Software and TechnologyEmail Deliverability4HighEmail Marketer or Sender$ implied

Email deliverability is silently killed by DNS infrastructure misconfigurations (like SPF exceeding lookup limits) that are hard to diagnose manually.

Existing deliverability tools focus on copy and reputation, not deep DNS and infrastructure debugging. There is no purpose-built tool that automatically validates SPF, DKIM, DMARC, and DNS lookups and provides actionable fixes.

App Concept

InboxDebugger

InboxDebugger is a SaaS platform that automatically scans and validates your email sending infrastructure (SPF, DKIM, DMARC, DNS lookups) against best practices and provider requirements. It flags issues like too many SPF lookups, missing records, or reputation problems before they hurt deliverability. Unlike generic email tools, InboxDebugger gives you a DevOps-style audit and step-by-step fix instructions.

Key Features

Automated DNS infrastructure scan (SPF lookup count, DKIM signing, DMARC policy)
Actionable alerts with fix steps for misconfigurations
Sender reputation monitoring and IP warm-up recommendations
Campaign pre-flight checklist before sending

Target Users: Email marketers, deliverability consultants, and senders of any size who need to ensure their technical email setup meets provider standards.

Revenue Model: $49/mo per domain for scans and monitoring, with a $199/mo agency tier supporting multiple domains and advanced diagnostics
