Apollo.io offers prospecting tools and a free Chrome extension. Below are the key features, the current limits, plus a few alternatives worth a look.
What is the Apollo.io Chrome Extension?
The Apollo.io Chrome Extension allows you to use Apollo data and actions in LinkedIn, Gmail, Salesforce or HubSpot, or on company websites. With a few clicks you can find prospects’ professional contact information right inside those tools, with no tab switching.
Apollo.io Chrome Extension Overview
One feature that makes a lead generation or sales tool service stand out is its integration with other platforms and tools. This is why Apollo.io’s Chrome extension is one of the platform’s most important tools. It integrates Apollo.io’s prospecting and sales functionality into daily applications and websites used by salespeople: LinkedIn, Gmail, Salesforce, HubSpot, plus company websites.
Apollo.io’s own product page lists more than 240 million contacts and over 30 million companies in its database as of August 2026, up from the figures the company cited a couple of years ago. With the Chrome Extension you can access verified contact information straight from LinkedIn profiles and company pages. That includes emails and phone numbers when available. It lets users add prospects to Apollo.io lists and sequences. It also tracks emails and sets follow-up reminders, plus it drops email templates into Gmail. It provides insights and one-click actions within Salesforce and HubSpot too, cutting down manual steps in the prospecting workflow.
This centralizes sales activities and data across multiple platforms, saving time. One drawback to weigh before adopting it: each connected platform needs its own setup and configuration, which can take a while to get fully working.
Apollo.io Extension Use Cases
Salespeople use the Apollo.io Chrome extension for several purposes. Apollo lists Google Calendar among the tools it surfaces context in. Below, we cover the extension’s core use cases.
The Apollo.io Chrome Extension integrates directly with LinkedIn. Once installed on your Chrome account, you can pull verified contact information from LinkedIn profiles and company pages. That includes direct mobile numbers and email addresses where available. This cuts the time needed to gather accurate lead data.
Do not use tools that scrape or automate LinkedIn. LinkedIn bans unauthorized bots and scrapers, along with extensions that automate the platform.
You can also add prospects to Apollo.io lists and sequences directly from LinkedIn using the extension. Track job changes and reach contacts by email or phone without leaving the platform.
Keeping prospecting activity inside the LinkedIn interface saves time for sales professionals who spend most of their day there.
Gmail
With the Apollo.io Chrome Extension, Gmail becomes a sales outreach and engagement tool in its own right. Once installed, the extension adds features that speed up email prospecting.
In Gmail the extension tracks emails and sets follow-ups. It also drops in templates and logs activity automatically.
Google Calendar
Once connected to Google Calendar, the extension brings Apollo.io’s prospecting data into your calendar view. With this integration, you can pull up information about a prospect before a meeting instead of digging for it separately.
This is useful for sales professionals who manage a packed meeting schedule. Having prospect data on hand ahead of a call makes it easier to prepare and personalize the conversation.
HubSpot
With the extension installed, you can view Apollo.io’s contact profiles directly inside HubSpot. It also lets you add HubSpot contacts straight to Apollo.io lists and sequences, so you can start a targeted outreach campaign without exporting anything. The Chrome Extension connects Apollo.io and HubSpot data so sales teams can work from one screen instead of two.
Salesforce
The Apollo.io Chrome extension also integrates directly with Salesforce, letting users view Apollo.io’s contact profiles inside Salesforce itself. This keeps prospect information current without a separate lookup step.
You can add contacts from Salesforce to Apollo.io lists and sequences, which cuts a few steps out of launching a targeted outreach campaign. The extension handles task creation and call logging, then syncs activity with Salesforce automatically. You can also configure calling in Apollo.io and sync outcomes back to Salesforce. Apollo’s own integration page also lists Outreach and Salesloft as sequence destinations for contacts captured through the extension, so teams running those tools instead of Salesforce or HubSpot get the same shortcut.
General Web Browsing
During general web browsing, the extension adds a layer of prospecting data. By default, it surfaces Apollo.io’s company insights on most company websites, so users can look up potential prospects and clients without leaving the page. This saves time and keeps sales teams working from current information instead of digging for it. The extension shows Apollo.io company info on many corporate sites and lets you prospect straight from those pages.
