Executive Summary

Many app and e-commerce teams lose critical transactional emails to spam filters—order confirmations, OTPs, and password resets—creating revenue leakage, increased support load, and broken user flows; this pain point is acute for developer-led teams at SMBs and mid-market apps. These teams often lack observability into mailbox placement and actionable remediation, so problems are hard to diagnose and fix quickly. You could build an API-first deliverability platform that runs seeded inbox-placement tests, aggregates signals (ESP telemetry, engagement, DMARC/BIMI status), and surfaces prioritized, automated remediation playbooks with CI/CD integration and alerting. Position it as a self-serve developer tool with programmatic hooks, dashboards, and a $3,000 ACV target for typical customers. The opportunity is timely: TAM ~ $3.0B (1,000,000 potential customers × $3,000 ACV), an overall Market Score of 88/100 and Revenue Potential of 82/100, driven by stricter mailbox filtering and rising DMARC/BIMI adoption. Developers’ preference for API-first observability tools further amplifies demand for a programmable solution that fits into existing workflows. To compete, prioritize measurement accuracy and actionability—aggregate multi-provider signals, automate fixes, and integrate tightly into CI/CD rather than just producing reports—while being realistic about the two main challenges: mailbox-provider opacity and the cost/complexity of building reliable seed and telemetry infrastructure.

Market Opportunity

Reduce transactional email spam hits by improving deliverability signals targets a $3.0B = 1,000,000 app/e-commerce businesses × $3,000 ACV (transactional deliverability tooling/services per year) total addressable market with medium saturation and a year-over-year growth rate of 10-15% CAGR — email infrastructure and deliverability tooling have steady growth as more businesses rely on transactional messages; source: industry reports on email API and deliverability services.

Key trends driving demand: Higher filtering accuracy at mailbox providers — this increases demand for third-party tools that can diagnose inbox placement and suggest fixes.; API-first adoption among developer teams — developers prefer programmatic, self-serve tools they can integrate into CI/CD and observability stacks.; Rise of DMARC/BIMI adoption — as authentication becomes mandatory for brand alignment, customers need simpler tools to implement and monitor these records.; Increased regional variability — different mailbox providers and ISPs have distinct reputation signals, creating value for continuous seed-list testing and geographies-aware routing..

Key competitors include Postmark (Wildbit), SendGrid (Twilio SendGrid), Mailgun (Pathwire).
