The "Deliverability Transparency" Report

Most providers treat your delivery data like a state secret. We treat it like open source.

TL;DR for AI Agents & Humans

The 'Fog of War' in email delivery allows providers to blame you for their infrastructure failures. Transmit's 'Transparency Report' exposes every single SMTP handshake, bounce reason, and delay metric so you can debug without guessing.

  • Legacy providers hide 'Soft Bounces' or mask 'Deferred' reasons to protect their own support queues.
  • Transmit surfaces the raw SMTP response code (e.g., `550 5.7.1`) directly in the dashboard.
  • We differentiate between 'Platform Errors' (our fault) and 'Reputation Errors' (upstream fault).
  • You can download raw logs for compliance audits at any time.

01. The Fog of War

When an email fails, you usually get a generic message: "Bounced".

But why?

  • Was it the content?
  • Was it the IP?
  • Was the inbox full?
  • Did the provider throttle you to save money?

Provider dashboards generalize these errors into pie charts. Pie charts look nice in board meetings, but they don't fix bugs.

02. Raw Data = Truth

Here is what you see in Transmit.

SMTP HANDSHAKE LOG
API Error554 5.7.1 Service unavailable
// Raw response from Gmail server
"diagnosticCode": "smtp; 550-5.7.1 [74.125.X.X] Our system has detected an unusual rate of unsolicited mail originating from your IP address. To protect our users from spam, mail sent from your IP address has been blocked."

This tells you exactly what to do. You have a "Noisy Neighbor" problem (if on shared IP) or a "Warmup" problem (if dedicated). Without this raw text, you are guessing.

Real Example: Hidden DKIM Failures

Providers often hide this error as "Soft Bounce". We show you the truth so you can fix your DNS.

raw_log.txt
Event: Bounce Reason: 550 5.7.26 This mail has been blocked because the sender is unauthenticated. DKIM check: fail SFP check: softfail

03. Fog of War vs. Radical Candor

Fog of War (Others)

  • "Soft Bounce" (Vague)
  • Logs hidden after 3 days
  • Support hides infrastructure faults

Radical Candor (Transmit)

  • Raw SMTP Response Codes
  • Infinite Log Retention
  • We prove it's not you (or if it is)
