MoltSets finds verified business emails, personal emails and carrier-verified mobile numbers for the LinkedIn profile you're viewing. Every email is graded A to F for deliverability, so you know what's safe to send before you send it. Start free with 1,000 lookups. Paid plans start at $27/month with no per-lookup credits, and lookups that find nothing are always free. The extension never scrapes LinkedIn. It reads only the profile URL in your active tab and looks it up in the MoltSets database, so your account isn't put at risk. Built for salespeople, recruiters and founders who want accurate contact details in the tools they already use. WHY MOLTSETS • A deliverability grade on every email, with the date it was last validated • Mobile numbers verified with the carrier, and mobiles only, so no desk lines • No per-lookup credits on paid plans, with fair use limits sized to your plan • You never pay twice: enriched profiles are saved in your browser and reopen for free • Lead lists, CSV export and one-click sending to your CRM or workflows, included on every plan HOW IT WORKS

Click the MoltSets icon in your toolbar to open the sidebar.
Create a free account, or sign in with your MoltSets API key.
Open a profile. The panel picks it up from the page address.
Click "Get full profile", "Get email only" or "Get mobile". Results appear in seconds.
Add the contact to a list, download it, or send it to your CRM or workflow.

The sidebar stays open as you move between profiles, so you can build a list as you prospect. WHAT YOU GET Business email with a risk grade A: validated deliverable B: known engagement C: catch-all domain, deliverability unknown D: do not send F: unverified Full business profile Name, job title, seniority, function, location and time in role, plus company name, website, company page, industry, employee count and revenue range. The business email is included in the same lookup. Carrier-verified mobile number Available on paid plans with a phone token subscription. One token is used per number found, and lookups that find nothing are free. Personal email fallback If there's no business email and your plan includes personal emails, you'll see the personal addresses on file instead. LEAD LISTS AND CSV EXPORT • Create lists by campaign, territory, target account or hiring role • Add contacts from their profile, or select a batch and add them all at once • Search, rename or delete lists at any time (deleting a list never deletes its contacts) • Download a list or a selection as a CSV that opens cleanly in Excel or Google Sheets • Send a whole list to your CRM or workflow, with a progress bar and the option to stop • The Enriched profiles view shows everyone you've looked up, searchable by name, company or email SEND CONTACTS TO YOUR CRM AND WORKFLOWS Connect your tools on the Integrations page and send contacts without exporting a file. • HubSpot: create or update contacts, linked to their company. Send one, a selection or a whole list. • Salesforce: send as a Lead, or as a Contact linked to an Account. There's no token to create; it uses the Salesforce login already in your browser. • Attio: create a person record linked to their company, with a note holding industry, revenue range and email grades. Only empty fields are filled, so your team's edits are kept. • Webhooks: paste one URL to send contacts to Clay, Zapier, Make, n8n or any endpoint that accepts JSON. Every contact arrives in the same flat format, so your field mapping never breaks, and you can send a test contact first. Existing records are matched by email and company domain to avoid duplicates. Each profile shows when it was sent and flags it if the data has changed since. Emails graded D are never sent. PRICING • Free: 1,000 lookups to start • Paid: from $27/month, with no per-lookup credits and fair use limits sized to each plan • Mobile numbers: phone tokens, a monthly add-on on paid plans • Lists, CSV export and integrations are included on every plan • Nothing is looked up until you click, and your remaining usage is always visible in the panel See plans at moltsets.com/pricing PRIVACY AND PERMISSIONS The extension reads only the address of your active tab. It doesn't read page content or add anything to the pages you visit, and nothing is sent to MoltSets until you click a lookup. Your API key, results, lists, CRM tokens and webhook URLs stay in your browser and aren't synced to other devices. Keys, tokens and webhook URLs are encrypted with a passphrase you choose, and CRM tokens and webhook URLs are never sent to MoltSets. The extension contains no analytics or advertising code. Permissions: • Storage: keeps your key, results and lists on your device • linkedin.com: reads the address of your active tab only • api.moltsets.com: runs the lookups you ask for • Optional, requested only when you connect them: api.hubapi.com for HubSpot, api.attio.com for Attio, your webhook's site, and cookies plus salesforce.com and force.com for Salesforce. Only the Salesforce session cookie is read, at the moment you send, and it's never stored or sent to MoltSets. RESPONSIBLE USE 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. ALSO AVAILABLE The same data is available through the MoltSets API and MCP server, for enriching whole lists, searching for people and companies, and connecting AI assistants.
