.

• The only thing the extension reads from LinkedIn is the address (URL) of the profile in your active tab, so it knows which profile you're viewing. It doesn't read the page's content, and it doesn't add anything to LinkedIn pages.
• When you click a lookup, the extension sends that profile URL to the MoltSets API along with your API key. Nothing is sent until you click.
• Your API key and your saved results are stored locally in your browser. They aren't synced to other devices, and you can delete them at any time. Your API key is locked with a passphrase you choose, so it's stored encrypted. Signing out removes your API key.
• The extension contains no analytics or advertising code.

Permissions the extension asks for:
• Storage: keeps your API key and saved results on your device.
• Sidebar: MoltSets opens in the Firefox sidebar, beside the page you're viewing. This needs no extra permission.
• Access to linkedin.com: used only to read the address of your active tab, so the panel can tell when you're on a profile.
• Access to api.moltsets.com: runs the lookups you ask for.

PRICING

Everybody starts free with 1,000 API calls. After that, MoltSets plans start at $27/month for unlimited access to core data, with fair use limits sized to each plan and no per-lookup credits. Mobile numbers use phone tokens, a monthly add-on available on paid plans. See plans at moltsets.com/pricing.

MORE THAN A LINKEDIN EXTENSION

The same data is available through the MoltSets API and MCP server. Enrich whole lists, search for people and companies, and connect tools like Claude, ChatGPT and Clay.

USING CONTACT DATA RESPONSIBLY

You're responsible for using contact data in line with the laws that apply to you, such as GDPR, CAN-SPAM, CASL and the TCPA. Mobile numbers aren't screened against Do Not Call registries, so check them before you call or text.
