Free vs. Premium: Which KNOX Plan Fits You?

KNOX Data Magic works with a prepaid credit model: every cleaning or enrichment of a contact consumes credits. No subscription, no base fee, no contract term. You buy credits when you need them — with volume discounts on larger packages. As a reference point: the entry package is €39 for 10,000 credits.

Why prepaid? Because, honestly, I consider subscription models the wrong mechanic for data hygiene. Your list does not grow at the same pace every month, and you do not run a full-list clean-up weekly. You should pay when work gets done — not because a month has passed.

The free plan fits if you want to get to know KNOX, maintain a small list, or only need basic hygiene for now: normalizing names, fixing obvious errors, getting a feel for the data quality of your list. It is deliberately built so that you experience real value without entering payment details.

Switching to credits pays off as soon as one of these three things happens: your list grows steadily with new contacts — then continuous background enrichment becomes worthwhile. You want to enrich deeper: gender, age cohort, zip-code-based regional data, B2B detection. Or you are planning a large clean-up of your existing base, say before a system migration or a reactivation campaign.

The rule of thumb from my consulting practice: as soon as segmentation and personalization are part of your strategy — and not just a good intention —, the credits pay for themselves through better campaign performance. You will find the matching calculation aid in my article on the costs of bad data hygiene.

Remember: start free. Upgrade when your strategy demands it — not before.
