Build a sharper Columbia 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 Columbia file, so tick these only when you want a smaller, cleaner CSV.

The Columbia roster at a glance
Email Lists USA holds 97 Columbia professional engineers with a current licence and a working email address. Every row comes from the Virginia, New Jersey, Florida and Michigan licence registers (Columbia-based engineers also licensed in Virginia, New Jersey, Florida or Michigan): 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. 3 of them (3%) list a phone, below the national 38%.
A city count is a subset of the Maryland file: about a third of Maryland rows carry no office city, so "97 Columbia engineers" is what we can place in Columbia — not every Columbia licensee.
The most common Columbia engineer inbox domains are gmail.com (39), hotmail.com (9), verizon.net (4): 60 (62%) use a personal address such as Gmail or Yahoo and 37 (38%) 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.
Phone coverage is lower than usual here: 3% against 38% nationally.

| verizon.net | 4 | 4% |
