Can we have an agent for…
email triage?
Short answer: Superhuman, SaneBox, Shortwave already ship email triage tooling in 2026. Across 6 ideas roasted here, 0% were told to ship and 67% already exist — the most common verdict is ALREADY EXISTS, YOU'RE LATE.
Inbox-zero agents are how Superhuman stayed a $20-a-month product. The bar is high; the second mover usually loses.

Is a email triage agent worth building?
Sample email triage verdict
“Congratulations, you've reinvented the $12 automatic drip irrigation timer from Amazon, but with more GitHub commits.”
Ship it anyway →Target commercial plant rental companies — they manage 500+ office plants across clients and have zero real-time monitoring. That's the wedge.
Agent-Readiness Score
Ready to scaffold today. PlantNanny 9000 could be a working prototype in a week.
- Memory ↗25/25
Stateless or single-session — minimal memory layer.
- Tools ↗11/25
Crowded market: at least 8 integrations to compete.
- Policy ↗24/25
Narrow policy surface — bounded inputs, predictable outputs.
- Evals ↗22/25
Established eval pattern — golden datasets and public benchmarks already exist.
DETERMINISTIC SCORE — DERIVED FROM EXISTING ANALYSIS, NO SECOND LLM CALL
What could go wrong with a email triage agent?
Which OWASP Agentic/MCP Top-10 risks email triage agent ideas tend to carry, across the 6 real ideas roasted here. Derived deterministically from each idea's analysis — not a generic checklist.
A second MCP server's output reaches the agent's context and steers it. Mitigation: source-tag every tool result, refuse cross-server instructions.
Chaining tools enables an effect neither alone permits (read+exfiltrate). Mitigation: dataflow review, taint tracking, capability slicing.
The agent has more tool privileges than the user task requires. Mitigation: per-task capability scoping, explicit confirmation for destructive ops.
Malicious or impostor MCP server installed via marketplace. Mitigation: signed manifests, reproducible builds, allow-list of providers.
Educational mapping based on the OWASP GenAI/MCP Top-10. Not a security audit of any specific product.
Best one-liner
“Congratulations, you've reinvented the $12 automatic drip irrigation timer from Amazon, but with more GitHub commits.”
