ZoomInfo: a B2B database sold on quote, its Chrome extension and API

The ZoomInfo Chrome extension on LinkedIn, Sales Navigator and company websites

The extension is one of the most searched parts of ZoomInfo. Open a LinkedIn profile, a Sales Navigator lead or a company website, click the “Z” tab (or press Cmd / Ctrl + J), and the matching record from ZoomInfo’s database opens in a side panel. The Chrome Web Store lists it as free for ZoomInfo customers: what it shows is drawn from your contract, where seeing an email or a phone number uses one of your monthly views and exporting the record costs 1 credit.

On the store it has 300,000 users and a rating of 1.6 out of 5 from 295 ratings (version 12.22.1, updated October 13, 2026). On September 11, 2026 the same listing showed 3.49 from 302 ratings: since the side-panel redesign of July 2026, reviewers describe missing features and sign-ins that fail.

On a profile, the panel shows the work email, direct dial and mobile number your plan covers, buying-intent signals, a fit score and an AI-drafted email, and sends the record in one click to Salesforce, HubSpot, Outreach or Salesloft. ZoomInfo’s help centre describes a single record at a time, or the contact list of one company; it describes no way to pull a whole Sales Navigator search out at once.

Emelia’s Chrome extension works on the same pages and goes further. On a LinkedIn profile, a floating Emelia button finds the person’s email and phone number, paid in credits only when found, and adds the person to an Emelia campaign, email, LinkedIn or multichannel. Inside a Sales Navigator search, its “Export with Emelia” button hands the whole search to Emelia, which extracts the leads, then lets you export them, find their emails with credits or drop them into a campaign (Emelia’s Chrome extension, Sales Navigator export guide).

What ZoomInfo does, and where its data comes from

ZoomInfo sells access to a database of business contacts and companies: you search and filter it for free, and pay to reveal and export records. It now presents itself as an “all-in-one AI GTM platform”, with buying intent, website-visitor identification, conversation intelligence and AI agents sold on top of the data.

Who uses it. ZoomInfo counts 35,000+ paying customers (companies with at least one paid subscription), 1,891 of them paying $100,000 a year or more as of June 30, 2026. It says 8 of the 10 largest companies in the world and more than 50% of the Fortune 500 use it, and describes its fit as sales, marketing and RevOps teams at companies of 100 employees and up.

Where the data comes from. ZoomInfo cites 1.5B+ data points processed a day and 300+ human researchers. A further source is its free tier: ZoomInfo Lite users can feed the database with the contacts of the mailbox they connect (whether that sharing is required is one of the points ZoomInfo’s pages disagree on, see below).

Security certifications. ZoomInfo lists ISO 27001, ISO 27701, SOC 2 Type II, ISO 27017 and ISO 42001 on its home page and in its comparison pages.

ZoomInfo Technologies: from DiscoverOrg in 2007 to the Nasdaq ticker GTM

Henry Schuck founded the company as DiscoverOrg in 2007; ZoomInfo’s business FAQ also names Kirk Brown as co-founder, while its About page and llms.txt list Henry Schuck alone. DiscoverOrg bought ZoomInfo in February 2019 and took its name, went public on the Nasdaq on June 4, 2020, and switched its ticker from ZI to GTM on May 13, 2025. Henry Schuck is still chief executive.

The listed company, ZoomInfo Technologies Inc., is based in Vancouver, Washington, with offices including Waltham, Bethesda, Boston, London, Ra’anana, Bangalore and Chennai. It had 3,180 employees at the end of 2025, 72% of them in North America and 3% in Europe.

ZoomInfo API, MCP and 189 integrations, from Salesforce to Smartlead

There are two ways to reach ZoomInfo’s data from code. Customers on contract use its enterprise B2B data API, capped at 25 requests per second per customer, or 30 and 35 with paid options. Anyone else can open a GTM.AI account: an API, an MCP server and a command line, with no contract and no seat.

GTM.AI gives 1,000 data credits and 1,000 AI credits once, without a card, then sells data credits from $0.45 down to $0.25 each depending on the quantity (the grid is on the ZoomInfo pricing page). The free tier allows 5 requests per second and 5 applications, and enriches up to 10 records per call; mobile numbers are kept for the Enterprise offer.

Through the MCP server an AI assistant can query ZoomInfo directly; ZoomInfo added native MCP connections with Outreach, Showpad, Superhuman and Salesforce Agentforce in 2026, and an AI action usually costs 5 to 15 AI credits. Existing customers cannot pay MCP calls from their monthly credits: they need bulk credits.

The integrations page listed 189 entries on October 16, 2026, where the home page says 120+. Native CRM sync covers Salesforce, HubSpot and Microsoft Dynamics 365; the list also has Zoho CRM, Pipedrive, SugarCRM and Bullhorn, sending tools such as Outreach, Salesloft, Gong Engage, Mixmax, lemlist, Instantly.ai and Smartlead.ai, Zapier, Make, n8n and Workato, Snowflake, Databricks and BigQuery, and AI tools (Claude, ChatGPT, Gemini, Microsoft Copilot and Cursor). Emelia is not on it: records exported to a CSV file from ZoomInfo can be imported into Emelia, which syncs with 1 CRM on Start and Grow and several on Scale.

ZoomInfo Copilot is now GTM Workspace

Searches for “ZoomInfo Copilot” land on a product that has been renamed. ZoomInfo launched GTM Workspace for salespeople in October 2025 and says ZoomInfo Copilot is no longer sold as a standalone product. Its pricing page, though, still shows two cards under the old name, Copilot Advanced and Copilot Enterprise, without prices.

What those two cards add to ZoomInfo Professional: on Copilot Advanced, buying-intent signals, website visitors, account fit scores, email export to Outreach or Salesloft and “workflows for automated outreach”; on Copilot Enterprise, real-time intent, custom integrations and a dedicated customer service manager. ZoomInfo tracks 4,500+ intent topics and 85M+ signals a week.

GTM Workspace drafts emails with AI, but its help centre has you send them one by one: the Gmail icon opens Gmail with the message pre-filled. Its Copilot page says sequencing lives in the same workspace; the help centre describes sequences in Engage, an add-on with no published price (one email provider per user, 500 emails a day), and ZoomInfo’s Engage page now redirects to its Salesloft partnership.

Two more AI layers sit alongside it: GTM Studio (launched May 2025) for marketing and RevOps, with enrichment across 25+ sources, and Agent Teams (October 2026), agents that research accounts and can send emails through Gmail or enrol contacts in Salesloft or Outreach sequences, paid in AI credits.

ZoomInfo Lite and Community Edition: free credits, and the mailbox question

ZoomInfo Lite is ZoomInfo’s free, permanent tier, without a card. It is open only to people who are neither customers nor former customers, and only with a work email address. ZoomInfo’s product pages present it as the former Community Edition; its blog and Lite FAQ treat Community Edition as a tier with more credits.

ZoomInfo’s help centre gives 10 free credits at sign-up; its blog speaks of 10 credits a month, or 25 with “Community Edition”. One credit reveals a contact’s work email and a direct or office line, not a mobile number, and unused credits do not roll over.

Lite also covers searching the database, company profiles, the ReachOut extension and the mobile app, AI-written emails, an integration with HubSpot (Salesforce too, according to a FAQ answer on the same page) and WebSights Lite, which names 10 website visitors a day.

On the mailbox, ZoomInfo’s documents point in two directions. The Lite terms, dated March 13, 2025, grant access in exchange for access to the mailbox you connect (contacts, signatures, headers, auto-replies), with a perpetual licence to sell that data to ZoomInfo’s customers. The Lite FAQ answers “No” to whether you must share your contacts, and presents sharing as the way to earn more credits. Check the terms in force on the day you sign up.

Getting your own details removed from ZoomInfo

If you found your own name in ZoomInfo, requests go through its Privacy Center, at privacy.zoominfo.com, which handles opt-outs and deletion. ZoomInfo says it emails professionals when their record is added.

An opt-out reaches customers too: ZoomInfo’s contract obliges them to check its suppression list at least once a month and to delete the records on it. Customers who buy European data through the Data Passport option can also hide the emails and phone numbers of EU records. On Trustpilot, some reviewers describe a personal mobile number listed as a business line and deletion requests left without an answer.

Exporting from ZoomInfo: 1 credit per record, and no bulk scraping

Searching is free; taking a record out is what you pay for. Each export to a CSV file or an integration costs 1 credit per record, contact or company, with the email and phone numbers your contract covers. A record already exported can be taken out again for free for 12 months, but per user for manual exports: when two colleagues export the same person, two credits go.

Credits follow two clocks. Monthly credits, given per user on some plans, reset on day 1 of each month at midnight Pacific time and never roll over; bulk credits, shared by the organisation, are lost when the contract ends.

Exported data stays under the contract. Shared logins are billed as extra seats until the end of the term, and handing records to an unauthorised third party carries liquidated damages of $2.00 per record and per recipient. ZoomInfo documents no tool to extract a LinkedIn search in bulk; Emelia extracts LinkedIn and Sales Navigator searches without limit on every plan, and charges only for the emails it then finds.

ZoomInfo or Emelia: a database on contract, or prospecting at public monthly prices

Both answer one need: the work email of the people you want to reach. ZoomInfo sells it as records from its database, mostly on a yearly quote; Emelia finds the email of leads you bring or extract from LinkedIn, then sends the campaign. The ZoomInfo app has no public price, so every price line below uses GTM.AI, the only one ZoomInfo publishes. On Emelia’s side, those lines count its monthly credit pack and nothing else: looking up emails and phone numbers requires no Emelia plan.

GTM.AI prices are in US dollars, the only currency it bills in; Emelia’s show in your currency, as it charges the same figure in euros or dollars. A GTM.AI credit buys a whole record (email, direct line, job title…; no mobile numbers outside the Enterprise offer); an Emelia credit is an email found and verified, nothing when none is found, and a phone number costs 50 credits, only when one is found. GTM.AI also takes 70% off a first purchase, for a limited time. More volumes on the pricing page.

ZoomInfo pricing in short: seats, credits and a contract you cannot cancel

ZoomInfo publishes no subscription price. The 6 cards on its pricing page (ZoomInfo Professional, Copilot Advanced, Copilot Enterprise, Marketing Demand, ABM Lite and ABM Enterprise) show no amount and lead to a sales call. Its pricing FAQ says ZoomInfo “uses a seat-based pricing model”, while the home page says it does not charge by fixed seat tiers; the quote depends on licences, the credits you use and the features you take.

Contracts run 1 to 3 years (53% of contract value is multi-year, per the annual report), billed in advance, and the licence terms say the agreement is not cancellable. Up to the version of March 6, 2024, those terms renewed the contract automatically unless notice was given 60 days before it ended, at 10% above the previous price; the current text leaves renewal to the order form. What goes into a quote, and the one public price, are on the ZoomInfo pricing page.

ZoomInfo reviews, alternatives and head-to-head comparisons

Ratings depend sharply on who is asked: 4.5 on G2, 1.8 on Trustpilot. What each audience praises and complains about is on the ZoomInfo reviews page. If you are replacing ZoomInfo, the ZoomInfo alternatives page sorts the options by what you used it for.
