SEG Classification

Two trailing CSV columns tell you what kind of mail server sits in front of each domain, so you can tune sending strategy before you hit a spam filter:

seg_classification Gateway verdict (values below)
seg_provider Named provider, e.g. "SEG: Proofpoint", "Google"

What each seg_classification means and what to do:

  • external_seg — Domain is behind a secure email gateway (Proofpoint, Mimecast, Barracuda...). These gateways aggressively filter cold mail; warm these leads slowly or deprioritize them.
  • no_email — Domain has no mail records, so any address there is undeliverable; exclude these from campaigns.
  • direct_google / direct_microsoft — Standard Google Workspace or Microsoft 365 mail. Apply your normal sending rules.
  • other_or_unknown — Self-hosted or unrecognized mail server. Treat as standard sending with normal monitoring.
  • blank — No verdict available for this row (feature off or domain not yet classified).

This classification is a background domain lookup, not an enrichment provider — it does not affect email finding or job counters.
