You have a list. Maybe it came from a webinar, a conference badge scan, or an export someone pulled from your CRM two quarters ago. It has names, companies, and a few job titles that were accurate at some point.

What it does not have is phone numbers, verified emails, or any sense of which rows deserve your morning.

So you look for a way to enrich a csv of leads. The first path most reps find is a vendor upload. Drop the file, wait, get it back fuller. That works until you read the fine print, watch the credits drain, or realize your file is now sitting on someone else's server.

There is a second path. It is slower on paper and faster in practice, because it gives you a read on the account instead of a fuller row.

You open a prospect profile, click for the email, and watch a counter tick down. That single click has a price attached to it. Whether you feel that price depends entirely on how your vendor decided to bill you.

Email finder pricing splits into two camps. Per-credit models charge you for every reveal. Per-seat models charge you a flat fee per user and cap what you get inside that seat. Both sound reasonable on a pricing page. Both behave differently once you are running 80 touches a day and trying to build real pipeline.

This breakdown covers how each model works, where each one quietly costs you more than expected, and how to pick the one that fits how you prospect.

You bought the data. You paid for the seats. Your reps still complain that the phone numbers go nowhere.

Vendor accuracy claims are marketing statements. They describe a database in aggregate, not the slice of records your team touches every day. The only number that matters is how your data performs against your territories, your personas, and your buying groups.

That means you need a repeatable contact data accuracy test. Not a one-time audit. A method you run every quarter, against every provider, with the same rules each time.

This post gives you that method. It covers sampling, scoring, benchmarking, and what to do with the results once you have them.
