Pricing in detail

Plan	Price/month	Credits	Email sequences	Intent data
Free	$0	10,000	2 active	No
Basic	$49	60,000	Unlimited	No
Professional	$79	120,000	Unlimited	Yes (basic)
Organization	$119	Unlimited	Unlimited	Yes (advanced)

Pro tip: 1 credit = exporting 1 contact. On Basic ($49/mo, 60,000 credits), you can theoretically export 60,000 contacts per month — more than enough for most B2B teams.

DACH data quality: an honest assessment

Data type	US/UK	DACH	Rating
Email addresses	85-90%	60-70%	Medium
Phone numbers	70-80%	40-50%	Weak
Company size	90%+	85%+	Good
Industry	90%+	85%+	Good
Tech stack	80%+	70%+	Okay
Funding data	90%+	60-70%	Medium

Bottom line: For company data and filtering, Apollo is solid in the DACH region. For email addresses, you should additionally verify (NeverBounce, ZeroBounce) or use Apollo as one source in Clay’s waterfall.

Strengths

1. Price-to-value: for $49/mo you get a database + outreach + analytics
2. Easy to get started: intuitive UI, fast setup, good onboarding docs
3. Large database: 275M+ contacts, well maintained
4. LinkedIn integration: Chrome extension for direct import
5. Email sequences included: no separate tool needed for email outreach

Weaknesses

1. DACH data quality: email accuracy under 70% in the German-speaking region
2. No waterfall: only one data source — no fallback cascade
3. Limited AI features: basic personalization, no Claygent equivalent
4. Email sending: works, but Instantly/Lemlist are more specialized
5. No multi-account rotation: one sender per user

Conclusion

Apollo.io is the best entry-level tool for B2B prospecting: affordable, intuitive, all-in-one. For the US/UK market, it’s often enough as a standalone tool.
