How Rackspace Email use was found
We read the MX and SPF records of 75,722 company domains and found Rackspace Email on 230. The companies come from six lists: the Fortune 500, the Inc 5000, unicorns, Y Combinator, a SaaS list and the Tranco top 10,000.
Industry, employee band and country were labelled by a language model from each company's homepage, since the company databases we tried match big companies to the wrong record (one listed Principal Financial Group as a food producer with 11 to 50 staff). We checked 200 random rows against each company's homepage with a second, larger model: industry was wrong on 2.6%, country on 2.1%, and the employee band was off by one band on 12% and by two or more on 2.0% of rows. Inc 5000 and Y Combinator companies keep the figures they filed themselves.
The list is not every Rackspace Email customer. A company that uses Rackspace Email only internally and never names it in a job post or loads it on its homepage is not on it. Method. Source: Installmap, October 2026.
