Clearbit Connect Alternative

The Clearbit Connect Replacement — Built for Outlook, Not Chrome

Clearbit Connect is gone. ListPlus picks up the same daily moment — inside Microsoft Outlook, where your inbox actually is. Company data, LinkedIn profiles, emails and phone numbers. One click, no browser extension, no Chrome dependency.

Why Chrome Extensions Are a Fragile Home

Connect Was Never Going to Survive the Browser Treadmill

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

Browser LimitsManifest v3

Browsers keep tightening the leash

Browser updates keep narrowing 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 ClientWrong 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 for Windows, Outlook for Mac or Outlook on the web, a Chrome extension is useless.

IT BlockersIT friction

Every extension is an IT ticket

Corporate IT locks down browser extensions for good security reasons. Getting a new extension approved can take longer than deploying an Office Add-in from Microsoft AppSource.

Single SourceOne 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 work across multiple providers — a single-source extension can't compete.

The Bottom Line

Chrome extensions were always a fragile home for a business-critical workflow.

Your daily sender-lookup moment belongs inside Outlook — with multiple data providers behind it.

The Replacement

What 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

Sender and Recipients on Every Email

Open any email in Outlook and ListPlus shows the sender and recipients from the message header — for read, compose and calendar items. Meeting attendees get a contact card the same way.

  • Sender and recipients shown for read and compose items
  • Calendar attendees ready to enrich the same way
  • Works with the names and addresses Outlook already shows
  • The add-in does not read the message body

Enrich

Company, LinkedIn and Contact Details in One Click

Clearbit Connect gave you an email and a quick company card. ListPlus does that and keeps going — company data, LinkedIn profile, email and phone numbers. All from the same sidebar, all without leaving Outlook. You choose per contact what to fetch.

  • Company Lookup — industry, size, revenue range, location, website (0.25 credits)
  • Find LinkedIn Profile (0.5 credits)
  • Contact Profile Lite — email and phone via a single provider (2 credits)
  • Contact Profile Waterfall — email and phone via a 20-source waterfall (4 credits)

Waterfall

Multiple Providers, Not a Single Database

Clearbit Connect ran on one proprietary source. ListPlus works with multiple B2B data providers — FullEnrich, Prospeo, CompanyEnrich, HarvestAPI, Enrich.so, Serper, MillionVerifier — and the Contact Profile Waterfall cascades through 20+ sources. If the first misses, the next tries.

  • Multiple providers, one of them a 20-source waterfall
  • Per-action control — fetch only what you need
  • E-mail and phone lookups: credits only when found
  • Quality checks in the web app before data reaches your CRM

Export

From Inbox to Pipeline

Every enrichment writes the contact to your Outlook Contacts list in ListPlus. Add it to another list, send it to Power Automate, Zapier or Make via webhook, or sync it to HubSpot, Salesforce or Pipedrive from the ListPlus web app. No copy-paste.

  • Outlook Contacts list — created and updated automatically
  • Add to List — push contacts into any ListPlus list
  • Send to Webhook — Power Automate, Zapier, Make or any URL
  • CRM sync via the web app — HubSpot, Salesforce, Pipedrive (Premium)

FAQ

Frequently Asked Questions

Can I still use Clearbit Connect?

No. Clearbit Connect was discontinued after HubSpot acquired Clearbit in 2023 and folded it into Breeze Intelligence. The Chrome extension no longer works. ListPlus for Outlook is an alternative — same daily moment, different client, multiple data providers.

Does ListPlus work with Gmail or only Outlook?

The ListPlus Add-in is built for Microsoft Outlook — Outlook for Windows, Outlook for Mac and Outlook on the web. If your team lives in Gmail, the ListPlus web app covers the lookup workflow: paste a name, company or LinkedIn URL and enrich from there. If your team is on Outlook, the add-in is the native home.

How is this different from HubSpot Breeze Intelligence?

HubSpot Breeze Intelligence is part of HubSpot and only accessible if you're a HubSpot customer. ListPlus is a standalone Outlook Add-in that works whether or not you have a CRM, is hosted in Frankfurt, and works with multiple data providers instead of relying on one proprietary database.

Is there a free plan?

Yes. You can install ListPlus for Outlook from Microsoft AppSource for free and sign up directly from the sidebar. The free plan comes with 25 credits to enrich your first contacts — no credit card required.

Is my email data safe?

ListPlus only works with the participants Outlook already shows in the message header or the meeting — names and email addresses. The add-in does not read the message body. Enrichment providers receive only the identifier being enriched (an email address or domain). ListPlus is operated by Airrange GmbH in Munich on EU infrastructure in Frankfurt; a Data Processing Agreement is available on request for every plan.
