Lemlist Chrome Extension: Gmail, LinkedIn, and CRM Workflow

The Lemlist Chrome extension is useful when reps need to move contacts from LinkedIn or Gmail into Lemlist lists and campaigns, with selected CRM screens supporting the same workflow. It is not a low-risk shortcut around LinkedIn rules. Buyers should price enrichment credits, inspect browser permissions, test duplicate behavior, and test CRM behavior before broad use.

Lemlist Chrome extension: quick facts

The official Chrome Web Store listing uses extension ID khnbclggeggefodgimdekejhipkeobnc. During review it showed version 5.0.25, updated November 10, 2026, and 80,000 users. Marketplace verification is a distribution signal, not an independent security audit.

Installation links a browser session to Lemlist

Lemlist's installation guide requires Chrome and active Lemlist and LinkedIn sessions in the same browser profile. After installation, the user opens the sidebar in LinkedIn, confirms the detected accounts, and links them.

The extension relies on browser cookies to recognize the LinkedIn session. It works on LinkedIn and Sales Navigator, but Lemlist says it does not work in LinkedIn Recruiter or on LinkedIn event pages. Keep the extension in a dedicated work browser profile so personal sessions and unrelated customer accounts are not exposed to the same extension context.

The Web Store says the extension handles authentication information and website content. Inspection of the current package manifest found permissions for storage, tabs, cookies, web requests, and a side panel. Host permissions cover LinkedIn and Lemlist domains. Content scripts also run on Gmail, HubSpot, Pipedrive, and Salesforce domains.

Those declarations describe technical reach, not proof that every visible field is collected. They are still broad enough to require a security review, least-privilege browser policy, controlled rollout, and a documented removal process.

LinkedIn is the main capture surface

Lemlist's extension operating guide lets users add individual or bulk LinkedIn contacts to lists and campaigns, enrich contacts, call through Lemlist, review campaign status, start one-to-one sequences, and pause or remove contacts. Its product page covers profile capture, search-result capture, and Sales Navigator list capture.

The LinkedIn import guide documents up to 999 contacts per LinkedIn search import and up to 2,500 per Sales Navigator import. These are product limits, not permissions from LinkedIn.

Bulk capture is intentionally thin. It imports first name, last name, and LinkedIn URL by default. Additional contact and company fields require enrichment. One-by-one profile import can collect fuller profile information.

Lemlist can match records by email or LinkedIn member ID and update a matched profile rather than creating a deliberate duplicate. It can also skip contacts already in a selected campaign. Test these rules with name changes, shared domains, missing emails, and records already present through a CRM sync.

A campaign sourced through CRM import cannot also accept Chrome-extension imports. Decide which system owns campaign membership before reps start moving contacts.

Gmail and CRM surfaces have different entitlements

Inside Gmail, the extension can track messages sent outside Lemlist campaigns, insert saved templates, and provide writing tools. That helps a rep handle one-to-one work in context, but it should not be confused with a governed campaign sequence or complete CRM activity history.

HubSpot supports individual and list-view imports, enrichment, list or campaign handoff, and dialing. The quick extension push is different from Lemlist's separate saved-segment CRM import, which can support repeatable synchronization and automatic pauses. Pick one route for each use case and document its update behavior.

Salesforce has a similar in-CRM workflow, but Lemlist's help material says that surface requires Enterprise. The live pricing page lists CRM integrations across engagement plans while reserving the ability to work in Lemlist from the CRM for Enterprise.

Pipedrive support is narrower. Lemlist's Pipedrive guide describes a progressive beta that requires extension version 5.0.20 or later and the Work from CRM option. It does not work in Pipedrive's Leads inbox or on deal pages. Company-panel access is a separate beta.

A buyer should demonstrate the exact surface, plan, record type, and user role rather than accepting a generic CRM integration claim.

Enrichment credits determine the real cost

Lemlist's credit rules charge five credits when Email Finder and Verifier returns a deliverable or risky address. Verifying an existing email costs one credit. LinkedIn enrichment costs one credit. Phone Finder costs 20 credits when it finds a number.

The word successful changes by action. A risky email can be an accept-all, full-mailbox, or disposable result. Lemlist's status guide does not treat that as a no-bounce promise. Lemlist also says it does not verify that a found phone number is correct or in service before charging.

Credits are pooled across the team and attributed to the initiating user in reports. Plan credits reset monthly. Subscription add-on credits roll over while the add-on remains active, while one-off top-ups do not expire at the plan anniversary. When credits run out, enrichment pauses but campaigns continue sending.

The public site describes more than 25 providers overall, while the credit guide says the email waterfall checks up to ten providers. Do not assume every lookup queries every named source.

At review, Lemlist listed Email at €69 per month on monthly billing and Multichannel at €109 per user per month. Annual displays showed lower monthly equivalents. A 2,000-credit enrichment add-on displayed €20 per month on monthly billing. Current currency, taxes, user count, Enterprise access, and credit consumption all belong in the order-form comparison.

Export and CRM acceptance need a controlled test

Lemlist's CSV export guide supports full, filtered, or selected campaign exports. Documented fields include name, email, company, LinkedIn URL, phone, and populated custom variables.

CSV availability does not prove a clean system exit. Test whether exports preserve source, verification status, timestamps, consent or suppression fields, campaign membership, replies, and custom variables needed by the destination.

For CRM handoff, test one new contact, one update, one duplicate, one suppressed record, and one record without an email. Verify field mapping, overwrite precedence, campaign membership, pause-on-reply behavior, and rollback. Count an enriched contact only when it passes the buyer's acceptance rules and appears correctly in the system of record.

LinkedIn limits do not remove platform risk

Lemlist provides daily action settings, invitation ramp-up, plan detection, pending-invitation controls, recovery guidance, and a LinkedIn Health Score beta. Its ramp-up guide focuses on invitations. Other LinkedIn actions need separate limits, and manual actions still contribute to platform activity even when Lemlist cannot see them.

LinkedIn's automation policy says it does not permit browser extensions or third-party software that scrape, modify the site's appearance, or automate activity. It specifically identifies adding or downloading contacts and sending messages through unauthorized automation, with account restriction or shutdown as possible consequences.

No numeric delay, invitation ramp, health score, or daily limit converts an unauthorized workflow into an authorized one. Teams with a strict policy requirement should use the extension only for functions LinkedIn has approved in writing, or keep LinkedIn work manual.

Privacy terms need to match the extension scope

Lemlist's privacy policy, effective November 3, 2026, says Lemlist acts as processor for customer contact lists, campaigns, and messages while the customer remains controller. It states that platform databases are hosted in the European Union, while some subprocessors can process data elsewhere under approved transfer mechanisms.

The policy says customer lists, campaigns, and messages are retained during the subscription and then deleted under the data processing agreement or customer instructions. It also says customer message content is not used to train AI models.

Enrichment data has another boundary. Lemlist says professional contact details returned through enrichment may update its People Database, and database profiles can be selected or exported by customers. Ask which extension actions contribute data to that database, what source and correction fields are retained, and how deletion or objection requests flow through customer exports.

Run a bounded extension pilot

Use a dedicated browser profile, one Lemlist workspace, test CRM objects, and a small list of known contacts.

1. Record the installed extension ID, version, permissions, allowed domains, and browser policy.
2. Import individual LinkedIn profiles, a small search result, and a Sales Navigator list without paid enrichment.
3. Add enrichment and record credits charged for deliverable, risky, unknown, and failed results.
4. Push controlled records through HubSpot, Salesforce, or the eligible Pipedrive beta and inspect every field change.
5. Verify duplicate, suppression, campaign-source, pause, and removal behavior.
6. Export the records and confirm the required source, status, and custom fields survive.
7. Revoke CRM and Lemlist access, remove the extension, clear its site data, and verify that scheduled actions stop.

Pass only if permissions are approved, platform risk is accepted, charges match documented outcomes, duplicate controls work, CRM writes are reversible, and the exported data is complete.

Need an extension acceptance test before rollout?

We can build the isolated browser and CRM fixture, define accepted-record rules, and document every handoff. The passing workflow can then sit inside a client-owned outbound system with clear stop conditions.
