Qualify Every Lead Before You Reply — Right Inside Outlook
ListPlus is an Outlook Add-in — installed from the Microsoft Store — that shows you job title, decision-maker status, company size, industry, revenue and the full LinkedIn profile for every email sender. Without leaving your inbox.

Every Unknown Sender Is a 5-Minute Research Tax
Your SDR gets 50 emails a day. For every unfamiliar sender, they open LinkedIn, Google the company, check the website. 3–5 minutes per lead — before they've even decided whether to reply. And since Clearbit became HubSpot Breeze, there hasn't been a single dedicated enrichment tool for Outlook. Until now.
LinkedIn, company website, Google search — manual qualification eats hours every week before you've written a single reply.
SDRs, recruiters and AEs receive 50–200 emails daily. Most senders are strangers. Most need to be qualified before you waste a reply.
Lusha, Apollo and ZoomInfo all run on a single proprietary database. When their database misses, you miss. No fallback, no second chance.
Since HubSpot acquired Clearbit in 2023, there has been no dedicated Outlook enrichment add-in. Browser extensions overlay LinkedIn — none live where the email actually arrives.
Know Everyone in the Room
Open any email in Outlook. Click ListPlus. Everyone who's part of the conversation — sender, recipients, CC, people who replied earlier in the thread — appears in the sidebar with their full profile: job title, decision-maker status, company, LinkedIn, phone and more. No tab-switching. No manual research. No guessing who's the decision-maker.
ListPlus identifies everyone who's part of the message you're looking at — sender, recipients, CC, BCC and people who replied earlier in the thread. It only looks at the participant list. The body of your email is never read, stored or sent anywhere. Calendar events work the same way: every attendee gets a contact card, ready to enrich.
- Automatic identification of all email and calendar participants
- Covers earlier replies in the thread — not just the open message
- Personal domains (gmail.com, outlook.com) filtered out of company lookups
- Compose mode: recipients enriched live as you write

ListPlus shows you the full company profile the moment you open an email. Industry, size, revenue range, tech stack, founded year, LinkedIn company page. Everything you need to decide: is this lead in my ICP — or a polite no?
- Industry, company type and decision-maker signals
- Employee count, revenue range, founded year
- Tech stack, website, LinkedIn company page, phone
- Decision-maker status surfaced on every contact card

See the full LinkedIn profile of any email sender right inside Outlook — headline, work experience, education, connections, followers. Everything you'd get from Sales Navigator, minus the tab-switching.
- Full profile headline and current position
- Complete work history with dates
- Education details — university, degree, field
- Connection and follower counts plus direct profile link

Most enrichment tools are all-or-nothing. ListPlus lets you choose what to fetch for each contact: just the company, just the LinkedIn profile, or the full waterfall for a high-value prospect. Granular control, no wasted lookups. Waterfall enrichment cascades through 15+ providers — Enrich.so, HarvestAPI, FullEnrich, Prospeo, CompanyEnrich, Serper, Crunchbase, MillionVerifier — until verified data appears.
- Company Lookup — industry, size, revenue, HQ
- LinkedIn Profile — full profile, experience, education
- Contact Profile Lite — verified email and phone via Prospeo
- Contact Profile Waterfall — multi-provider fallback for max coverage
- Find LinkedIn URL · Crunchbase · Verify Email — pick exactly what you need

Every enriched contact lands automatically in an Outlook Contacts list inside the ListPlus web app. From there, sync to HubSpot, Salesforce or Pipedrive — or send straight to Power Automate, Zapier or Make via webhook directly from the sidebar.
- Add to List — push contacts into any ListPlus list
- Send to Webhook — Power Automate, Zapier, Make from the sidebar
- CRM sync via the ListPlus web app — HubSpot, Salesforce, Pipedrive
- Cross-device sync — login once, token roams to Web, Windows, Mac

Manual Qualification vs. ListPlus
The Clearbit Alternative for Outlook Users
When HubSpot acquired Clearbit in late 2023 and rebranded it as Breeze Intelligence, thousands of sales teams lost their favorite enrichment tool for Outlook. ListPlus fills that gap — and goes further.
Lives Inside Outlook
Unlike Clearbit, ListPlus is a Microsoft Office Add-in — not a browser extension. It lives where your email actually arrives: Outlook Desktop, Outlook for Mac and Outlook on the Web. One install, three platforms, zero browser extensions to manage.
Granular, Per-Field Enrichment
Unlike Lusha and Apollo, ListPlus gives you per-field control. Fetch just the company, just the LinkedIn profile, or the full waterfall — your choice, contact by contact. You only pay for the data you actually need, never for an all-or-nothing bundle.
Waterfall + EU-Native
Unlike single-provider tools, ListPlus cascades through 15+ data sources in one click for maximum coverage. And unlike US-only competitors, ListPlus is built by Airrange GmbH in Munich, hosted on EU infrastructure, and fully GDPR-compliant.
