Clearbit Connect Alternative

The Clearbit Connect Replacement — Built for Outlook, Not Chrome

Clearbit Connect is gone. ListPlus picks up where it left off — inside Microsoft Outlook, where your inbox actually is. Verified emails, company enrichment, LinkedIn profiles. One click, no browser extension, no Chrome dependency.

Why Chrome Extensions Are Dying Anyway

Connect Was Never Going to Survive the Browser Treadmill

Even before HubSpot pulled the plug, the whole Chrome extension model was running out of road. Here's why the Outlook-native approach is the sensible move, not a compromise.

Manifest v3
Browsers keep tightening the leash

Every browser update narrows what extensions can do. API access, background workers, content scripts — all more restricted with each release. Extensions age fast, and maintaining them is a treadmill.

Wrong tab
Your email doesn't live in Chrome

Chrome extensions only work when you have Gmail open in a browser tab. If your team is on Outlook Desktop, Outlook for Mac or Outlook on the Web inside the Office app, a Chrome extension is useless.

IT friction
Every extension is an IT ticket

Corporate IT locks down browser extensions for good security reasons. Getting a new extension approved often takes longer than getting an Office Add-in deployed from the Microsoft Store.

One vendor
Connect was one provider, one database

Clearbit Connect was wired into a single proprietary data source. If that source didn't have the sender, you got nothing. Modern enrichment has to cascade across multiple providers — a single-source extension can't compete.

The Replacement

Everything Connect Did — Inside Outlook

ListPlus delivers the same daily moment Clearbit Connect used to: you open a cold email, a sidebar tells you who this person is, and you decide whether to reply. Here's how it does it.

Detect
Automatic Sender Detection on Every Email

Open any email in Outlook and ListPlus instantly identifies the sender, recipients and everyone who replied earlier in the thread. Calendar events work the same way — every attendee gets a contact card.

  • From, To, CC and full thread participants identified automatically
  • Calendar attendees ready to enrich the same way
  • Personal domains (gmail.com, outlook.com) filtered out of company lookups
  • The content of your email is never read, stored or sent anywhere
ListPlus Outlook Add-in sidebar identifying every sender, recipient and CC participant from the open email thread
Enrich
Verified Email + Company + LinkedIn in One Click

Clearbit Connect gave you a verified email and a quick company card. ListPlus does that and keeps going — company intelligence, full LinkedIn profile, phone numbers, decision-maker signals. All from the same sidebar, all without leaving Outlook.

  • Verified emails from a multi-provider waterfall
  • Company intelligence: industry, size, revenue range, tech stack
  • Full LinkedIn profile with headline, experience and education
  • Phone numbers and decision-maker signals on every contact
Waterfall enrichment providers selectable per contact in the ListPlus Outlook sidebar
Waterfall
Multiple Providers, Not a Single Database

Clearbit Connect ran on one proprietary source. ListPlus cascades through multiple B2B data providers — FullEnrich, Prospeo, CompanyEnrich, HarvestAPI, Enrich.so, Serper, MillionVerifier — until verified data appears. If the first misses, the next tries.

  • Automatic provider waterfall per contact
  • Per-action control — fetch only what you need
  • Verified results or nothing — no empty-lookup charges
  • Quality checks before data reaches your CRM

Export
From Inbox to Pipeline in One Click

Add the enriched contact to a ListPlus list, send it to Power Automate, Zapier or Make, or sync it to HubSpot, Salesforce or Pipedrive via the ListPlus web app. No copy-paste, no CSV exports.

  • Add to List — push contacts into any ListPlus list
  • Send to Webhook — Power Automate, Zapier, Make
  • CRM sync via the web app — HubSpot, Salesforce, Pipedrive
  • Cross-device sync — login once, token follows you everywhere

FAQ

Frequently Asked Questions

Can I still use Clearbit Connect?
No. Clearbit Connect was discontinued after HubSpot acquired Clearbit and rebranded it as Breeze Intelligence. The Chrome extension no longer works, and HubSpot has not released a direct replacement. ListPlus for Outlook is the direct alternative — same daily moment, different client, multi-provider data.
Does ListPlus work with Gmail or only Outlook?
The ListPlus Add-in is built for Microsoft Outlook — Desktop (Windows), Outlook for Mac and Outlook on the Web. If your team lives in Gmail, the ListPlus web app and Chrome extension cover that workflow separately. If your team is on Outlook, the Outlook Add-in is the native home.
How is this different from HubSpot Breeze Intelligence?
HubSpot Breeze Intelligence is bundled into HubSpot at enterprise pricing tiers and only accessible if you're already a HubSpot customer. ListPlus is a standalone Outlook Add-in that works whether or not you have a CRM, is hosted in Europe under GDPR, and cascades through multiple data providers instead of relying on one proprietary database.
Is there a free plan?
Yes. You can install ListPlus for Outlook from the Microsoft Store for free and sign up directly from the sidebar. The free plan includes everything you need to qualify your first contacts — no credit card required.
Is my email data safe?
ListPlus only looks at the participant list of the email you currently have open — From, To, CC, BCC and earlier replies in the thread. The body of your email is never read, stored or sent anywhere. Authentication runs over HTTPS only, and ListPlus is operated by Airrange GmbH in Munich on EU infrastructure under a GDPR-compliant Data Processing Agreement.
