Got a sheet full of email addresses and want to know which ones are real estate agents? GetRosters Agent Check marks them for you.

How it works
Open your sheet and choose Extensions, then GetRosters Agent Check, then Check emails. Pick the column with the emails and press Check. Agent Check compares each address with the GetRosters agent files for Australia, the United States, Canada, the United Kingdom, Ireland and New Zealand, and adds six columns to the right of your data: Agent, Agency, Location, Role, Last seen, and a link to the agent list for that state or country.

"Not found" means the address is not in our files. It does not mean the person is not an agent. Each address is checked once, even if it appears in several rows, and the add-on asks before it replaces results from an earlier check.

What leaves Google
Only a short fingerprint (hash) of each email you check, never the email itself. We look it up and keep nothing. The fingerprint is worked out inside your Google account by the add-on. Your emails, names and other cells stay in your sheet.

About GetRosters
GetRosters (getrosters.com) publishes real estate agent contact lists by country and state. Agent Check sends the fingerprints to the GetRosters service at getrosters.com, which matches them against the same fingerprints of the agents in its files and sends back the matches. Agents who ask to be removed from GetRosters are left out of the results.

Permissions
It reads and writes only the spreadsheet you use it in, shows its sidebar, and uses your Google sign-in so GetRosters can count your daily checks. Google adds basic profile access (your name and email address) to every Marketplace app. Agent Check does not use it, and GetRosters never stores or logs it.

Free and Pro
Free: 2,000 checks a day. Pro: US$190 for one year, paid once with no automatic renewal, for 20,000 checks a day. Both run exactly the same checks. Pro is bought from the sidebar's "Go Pro" link. Details: https://getrosters.com/sheets/pricing/
