Ensure transactional email resilience and automatic failover when providers outage

Ensure transactional email resilience and automatic failover when providers outage targets a $4.0B = 200K companies × $20K ACV total addressable market with medium saturation and a year-over-year growth rate of 10% YoY growth in cloud communications and email infrastructure spending (based on growth in cloud API services and ESP markets).

Key trends driving demand: Consolidation risk and outages — repeated ESP incidents raise sensitivity to single-provider risk and create demand for resilience tooling.; Developer-first infrastructure — API-driven services and SDKs make adding a control plane easier and accelerate adoption among engineering teams.; Deliverability focus — inbox placement and deliverability analytics are increasingly mission-critical as regulators and ISPs tighten anti-abuse measures, creating demand for aggregated telemetry.; Serverless + managed queues — serverless functions and managed queueing services lower the cost of building retry/replay logic, making multi-ESP orchestration feasible for small teams..
