Estimate reputation from weighted security and delivery indicators. Benchmark sender trust against practical risk thresholds. Spot weak controls early and strengthen inbox placement safely.
| Scenario | SPF % | DKIM % | DMARC % | Complaints % | Bounces % | Blacklist Hits | Open % | Domain Age |
|---|---|---|---|---|---|---|---|---|
| Healthy B2B Program | 99 | 98 | 97 | 0.08 | 0.60 | 0 | 31 | 42 months |
| Unstable Acquisition Push | 90 | 88 | 84 | 0.90 | 4.20 | 2 | 12 | 5 months |
| Recovering Newsletter List | 96 | 95 | 93 | 0.22 | 1.10 | 0 | 24 | 18 months |
This calculator uses a weighted heuristic score from 0 to 100. Each input becomes a normalized subscore. Positive factors keep their percentage values or scale upward toward 100. Negative factors, such as complaints, bounces, blacklist hits, and spam traps, reduce their subscores as they rise.
Weighted Reputation Score = Σ (Subscore × Weight)
Weights: SPF 10%, DKIM 10%, DMARC 10%, complaints 15%, hard bounces 10%, blacklist status 12%, spam trap exposure 10%, engagement 6%, unsubscribe control 5%, domain maturity 4%, volume consistency 4%, and list hygiene 4%.
Interpretation bands: 85–100 Excellent, 70–84.99 Good, 55–69.99 Watchlist, below 55 Critical.
This model is educational. It estimates sender reputation from supplied metrics and does not replace live mailbox provider, DNS, or blacklist checks.
It estimates how trustworthy a sending program appears based on authentication, complaint behavior, bounce quality, engagement, list hygiene, and exposure signals such as blacklist or spam trap events.
No. It scores the inputs you provide. Use it for internal assessment, planning, and reporting, then combine it with actual DNS, blocklist, and provider-specific monitoring tools.
Complaints are one of the strongest negative trust signals. Even modest increases can reduce inbox placement, increase filtering, and indicate targeting or consent problems.
Use your internal hygiene evaluation. Consider suppression accuracy, validation coverage, inactive pruning, role-account handling, source quality, and frequency of cleanup reviews.
No. A young domain can still score well with strong authentication, clean lists, stable warm-up, and low complaints. Age matters, but behavior matters more.
Scores above 85 suggest a strong baseline. Scores from 70 to 84 indicate acceptable conditions, though targeted improvements may still reduce future delivery risk.
Yes. Campaign-level values are useful for comparing segments, testing acquisition sources, or spotting short-term risk. Domain-wide values are better for executive reporting.
They reveal whether recipients welcome your mail. Weak engagement or rising unsubscribes often signal poor targeting, low relevance, or excessive send frequency.
