Outbound Infrastructure Fingerprint

live$0.004/resultEnrichment

Detects whether a company runs cold email outbound and on what stack. Finds the lookalike sending domains behind the program, the inbox provider, the sequencer, warmup and infrastructure vendors, plus SPF, DKIM and DMARC posture. One flat Clay ready row per domain.

Use Cases

  • Who buys it. Bought by vendors selling into outbound teams, who read program as "these people buy tools like mine", and by prospectors, who read the same row as "their inbox is crowded, expect a hard landing".
  • Clay enrichment column. Read a prospect's sending setup before you write to them, so you know whether their inbox is already crowded.

Features

  • A four-level runs_outbound verdict with the rule that fired
  • Lookalike sending domains, attributed by redirect
  • Inbox provider and sequencer, read from DNS
  • 40 flat fields, snake_case, one row per domain
  • Registration clustering, bought-together domains
