A pattern is a convention, not a guarantee: it holds for most mailboxes and fails on
collisions and legacy accounts. Verify before sending.

## Enriching a list rather than one company

This page covers T-Mobile alone. To do the same across a whole list of accounts -
firmographics, decision makers, verified emails and phone numbers - Derrick enriches it
in its web app (nothing to install), in Google Sheets, through an MCP server or a REST API.
Billed per verified match; the free plan includes 100 credits per month.
