Score breakdown
Agentic workflows that require email communication can now provision real, fully functional inboxes via API without wrestling with Gmail bot bans, SES limitations, or enterprise-only pricing — and connect directly via MCP without writing integration code.
- 01Targets AI agents needing email: Gmail suspends bots quickly, SES is outbound-only, and existing purpose-built options have steep pricing gaps.
- 02Each inbox gets a real email address with send/receive, inbound webhooks, and full conversation threading.
- 03No OAuth or human-in-the-loop required — fully API-driven.
Dead Simple Email is a new email API service built specifically for AI agents, created to solve a recurring infrastructure problem: Gmail suspends bot accounts quickly, Amazon SES is outbound-only with no inbox or threading support, and the only existing purpose-built alternatives jump sharply in price with no mid-tier option. The service gives agents their own real email addresses programmatically — no OAuth, no human in the loop — with full send/receive functionality, inbound webhooks, and conversation threading per inbox.
The service runs on self-owned infrastructure rather than reselling capacity from a third-party provider.
The service runs on self-owned infrastructure rather than reselling capacity from a third-party provider. It uses KumoMTA for outbound mail delivery and Dovecot for IMAP, with dedicated mail servers. A built-in MCP server means agents running on Claude, ChatGPT, or any MCP-compatible LLM can connect natively without writing custom integration code. Pricing tiers are: 5 inboxes free, 100 inboxes for $29/mo, and 500 inboxes for $99/mo.
