Best Chrome extensions for LinkedIn

Apollo.io is the top pick for finding contact emails and phone numbers on LinkedIn profiles, while Grammarly is best if you mainly want cleaner messages and posts. The right choice depends on whether you are writing or prospecting.

Apollo.io adds a panel to LinkedIn profiles that surfaces available email addresses and phone numbers, with a limited number of free lookups per month before requiring a paid plan.

Apollo.io is a widely used sales tool that reads profile data you are viewing rather than automating actions on your account, which is lower risk than extensions that send bulk connection requests.

Extensions that automate mass connection requests, bulk messaging or large-scale data scraping violate LinkedIn's terms and can trigger account restrictions. Extensions that only look up individual profiles or check your writing carry far less risk.

Apollo.io's free plan includes a limited number of email and phone lookups per month, which covers occasional use. Higher-volume outreach requires a paid plan.

Most LinkedIn extensions from the Chrome Web Store, including Grammarly and Apollo.io, also install in Chromium-based browsers such as Microsoft Edge and Brave.

LinkedIn allows extensions that assist an individual user, such as grammar checkers, but restricts automated scraping or bulk actions under its user agreement. Read an extension's description carefully before installing it.

The free plan limits how many contact lookups and email credits you get per month, while paid plans raise those limits and add CRM syncing features. Check Apollo.io's current pricing page for exact limits.

Yes. Recruiters commonly use Apollo.io to find candidate contact details and Grammarly to polish outreach messages, though the same terms-of-service caution against bulk automation still applies.
