gsjmedia publishes free, pre-built B2B lead lists and verified email databases
covering 452 categories. They are browsable and downloadable at no cost, with no
card and no signup wall.

## What is available?

Two collections sit on the page.

**Lead lists.** 452 categories of pre-built B2B contact lists, filterable by
category and searchable by keyword. A bundle option covers all 447 email lists
in one download.

**Databases.** Six larger verified email databases, four available now and two
in progress.

## Why is this free?

The lists are a genuine giveaway rather than a lead magnet with a catch. They
are useful on their own, and the constraint they expose is the point: a list is
only half of an outbound motion. Sending to it from an unwarmed inbox on a main
domain destroys deliverability before the copy matters. That is the problem
gsjmedia sells the fix for.

## What do you do with a list once you have it?

A list needs three things before it produces meetings.

**Verification.** Contact data decays continuously. Verify every address before
it enters a sequence, not after bounces appear.

**Infrastructure.** Send from dedicated domains separate from your main one,
authenticated with SPF, DKIM and DMARC, on inboxes warmed before the first cold
send. This is decided before a word of copy is written.

**A reason to reply.** Generic templates against a cold list produce nothing.
Copy has to reference something real about the recipient's business.

gsjmedia runs all three as a service, but the lists themselves are free whether
or not that is of interest.
