Inbox Placement, Backed By the Mailbox Providers Themselves

Most “deliverability dashboards” are seed-list theatre. ApexMail reads the actual signal that Gmail and Outlook publish about your domain — and acts on it.

What We Measure

Google Postmaster Tools

  • Domain reputation: HIGH / MEDIUM / LOW / BAD
  • IP reputation by sending IP
  • SPF, DKIM, DMARC pass ratios
  • User-reported spam ratio
  • Inbound and outbound TLS rates
  • Delivery error breakdown

Microsoft SNDS

  • Filter result: GREEN / YELLOW / RED
  • Complaint rate per IP
  • Spam-trap hits
  • Recipient acceptance ratio
  • Junk Mail Reporting Program (JMRP) feedback

How We Act on It

Every six hours, ApexMail’s reputation scheduler:

  1. Pulls the latest stats for every domain and IP you send from.
  2. Scores them on a transparent 0–100 scale (the algorithm is in our docs).
  3. Bands the score: Green (≥70), Amber (40–69), Red (<40).
  4. Throttles outbound to that provider automatically:
    • Green → 0% throttle (full speed)
    • Amber → 50% throttle (probabilistic deferral)
    • Red → 90% throttle (near-stop, alert sent)
  5. Alerts the right humans — webhook, email, or Slack — when a band drops.

When your reputation rebounds, throttle releases without a human in the loop.

Why This Matters for Your $100k MRR

A single bad batch can put a sender domain on Gmail’s BAD list for 30+ days. Most ESPs give you the bad news in their next Quarterly Business Review. ApexMail caps the blast radius the same shift — your high-volume tenants keep delivering through clean lanes while the impacted domain cools off.

Per-Provider Throttle Overrides

Operators can pin a throttle (e.g. 100% for two hours during a known incident) without code changes. Every decision is logged with score, band, and source for audit and customer transparency.
