The goal of this article is to help users understand at which point in the list creation flow leads get enriched, what determines whether a lead makes it into a list, and when credits are consumed.

How enrichment works

Enrichment does not happen while you're building your search or browsing sample results. It happens at one specific moment: when you save the list.

When you save a list — or when monitoring adds new leads to an existing list — Topo enriches each lead by looking up their contact information. The key requirement for a lead to be imported into your list is a valid email address. If Topo cannot find a valid email for a contact, that contact is not added to the list.

This means the number of leads in your list may be lower than the number of leads the agent originally found. For example, if your search surfaces 10 matching contacts but only 3 of them have a verified email address, only those 3 will appear in your list.

When are credits counted?

Credits are consumed at the same moment enrichment happens — when the list is saved. Each lead that is successfully enriched (i.e. a valid email address is found) counts as one credit.

Leads that fail enrichment because no valid email can be found do not consume any credits.

The same logic applies to monitoring: each time the agent adds new leads on your chosen schedule (daily or weekly), enrichment runs on those new leads and credits are counted for each one that passes.

Summary

1. You build a search and review the sample results — no enrichment, no credits used.

2. You save the list (or monitoring adds new leads) — enrichment runs on each lead.

3. Only leads with a valid email address are imported into the list — one credit per enriched lead.

4. Leads without a valid email are excluded and do not cost any credits.
