tinysend vs AgentMail
AgentMail is a purpose-built email inbox for AI agents — programmatic inboxes, threading, semantic search, IMAP/SMTP, SOC2, and real traction. If an agent inbox is all you need, it is excellent and goes deeper than we do on inbox tooling. tinysend covers agent email too — disposable inboxes, OTP extraction, an MCP server, and auth.md so an agent can register with no human at all — and adds newsletters, subscribers, and open/click tracking that AgentMail does not.
Honest both ways: AgentMail wins on raw inbox depth, tinysend wins on self-registration and the human side of email.
| capability | agentmail | tinysend |
|---|---|---|
| inbox for agents, send + receive | yes | yes |
| agent self-signup, no human (auth.md) | no — human provisions | yes |
| disposable inbox in one call | no | yes |
| MCP server | yes | yes |
| IMAP / SMTP access | yes | no |
| semantic inbox search | yes | no |
| SOC2 | yes | no |
| newsletters + subscribers | no | yes |
| open/click tracking | no | yes |
Pick AgentMail if you are building an agent that mainly needs a deep programmatic inbox — IMAP/SMTP, semantic search, SOC2 — and you do not need newsletters or audience tools.
Pick tinysend if you want an agent to register with no human in the loop (auth.md), or you want agent email alongside newsletters, subscribers, and tracking in one place.
They can be complementary: some use AgentMail for deep agent-inbox workflows and tinysend for sending, self-registration, and newsletters. See managing subscribers and custom domains.
