Build a sharper Colorado list
Start from the whole file and tighten it. Narrowing by phone or inbox is free — the count drops, the price doesn't.
Narrowing never changes the price: a slice costs the same as the whole Colorado file, so tick these only when you want a smaller, cleaner CSV.

The Colorado roster at a glance
Email Lists USA holds 1,280 Colorado professional engineers with a current licence and a working email address. Every row comes from the Florida, Michigan, Virginia and New Jersey licence registers (Colorado-based engineers also licensed in Florida, Michigan, Virginia or New Jersey): each address is the one the licensee filed with the regulator, so there is no firm to filter by and the file is people rather than companies. Each row says so in its Data Source column. 453 of them (35%) list a phone, below the national 38%.
By office city, Denver leads with 228 engineers, then Littleton (83) and Colorado Springs (83); 7 Colorado cities have 50+ engineers on file and their own list. 1 rows (0%) carry no office city and are sold only in the state file.
The most common Colorado engineer inbox domains are gmail.com (567), yahoo.com (68), hotmail.com (42): 812 (63%) use a personal address such as Gmail or Yahoo and 468 (37%) a work address on a company or own-business domain. We keep every address with its domain (never the full mailbox until you buy) so you can see these are real business and personal inboxes, not a guessed pattern.

Colorado engineer data — straight answers
The things people ask before they buy the Colorado list, answered with this build's numbers.
Why is this Colorado professional engineer list smaller than others?
Because an engineer is only in this file if we hold the contact email the licensee filed with the Florida, Michigan, Virginia and New Jersey licence registers (Colorado-based engineers also licensed in Florida, Michigan, Virginia or New Jersey).
This build is dated Sep 29, 2026. A larger count usually means addresses no source publishes.
Which firms do the Colorado engineers work at?
No firm is named: every row in this file comes from the Florida, Michigan, Virginia and New Jersey licence registers (Colorado-based engineers also licensed in Florida, Michigan, Virginia or New Jersey), and each address is the one the licensee filed rather than an employer's. You buy the whole state, and the Data Source column says so on every row.
How much does the Colorado professional engineer email list cost?
$69, one-time, for the whole Colorado file (1,280 rows) as an instant CSV — no subscription, no account. Need a single city instead of the state? Every Colorado city with 50 or more engineers has its own file on this site, from $39. 25 unsealed rows are free first. The file holds name, email, phone (35% of rows), city, state.
