Technographics are data about the technology a company uses: its CRM, email platform, marketing automation, hosting, analytics, payment provider and the rest of the stack. They are collected by scanning websites for scripts and tags, reading DNS and mail records, and parsing job postings. In prospecting they identify accounts that use a competitor, a complementary tool, or nothing at all; in the 2026 corpus the mail provider behind a domain predicted its verification behaviour more than any other attribute, with one German gateway alone producing a 41% unknown rate.
A technographic record is a list of detected technologies with first-seen and last-seen dates. Detection from a site scan is reliable for front-end tools and weak for back-office systems, which is why job postings and DNS fill the gaps. Stacks change on a quarterly to yearly cadence, so a last-seen date older than six months is a guess.
For email outreach the most useful technographic is the mail provider, visible in MX records. It tells you in advance whether a domain is likely to be catch-all, to refuse verification probes, or to enforce strict bounce thresholds, and it lets you plan phone or LinkedIn for the accounts where email will return unknown.
A sequencing vendor targets companies that run HubSpot but not a verification tool. A technographic filter returns 3,400 domains. MX lookup shows 2,900 on Google Workspace or Microsoft 365 and 500 on regional ISPs. The 2,900 are routed to email; the 500, whose gateways return unknown far more often, are routed to LinkedIn first.
