The Apollo.io Chrome extension ("Apollo.io: Free B2B Phone Number & Email Finder" in the Chrome Web Store, about 1,000,000 users, last updated 15 October 2026) shows Apollo's data for the person whose LinkedIn profile you have open, and lets you save that person with their email, or with email and phone, into Apollo. From the same panel you can add them to a list or sequence and email them. It also works inside Gmail, Google Calendar, Salesforce, HubSpot and on company websites. Saving a contact spends Apollo credits, so the extension is as large as your Apollo plan's allowance.
What it does on a LinkedIn profile
According to Apollo's help article on prospecting with the extension (updated 12 May 2026), you open a LinkedIn profile and click the extension, then choose one of two actions:
- Save contact or Access email: saves the person to Apollo and reveals their email.
- Access email & phone: saves the person and reveals both email and phone number.
Once saved, the person can be added to a list or a sequence, emailed directly, or used as a starting point to view colleagues and similar profiles. The help article does not say whether the same actions are available on LinkedIn search result pages, Sales Navigator or company pages, so test those in your own account.
Apollo also warns that the extension does not remove EU- or UK-based contacts, and asks users to check a prospect's location on LinkedIn and meet GDPR requirements before adding them to outreach.
What it costs
The extension is free to install; the contacts are not. Apollo's help article states that saving contacts costs credits, and the credits come from your Apollo plan. Third-party trackers list Apollo's Free plan with 900 credits a year, Basic at $49 a user a month billed yearly with 30,000 credits a year, and Professional at $79 with 48,000 (Zeliq, 27 July 2026; Costbench, 26 July 2026). Apollo keeps emails, phone numbers and exports on separate limits inside its credit system, and unused credits do not roll over. Before you plan a month of prospecting through the extension, check how many credits a phone reveal costs in your account. Full figures are on our Apollo pricing page.
Where it stops being the right tool
- Volume. The extension works profile by profile. Saving a few hundred people from a LinkedIn or Sales Navigator search one at a time is slow, and each save draws on the same credit allowance.
- Getting data out. Saved contacts live in Apollo. To use them elsewhere you export from Apollo, within your plan's export limits. Our guide on exporting an Apollo search to Excel covers that route.
- Sharing a seat. Credits belong to the plan, so heavy extension use by one rep reduces what is left for the team.
For occasional lookups while you browse LinkedIn or read email, none of this matters, and the extension is a convenient way to use an Apollo plan you already pay for.
If you need whole lists instead of single profiles
Two jobs come up often, and both have a different tool:
- Export an Apollo search as a file. The Apollo scraper exports a people or company search from Apollo to CSV, with emails and phones. The Apollo scraper tutorial walks through it step by step.
- Turn a LinkedIn or Sales Navigator search into a list with contacts. Scrupp exports the whole search, past the 2,500 results Sales Navigator displays, then finds emails and phones for each person. A lead costs 1 credit, a found email 1 more and a found phone 2 more, with 100 free credits a month.
