Office manager email list: 37,820 US office managers, free to download

Sign up with your work email: the 10M+ U.S. dataset is on your dashboard, one zip of two Parquet files. Unzip it into a folder named us_10m, then run this in Python (pip install duckdb). It writes the 37,820 office managers with an email or a mobile to a CSV, each with their company, its website, industry and size, and their LinkedIn URL:

import duckdb

duckdb.sql(r"""
  copy (
    select p.FULL_NAME, p.CURRENT_JOB_TITLE, c.NAME as COMPANY, c.URL as WEBSITE, c.LINKEDIN_INDUSTRY as INDUSTRY,
           c.EMPLOYEE_COUNT_RANGE as EMPLOYEES, p.EMAIL, p.MOBILE_PHONE, p.CITY, p.STATE_CODE, p.LINKEDIN_URL
    from 'us_10m/us_smb_mid_market_persons.parquet' p
    join 'us_10m/us_smb_mid_market_companies.parquet' c on c.LINKEDIN_ID = p.CURRENT_JOB_COMPANY_LINKEDIN_ID
    where regexp_matches(p.CURRENT_JOB_TITLE, '\boffice manager\b', 'i')
      and (p.EMAIL is not null or p.MOBILE_PHONE is not null)
  ) to 'us_office_managers.csv'
""")

The pattern takes a title as written on LinkedIn, in any letter case. To cut it by state, add and p.STATE_CODE = 'CA'; by size, and c.EMPLOYEE_COUNT_RANGE = '11-50'. Every column of the file and its fill rate: the free US B2B leads dataset.

The titles the most office managers of the list hold, word for word. Titles held by fewer than 10 people aren't shown.

By the state on their LinkedIn profile. California holds 11.1% of them, Texas 9.6%.

By their company's industry on LinkedIn, the 10 largest. Construction comes first, with 12.2% of them.

By the employee range on their company's LinkedIn page. The free file holds companies of 11 to 500 employees. The 50M+ dataset holds every size: 190,456 office managers, 46,708 with an email and 85,313 with a mobile. It unlocks once 3 people you invited sign up.

Each email in the file comes with EMAIL_VALIDATED_AT, the date it was last verified: 19,062 of the 19,177 emails of these office managers (99.4%) were last verified on or after August 1, 2026. A person's job as it is today, their title and company, is the LinkedIn profile behind their URL: the LinkedIn profile API, $1.25 per 1,000 through Up2Data.
