How is Dead Simple different from AgentMail or other agent email APIs?
“Three things. First, a real dashboard on every plan including Free; most agent email APIs are API-only, so you can't see what your agent actually did.”
Dead Simple Email
“Email API built for AI agents. 100 inboxes for $29/mo. Webhooks on all plans. Dashboard included.”
Questions & answers
Can my agent sign in to other apps with its inbox?
“Yes. Sign in with Dead Simple is a free OpenID Connect provider at https://id.deadsimple.email where the identity is the agent's inbox.”
Can my agent use the API without an account or API key?
“Yes. Call a priced route with no credentials and it answers HTTP 402 with a price.”
Why is Dead Simple so much cheaper?
“We operate our own deliverability stack and pass the efficiency on as lower pricing, with direct control over inbox placement instead of paying a third-party markup.”
Can my agent receive emails?
“Yes. Dead Simple is fully bidirectional. Inbound emails arrive as structured JSON via real-time webhooks with HMAC signing. You also get automatic threading, reply parsing, and conversation history through the API. Every inbox also includes standard IMAP/SMTP credentials for direct access.”
Can I connect via IMAP or SMTP instead of the API?
“Yes. Every inbox comes with standard IMAP and SMTP credentials. Connect with any email client, use imaplib, or plug into legacy tools. IMAP runs on port 993 (SSL/TLS) and SMTP submission on port 587 (STARTTLS) at mail.deadsimple.email. Use the REST API, IMAP/SMTP, or both.”
What is Dead Simple Email?
“Dead Simple Email (DSE) is an email API and dashboard built for AI agents. It lets software programs send and receive email through dedicated inboxes, managed via API or dashboard. It is not a marketing platform, a Gmail replacement, or an AI product itself — it's infrastructure for AI agents that need email.”
Who is Dead Simple Email for?
“Developers and teams building AI agents that send or receive email. This includes AI sales agents, support agents, scheduling assistants, recruiters, and any autonomous software that needs a real email inbox. It is also used by AI development agencies building agents for clients.”
Does Dead Simple Email support MCP (Model Context Protocol)?
“Yes. DSE has a native MCP server. Any AI agent built with Claude, ChatGPT, Hermes Agent, LangChain, CrewAI, AutoGen, OpenClaw, or any other MCP-compatible framework can connect to DSE email without writing custom integration code.”
Does Dead Simple Email support webhooks?
“Yes, on all plans including the free tier. Webhooks let your agent receive a real-time notification the second a new email arrives, instead of polling the API. Every inbox can have its own webhook URL.”
Can my agent keep a calendar and handle meeting invitations?
“Yes. Every inbox has a calendar on every plan.”
