Apollo's Chrome extension is the most complete prospecting tool in this list. Hover over any LinkedIn profile and pull email, phone, company data, and engagement history. Start a sequence without leaving LinkedIn. The free tier gives you 10,000 email credits per month, which is more than most reps use.

Frequently Asked Questions
Do Chrome extensions slow down my browser?
Most sales extensions have minimal impact. Apollo, Lusha, and Hunter only activate when you click them or visit specific sites. Grammarly runs in the background and can slow down text-heavy pages slightly. If you notice lag, disable extensions you aren't using daily. Five active extensions is a reasonable limit.
Are Chrome extensions safe for my company's data?
Reputable tools (Apollo, Lusha, Grammarly) follow standard security practices. But every extension you install can read data from web pages you visit. Check the permissions each extension requests before installing. Avoid extensions from unknown developers, and clear your extensions quarterly to remove anything you've stopped using.
Can I use Apollo and Lusha extensions at the same time?
Yes, but it's redundant for email lookups. Where it makes sense: use Apollo as your primary for LinkedIn prospecting and sequence creation, and keep Lusha installed for quick phone number lookups on profiles where Apollo doesn't have a direct dial. Two data sources are better than one.
Which free Chrome extension should I install first?
Apollo. The free tier is the most generous (10,000 email credits/month), and the extension does more than just data lookup. You can save contacts to lists, start sequences, and sync with your CRM from the extension itself. Grammarly comes second for the writing polish that catches embarrassing typos in outreach.
