What these numbers mean
Email coverage here is 13%, below the 29% statewide. Expect to work more of this list by phone.
8 of the 23 companies (35%) have no website at all. That is usually the clearest sign a business is not being marketed to by anyone, which is either an opportunity or a warning depending on what you are selling.
Only 1 of these name an owner. Owner names are read from the company's own site rather than guessed, so coverage varies sharply by how much these businesses publish.
None of the addresses in Vallejo, CA have been through the mail-server check yet, so every one is labelled unverified. Verification runs continuously and this figure moves.
12 of the 23 (52%) are graded a core match for HVAC contractors; the remainder are adjacent trades that turned up in the same search and are kept because they often buy the same things.
