Microsoft SNDS + JMRP Setup Checklist

If any of your outbound mail hits @outlook.com / @hotmail.com / @live.com / corporate Microsoft 365 tenants, SNDS is the visibility layer you need.

SNDS (Smart Network Data Services)
  1. Visit sendersupport.olc.protection.outlook.com/snds/
  2. Sign in with a Microsoft account (personal or work).
  3. Submit your sending IP range. Microsoft requires you to demonstrate ownership — usually via the reverse-DNS record on the IP.
  4. Wait for approval. Typically 1–2 weeks.
  5. Review the per-IP dashboard weekly. Watch the spam complaint rate and the RCPT count for unusual jumps.
JMRP (Junk Mail Reporting Program)
  1. Visit sendersupport.olc.protection.outlook.com/pm/junkmail.aspx
  2. Enroll your domain and a reporting endpoint.
  3. Microsoft will forward complaints from Outlook.com / Hotmail / Live users marking your mail as junk.
  4. Process complaints into your suppression list within 24h to avoid reputation decline.
What it does

Walks through the unusual SNDS sign-up flow (per-IP, requires reverse DNS, approval can take 1–2 weeks) and the JMRP enrollment (separate signup).

When to use

After 30 days of consistent sending to Microsoft addresses. Before that, SNDS has nothing to show.

FAQ

Per-IP vs per-domain — why?+

Microsoft assigns reputation primarily at IP level (Google does too but weights domain heavier). On shared IPs, SNDS is less actionable; on dedicated IPs, it's gold.

Nate built Outsolvi after watching every email-tracking tool he had ever used lie to him about opens. Outsolvi runs Tier 1 to 5 confidence scoring on every open, native in Outlook and Gmail, so the number on the dashboard is one a rep can actually act on.
