What it is
An email API for transactional, marketing, notification and legal mail: sandboxed Jinja2 templates, bulk campaigns with suppression lists, full lifecycle webhooks, inbound handling and an MCP server so software agents can send email without glue code.
Who it is for. Product and platform teams that need one governed way to send and receive email across several tenants.

What it does
Sandboxed templates
Jinja2 templates rendered strictly: a missing variable blocks the send instead of going out blank.
Bulk campaigns
Campaigns with suppression lists, calendar compliance and real-time status tracking.
MCP server for agents
Software agents send email directly over the MCP protocol: one endpoint, no SDK.
Webhooks and lifecycle
Lifecycle webhooks signed with HMAC-SHA256, retried with exponential backoff, with delivery history.
Inbound email
Receive, retrieve and manage inbound mail with attachments and acknowledgement marking.
