Deliverability data
for data people.
Your team doesn't want dashboards that hide the details. You want to see the raw deferral codes, understand why Gmail is throttling you, and query the data yourself. You want technical depth, not marketing fluff.
Finally, email intelligence built for engineers.
You need more than pretty charts
ESP dashboards hide the details
"Delivery rate: 97%" — but what happened to the other 3%? Soft bounce? Hard bounce? Throttled? Blocked? You need to see the SMTP codes, not just the summary.
No visibility into throttling patterns
Gmail is deferring your emails, but is it volume-based? Reputation-based? Time-of-day? Without the raw data, you're guessing at solutions.
Engagement decay is a black box
Users stop engaging, but when? Which cohort? How fast? You can't optimize onboarding or re-engagement without cohort-level visibility.
Technical depth without the data engineering
Deferral intelligence with SMTP context
See every deferral code: 421, 450, 452. Understand if it's throttling, reputation, or rate limiting. Track patterns by ISP and time of day.
Deliverability Analytics ->ISP-by-ISP breakdown
Gmail treats you differently than Microsoft. See delivery rates, deferral patterns, and engagement metrics broken down by provider.
ISP Performance ->Cohort engagement analysis
Track how engagement decays over time by signup cohort. Compare December signups to November. See exactly when users disengage.
Cohorts & Segments ->Bounce classification that matters
Hard vs soft isn't enough. See the actual bounce codes, understand the root cause, distinguish list hygiene from reputation problems.
Bounce Intelligence ->The data you actually need
Deferral Analysis
SMTP response codes, ISP patterns, hourly trends. Understand why ISPs are slowing you down.
