Who can benefit from the Apollo Extension?
The Apollo Chrome extension is particularly valuable for sales professionals heavily involved in outbound prospecting:

- Account Executives (AEs): Who need quick access to contact data and company insights while researching accounts or engaging prospects.

Apollo Chrome Extension privacy & data accuracy
Apollo claims high accuracy rates for its data (around 84% email match rate, 90%+ overall accuracy), leveraging real-time validation and diverse sources.
While Apollo is broadly GDPR and CCPA compliant, it claims that its Chrome Extension does not apply GDPR protections when pulling contact data from LinkedIn or websites. This means contacts from the EU or UK aren’t covered by the same safeguards when sourced through the extension.
However, there’s a privacy nuance regarding GDPR: Apollo states that its Chrome Extension does not apply GDPR data protections when extracting contact information directly from LinkedIn or websites. This implies that if you use the extension to source contacts based in the EU or UK, those individuals might not have the standard GDPR opt-out or data rights applied by Apollo for that specific data capture instance.
Note 💡: Apollo advises users to manually verify the location of prospects sourced via the extension, especially if targeting EU/UK individuals, to ensure compliance with relevant data privacy regulations before adding them to outreach sequences.

FAQs

Which tools does Apollo Chrome Extension integrate with?
The extension primarily overlays and interacts with LinkedIn (Free/Sales Nav), Gmail, and Google Calendar. It allows sending data to Apollo lists/sequences. While Apollo as a platform integrates deeply with CRMs like Salesforce and HubSpot, pushing contacts directly to these CRMs from the extension overlay typically requires a paid Apollo plan (though direct-to-HubSpot push might have some availability).
Is the Apollo extension free?
Yes, the extension can be used with Apollo’s free plan, which includes limited monthly credits for viewing emails/phone numbers on LinkedIn and basic Gmail/Calendar features. Advanced features like CRM sync, bulk actions, and advanced filters require a paid plan, starting around $39-$49/month (billed annually).
What’s a good alternative if Apollo isn’t the right fit?
The best alternative depends on why Apollo doesn’t fit. If you need more automation for your entire prospecting process (beyond just lookups), PhantomBuster is designed for that. If GDPR compliance and straightforward global lookups are paramount, Lusha is a strong choice. If you primarily target the European market, Kaspr offers excellent data coverage there. Evaluate based on your specific needs for data, automation, compliance, and budget.
