Gmail and kw.com top the mail domains in the Wisconsin file
In the Wisconsin rows gmail.com is the most used single domain, at 803 addresses, with kw.com 48 behind on 755 and remax.net third on 658. Taken together, free mail services account for 17% of the file and business domains for the remaining 83%.
The mix changes from brand to brand. In the Wisconsin rows, Compass agents write from compass.com almost without exception (243 of 244), and 658 of the 669 RE/MAX agents use remax.net. Real Brokerage and Berkshire Hathaway HomeServices go the other way: for both, gmail.com is the first domain, covering 270 of 517 and 174 of 298 agents.
95% of the Wisconsin rows also give a phone number. We first saw 628 of the Wisconsin rows in October 2026; that month marks their arrival in our file, not a new license or a change of firm.
Coldwell Banker ahead of Keller Williams in the Wisconsin file
Coldwell Banker, not Keller Williams, leads the Wisconsin rows, with 915 agents against 831. In our US file the two swap places (Keller Williams 86,653, Coldwell Banker 69,745). Coldwell Banker holds 20% of the branded agents in the Wisconsin rows, against 15% in our US file.
The next three brands here, RE/MAX, Century 21 and Real Brokerage, also carry more weight than in our US file: 14%, 13% and 11% of the branded Wisconsin rows, against 10%, 8% and 7% across the US file. Keller Williams, at 18%, sits slightly under its 19% US share.
The two largest Coldwell Banker company names in the Wisconsin file are Coldwell Banker Realty (328) and Coldwell Banker Real Estate Group (323); the largest Century 21 name is CENTURY 21 Affiliated (383).
A few brands with big totals in our US file hardly appear in the Wisconsin rows: HomeSmart has 17 Wisconsin agents (24,548 in the US file), Sotheby's International Realty 7 (9,496) and LPT Realty 2 (12,578). Epique Realty goes the other way. Wisconsin holds about 1% of the branded rows in our US file, yet 3% of Epique's: 136 of 3,965.
Appleton, Whitefish Bay, Madison and Milwaukee lead the Wisconsin file
Where a row gives an office town, the row is filed under it. Appleton has the most Wisconsin rows of any town, 347, ahead of Whitefish Bay (328), Madison (252) and Milwaukee (241).
The biggest company-and-town group in the Wisconsin file is Keller Williams in Whitefish Bay: 325 of the 328 rows in that town's file. Keller Williams rows carry the brand alone as their company, so each Keller Williams line in the table counts every Keller Williams agent in one town; the next two such lines are New Berlin (121) and De Pere (94). In Mequon, 99 of the town's 107 rows are filed under Coldwell Banker Realty.
Appleton is more mixed: its largest groups are Coldwell Banker Real Estate Group (90), Keller Williams (82) and CENTURY 21 Ace Realty (69). In Madison the leading groups are Compass (63), Real Broker (63) and Keller Williams (56).
The table does not group RE/MAX rows by company, so RE/MAX, with 669 agents in the Wisconsin file, has no line in it. By office town its agents are most numerous in Greenfield (55) and New Berlin (43).
