How It Works

Step 1

Paste Your Campaign

Add your sending domains and paste your prospect email list or domains.

Step 2

We Analyze Everything

14 signals per domain + sender health + domain age + sender-prospect matching.

Step 3

Get Your Report

CSV with every email mapped to deliverability status + sender recommendations.

We Handle The Details

Duplicate emails?

We automatically deduplicate. 500 emails from 18 domains? We check 18 domains, map results back to all 500.

Public emails (Gmail, Yahoo)?

We detect 60+ public providers and filter them out. No wasted checks on unreachable inboxes.

Mixed input formats?

Paste full email addresses, bare domains, or both. We parse everything — your-prospect@their-company and their-company.com both work.

Multiple sending domains?

Up to 100 sending domains. We check each one's health and match the best sender to each prospect.

What We Check

Sender Health Check

SPF, DKIM, DMARC, blacklist status, and domain age for your sending domains.

14 Deliverability Signals

Security gateways, DMARC policy, BIMI, MTA-STS, and more for each prospect.

Sender-Prospect Matching

We recommend which sending domain to use for each difficulty level.

3 CSV Reports

Campaign results, sender health, and sender-prospect matching — all downloadable.

Domain Age Matters

We check how old your sending domains are — new domains need careful warmup.

Email-Level Mapping

Results map back to your original emails, not just domains. Filter your CRM directly.

Your 3 CSV Reports

Campaign Results CSV

One row per email. Includes inbox risk score, difficulty level, email provider, security gateway detection, DMARC/SPF/DKIM/BIMI/MTA-STS status, blacklist check, and the best sending domain for each recipient.

Sender Health CSV

Health report for each of your sending domains. Domain age, health score (0-100), SPF/DKIM/DMARC configuration, blacklist status, and warnings about domains that need warmup or fixes.

Sender Matching CSV

Maps each prospect domain to the best sending domain based on difficulty level. Shows the primary recommendation, an alternative, and the reasoning behind the match.

All reports delivered by email and downloadable from the results page for 24 hours.

This simulator analyzes public DNS records to estimate inbox deliverability. Actual delivery depends on many factors including email content, sending reputation, IP warmup, and recipient behavior. Results are estimates, not guarantees.
