RocketReach claims 98% accuracy for verified contacts, compared to Hunter.io’s 95% and Apollo’s 90-92%. However, accuracy varies by data type: Email (98%), Phone (85%), Social profiles (95%). RocketReach excels at phone numbers and executive contacts but costs 2-3x more than competitors. Best for high-value B2B outreach where accuracy matters more than cost.

1 Lookup = 1 data field request. Example: Retrieving email + phone + social for 1 person = 4 lookups (email: 1, phone: 2, social: 1). Most users need 2-3 lookups per contact. RocketReach pricing is lookup-based, so requesting more fields per contact burns through your quota faster. Optimize by only requesting fields you’ll actually use.

RocketReach data is sourced from public records and websites, which is legal under GDPR Article 6(f) – legitimate interest. However, YOU must: 1) Document legitimate interest, 2) Provide opt-out in first contact, 3) Honor deletion requests within 30 days, 4) Avoid sensitive data processing. RocketReach provides data compliance docs, but final responsibility is yours. B2B cold email is generally allowed; B2C requires consent.

Even with 98% accuracy, always verify emails before cold campaigns: 1) Use RocketReach’s built-in verification (included), 2) Run through secondary validator (NeverBounce, ZeroBounce) for catch-all detection, 3) Check MX records programmatically, 4) Start with small test batch (50 emails) to measure bounce rate. Aim for <2% bounce rate to protect sender reputation.

Yes. API limits: 60 requests/minute (Pro), 120 requests/minute (Ultimate), 10 requests/second max burst. Bulk lookup endpoint allows 100 contacts per request. Exceeding limits returns 429 error with retry-after header. Best practice: implement exponential backoff, batch requests, cache results, and monitor quota usage via API dashboard to avoid mid-campaign failures.
