What is Lusha? Revealing emails and direct dials from a 515-million-contact base
Lusha (Lusha Systems) is a database of business contacts and companies, sold by credits. You filter it by job title, company, country or buying signal, then reveal the details you need. Lusha claims 515M+ contacts, 29M+ companies, 165 million verified emails and 117 million direct dials; by country, 132 million contacts in the United States (87.8 million in its FAQ), 103.1 million in Europe, 16.1 million in France (figures updated on September 30, 2026).
Workspace, the web app
Search and filters cost nothing; revealing does. An email costs 1 credit, a phone number 5, both up to 6; a contact already revealed is free to view again. Lists can be enriched in bulk from a CSV file.
The browser extension
A side panel for Chrome and Edge that looks up whoever is on screen, whether you are on LinkedIn, in a CRM or on a company website.
API and MCP access
For developers and RevOps: enrichment, prospecting searches, lookalikes and signals by API, plus an MCP server that lets AI assistants such as Claude and ChatGPT query the base.
Signals and lookalikes
26 buying signals refreshed weekly, lookalike contacts and companies, website visitor identification and meeting recording. Signals, website visits and recorded meetings spend credits (1, 2 and 8).
The “Lusha notice” email: why people who never signed up hear from Lusha
Most searches for “Lusha notice”, “Lusha Systems” or “Lusha company” come from people who are not customers. They received an email from Lusha titled “Personal Information Notice”: Lusha sends it to people it adds to its database, to tell them it holds their business details (name, company, job title, email, phone number and country, and more) and sells access to them.
What the notice lets you do
If it is the first time Lusha notifies you, you have 14 days from the email to refuse being added. After that, you can opt out at any time through the removal form or by email: your record is removed, put on a suppression list so it does not come back, and the customers who had obtained it are told. The current version of the notice is dated May 2026; it also exists in French, Italian, German, Spanish and Dutch.
Where Lusha says the data comes from
The notice lists several sources: its community (users who connect their work mailbox and share the headers and signatures of their emails), companies of its group, data brokers and public APIs, an algorithm that guesses addresses from a company’s email format, and the LinkedIn profiles its customers open while the extension is running.
Those brokers appear in the notice itself, as “trusted data brokers”, even though Lusha’s FAQ states that it “does not buy from data brokers”.
Lusha Chrome extension: contact details on LinkedIn, Sales Navigator, your CRM and Gmail
Click the Lusha icon and a side panel opens next to the page, showing what the database holds on that person or company. The same extension runs in Edge, installed from Microsoft’s add-ons store rather than the Chrome Web Store.
Where it works
It opens on LinkedIn profiles, search results and company pages, in Sales Navigator, in Salesforce, HubSpot and Gmail, and on company websites. A setting called “Lusha Everywhere” extends it to other B2B sites, and LinkedIn Recruiter works once Lusha’s support has approved it for your account.
What you can do from the panel
Reveals draw on the account’s shared credits at the usual rate: 1 for an email, 5 for a phone number. A contact can then be saved to a Workspace table, sent to Salesforce, HubSpot or Pipedrive, or added to an Engage sequence, up to 150 at once. When Lusha has nothing on someone yet, a wishlist keeps them and alerts you if details appear.
Sales Navigator searches
Selected leads go into a Lusha table in batches of 25, so a long search takes several rounds. There is no CSV export from the extension itself: the table is exported from Workspace, at 1 credit per 25 rows. In the same Sales Navigator search, Emelia’s Chrome extension adds an Export with Emelia button that passes the whole search to Emelia, which extracts the leads; their emails can then be found at 1 credit per email found (how it works).
Your LinkedIn account, and where the data comes from
Lusha says the extension performs “no automated activity on your account”: it reads the profile you have open and matches it against the database, without sending invitations or messages. Its pages disagree on what it takes from LinkedIn: the extension page says the data does not come from LinkedIn’s pages directly, while the notice sent to people in the database counts the profiles customers view with the extension among its sources. On the Chrome Web Store, it has 400,000 users and a 4.6 rating (1.9K ratings); the latest version dates from October 7, 2026.

Lusha HubSpot integration: what lands in the CRM, and how duplicates are avoided
Lusha’s pricing table includes CRM integrations on every plan, Free among them, and HubSpot is one of the native ones. Once it is connected from Lusha’s integration settings, the contacts and companies you reveal can be pushed into HubSpot with their fields mapped: email, phones, job title and seniority for a person; name, domain, address, headcount and LinkedIn page for a company. A mapping can be changed, given a fixed value, or applied only when an email or phone number is enriched.
An export sends up to 100 contacts in real time; larger selections run in the background, up to 1,000 per job, which is HubSpot’s own ceiling, and whatever is left is marked “Not exported” for the next run. Company records only go in real time, each user runs one CRM export at a time, and an export from Workspace costs 1 credit.
Before creating anything, Lusha looks for the record in HubSpot: a contact is matched on email, or on first and last name with the company name or domain; a company on its name or domain. An admin can also stop exports from creating new records, so that Lusha only updates the ones already there.
Lusha also shows up inside HubSpot itself. With the extension’s “Lusha Everywhere” setting on, a Lusha widget appears in the CRM; and a separate Marketplace app, Lusha B2B Intelligence, puts a signals card (job changes, promotions, hiring surges, headcount growth) on every contact record. Each rep connects their own Lusha licence to that app, and signals are paid in credits.
Lusha API documentation: endpoints, rate limits by plan, and the MCP server
The documentation sits at docs.lusha.com, with a developer reference for each endpoint: people and companies (enrichment, in bulk up to 100 records per request), prospecting searches by job title, seniority, location or industry, lookalikes, signals and a signal score, and transcripts of calls recorded by Lusha. Inside the app, an API Hub holds the keys and a playground for test requests.
According to that documentation and the pricing table, every user gets a key on every plan, Free included; the help centre’s “Introduction to Lusha” page still says “Scale plan only”. Limits rise with the plan: 40 requests a minute and 100 a day on Free and Starter, 1,500 a day on Pro, 18,000 on Premium and 50,000 on Scale.
Calls spend the account’s shared pool of credits: 1 per email, 5 per phone number, 1 per company, plus 1 per request for each block of up to 25 results, which makes 7 for an email and a phone together. The help centre adds that a request returning nothing still costs a credit, whereas Lusha’s FAQ says an unmatched lookup is free. Admins and managers can give each key they create its own monthly credit cap.
The MCP server connects AI tools such as Claude, ChatGPT, Cursor or Gemini CLI through OAuth rather than an API key, on every plan and against the same credits; it looks people and companies up, but cannot send messages or add anyone to a sequence. Lusha’s API notice also rules out using its data to train AI models, save for exceptions set out in its terms.
GDPR at Lusha: legitimate interest, no consent, compliance left to the sender
Lusha processes the people in its database under legitimate interest, not consent: nobody agreed to be in it. Its help centre is explicit that it collects no consent for prospecting, and that checking whether an email or a call is lawful is up to the customer who sends it. According to its help centre and pricing page, numbers on Do Not Call lists (the UK’s TPS and CTPS, US registries) are masked on the Scale plan only; its FAQ says every phone record carries a Do Not Call flag.
On security, Lusha holds SOC 2 Type II, ISO 27001, ISO 27701, ISO 27017, ISO 31700 and ISO 42001 certifications. Legitimate interest, however, did not convince Italy’s data protection authority, the Garante. It opened an investigation into Lusha on April 8, 2025 and, in a decision dated July 14, 2026, refused that basis, imposed a 2 million euro fine on Lusha Systems Inc. and ordered it to stop processing the data of people in Italy collected without an adequate legal basis, and to erase it. That decision is being contested before the Rome court; following a court order of September 8, 2026, the Garante has temporarily taken it off its website.
Engage: email sequences sent from each user’s Gmail or Outlook
Lusha added a sequencer, Engage, to every plan at no extra cost, the free one included: steps with delays, AI-written emails (OpenAI), one-off emails, open tracking, and a stop when someone replies or an email bounces. Emails leave from the Gmail or Outlook mailbox of each user; there is no SMTP option.
The limits are those of a personal mailbox: 1,000 emails a day per user at most, 50 recommended (20 to 30 on a new domain), and 10 active sequences per user. We found nothing on warm-up, inbox rotation or several sending mailboxes per user. That is why Engage is a way to follow up on contacts found in Lusha, not a cold email platform.
Lusha or Emelia: revealing contacts, or also writing to them and inviting them on LinkedIn
The two tools meet on one job: finding a contact’s email or phone number. Below, what each costs for the same monthly need (Lusha: the cheapest plan that gives the credits; Emelia: Start plus the monthly credit pack that covers it), then what only one of them does.

All amounts are in dollars: it is the only currency Lusha bills in, and Emelia’s price is the same figure in euros or dollars, so nothing is converted. Emelia’s credits given once at signup are not counted; a phone number costs 5 credits at Lusha and 50 at Emelia, which is why Lusha wins the phone line.
Ratings in brief: customers and the people in the database disagree

Logging in, the extension, HubSpot and the API: Lusha in practice
At auth.lusha.com/login, the “Login” link at the top of lusha.com. Signing up requires a work email: Gmail, Yahoo or generic addresses such as info@ are refused, and fraud checks suspend some new accounts at signup; an appeal is reviewed in 1 to 3 working days.
Lusha’s help centre lists Chrome and Edge: the Chrome version comes from the Chrome Web Store, the Edge one from Microsoft’s add-ons store.
Yes, through a native connection made under Settings, then Integrations, in Lusha; Salesforce, Pipedrive, Zoho, Microsoft Dynamics and Bullhorn connect the same way.
On docs.lusha.com. Your personal key is in the API Hub, in the left sidebar of the Lusha app.
There is a permanent free plan: 40 credits a month (40 emails or 8 phone numbers), one licence, no card. Paid plans start at $49.90 a month; the pricing page details them.
Emelia is a Lusha competitor. We have tried to stay fair: every figure about Lusha comes from its own website or public review sites.
