Email and phone enrichment

This is where most of the money in prospecting is spent, and where most of it is wasted. The job is simple to state: turn a name and a company into an email address and a mobile number that actually work. Three things decide the cost. First, whether the provider bills on results or on attempts. Billing on result means a bad list costs nothing to try; billing per row queried means you pay for every miss, and on European mobile data the miss rate is high. Second, the hit rate on your own market, which is the only benchmark that predicts anything. A provider at half the price that finds a third as many contacts is more expensive per usable contact, and the invoice will never show you that. Third, the order you call providers in. Cheapest first, stop at the first hit, and let the expensive one meet only the rows nobody else could find. Getting that order backwards costs around forty percent more for exactly the same data. Expect one credit for a verified email and around ten for a direct mobile as the market rate. Verification, at a tenth of a credit, is the cheapest insurance in the whole stack.
