オペレーション
A body authored once and sent many times, scoped to the workspace rather than to whoever wrote it.
Two engines, for two different people. blocks is a validated tree whose node kinds are the exports of @react-email/components, checked at its input and rendered here. html is markup you rendered yourself (a react-email component run through @react-email/render in your own build, a design-tool export, a hand-written table layout), sanitised once when the version is published. We cannot execute your JSX: workerd has no eval and no transpiler, so the render happens where the component lives and what crosses the wire is HTML.
Versions are immutable once published, and that is the feature rather than bookkeeping. Editing a published template mints a new draft; live sends keep resolving the frozen version until somebody publishes again. Without it, renaming a slot in the editor would silently start sending mail with a blank where the order number was: no error, nothing in a log, and no way to recall it. With it, the published version keeps saying orderId and the caller finds out from a 422 on their own schedule.
POST /emails also takes a template field, so a caller already composing a message need not switch endpoints to reach a stored body.
GET/templates
List templates
Each row carries the PUBLISHED version's subject, engine, slots and props, so a caller can see what to pass a template without a request per row. A template with nothing published carries none of them and reports publishedVersion: null.
Requires the templates:read scope.

POST/templates
Create a template
Creates the template and its version 1. publish: true freezes that version there and then; without it you get a DRAFT, and a draft is not sendable. POST /templates/{id}/send answers template_not_published until somebody publishes it.
The engine follows what you send: html when you post html, blocks otherwise, and engine is only worth stating to be explicit about it. document, slots and props are unconstrained in this schema on purpose. One validator owns the block tree so that REST, tRPC and MCP cannot each hold a slightly different copy of it, and a bad node comes back as a 422 naming its path rather than as a schema error here.
Requires the templates:write scope.

GET/templates/fonts
List the web fonts a template can load
A template loads a web font by naming a family and the url it is served from, and 17 families are accepted: DM Sans, Inter, Roboto, Open Sans, Lato, Montserrat, Poppins, Nunito, Work Sans, Source Sans 3, IBM Plex Sans, Merriweather, Playfair Display, Instrument Serif, JetBrains Mono, DM Mono, Geist Mono. This is that list, with the exact url each one takes.
The list is closed on purpose. A font file is fetched by the reader's mail client the moment the message is opened, so a url pointing anywhere else would report opens to whoever runs that host, silently and regardless of what the workspace has open tracking set to. A webFont.url that is not the one this endpoint gives for its family is a 422 invalid_template naming the font.
One template may load 8 of them. A font whose family is not here still renders: leave webFont out and the family falls back to fallbackFontFamily, which is what Gmail and Outlook on Windows do with every web font anyway.
Static, not workspace data, so the same answer comes back for every key.
Requires the templates:read scope.

The 17 fonts, in the order the console offers them.

List the starter designs
The same catalogue the console offers when somebody starts a template, so an integration and a person begin from the same designs rather than from two divergent lists.
Not paginated and not workspace data: these ship with the product. The slug is what POST /templates takes as starter and what POST /templates/{id}/content takes to re-skin an existing template. Bodies and previews are on the single retrieval, because twenty rendered emails is not a list payload.
Requires the templates:read scope.

POST/templates/render
Render a body that is not stored
Compiles content you pass in and hands back what a message built from it would carry. No template is created, none is read, and nothing is sent. It is what the web editor calls while somebody types, and the way to check a design in CI before it becomes a template at all.
It takes exactly what a create takes as content, plus values for the placeholders. Lenient like a preview: an unfilled key comes back in warnings rather than refusing, because a body being rendered is usually a body being written. mark: true leaves every placeholder as {{key}}, which is how an editor shows an author what is a variable.
Needs only templates:read, since nothing is written, and it is the one templates path that names no template.

PATCH/templates/{id}
Update a template
Metadata (name, description, status) changes the template in place. Anything touching the body (subject, document, html, slots, props, engine) writes into the DRAFT, and mints version N+1 when the head is already published. Nothing here changes what a live send resolves to: that only moves when somebody publishes.
expectedVersion is the version you read before editing. Supply it and a concurrent edit is a 409 instead of a silent overwrite, which is what an automated writer wants; omit it and the last write wins, which is fine for one person in one tab.

POST/templates/{id}/duplicate
Copy a template
Creates a separate template from the HEAD of this one: same subject, body, slots, props and description, at version 1 and always a DRAFT, whatever the source had published. A copy is therefore never sendable by accident.
Nothing links the copy to the source afterwards, which is what makes this the safe way to try a redesign of a template that is sending in production.
name is optional. Left out, the source name is reused, and since a name is unique per workspace the server appends a number until one is free, up to twenty. A name you send that is taken is treated the same way, so a nightly copy keeps working rather than failing on the second run.

POST/templates/{id}/content
Replace the design
Swaps the whole body for a starter design or for another template's, keeping this template's identity: the id, slug, name, description and status do not move, and neither does what a live send resolves to.
The write lands where a body edit lands. A draft head is overwritten in place; a published head mints version N+1 as a draft. Sends keep using the published version until somebody publishes, which is what makes this safe to call on a template that is sending.
Name exactly one source. starter takes a slug from GET /templates/starters; fromTemplateId takes another template in this workspace, whose published version is copied when it has one and whose draft is copied otherwise. A source in another workspace is a 404 like anything else, and the template naming itself is a 422.
The new body brings the source's slots and props with it and replaces the declarations wholesale, so a send that passed the old props can start being refused. Read the response before publishing.

POST/templates/{id}/versions
Publish the draft
A POST to the version COLLECTION, because that is what it creates: a frozen revision that live sends resolve against. Compiling happens here, so a template that does not render fails for the person publishing it rather than for the recipient of the next message.
Idempotent: publishing an already-published head returns it unchanged, so a deploy script that publishes unconditionally is safe to run twice.

GET/templates/{id}/versions/{version}
Retrieve one version
One frozen revision with its body: document for the blocks engine, html for the html engine, plus the subject, slots and props that were declared at the time.
This is what the version LIST leaves out, and it is the only way to see what an old version holds without changing anything. Restoring used to be the only route to that, and a restore moves the head, so reading version 3 cost you your draft. It does not any more.
Use it to diff a regression against the revision that worked, to copy a block out of an older design, or to archive what a campaign actually said. POST /templates/{id}/versions/{version}/restore is still the call that brings it back.

DELETE/templates/{id}/versions/{version}
Delete one version
Removes one revision and leaves the template alone. It is for tidying a long version list, not for changing what sends.
Three versions are refused, each as a 422 rather than a quiet success: the LIVE one, because sends resolve it; the HEAD, because that is the draft being edited, and restoring an older version first is how you move off it; and the only version a template has, because a template with no versions could not be read, so delete the template instead.
Mail already sent is untouched, since a send stores what it rendered. A send that pins a deleted version starts failing with template_version_not_found, and the number is never reused.

POST/templates/{id}/versions/{version}/restore
Restore an older version
Copies an older version's subject, body, slots and props forward into the head, which is how a design you regret is undone. Nothing is rolled back in place: the old version stays in the list and the restored copy becomes the current draft.
A published head mints version N+1; a draft head is overwritten, so restoring twice does not pile up versions. It does not publish, so live sends do not move until you do, and the restore is itself reversible until then.
Restoring the head is a 422 rather than a no-op, because it would silently do nothing. expectedVersion guards against a concurrent editor exactly as it does on a PATCH.

POST/templates/{id}/preview
Render without sending
The endpoint to point CI at. It resolves a version, substitutes the values and hands back exactly what a send would put in the message, so a template change is caught by a test rather than by a customer.
Lenient where a send is strict: a missing required prop comes back in warnings rather than refusing, because a template being previewed is usually a template being written. A send gets no such leniency. version may name a DRAFT here, which is the other thing a send cannot do.

GET/templates/{id}/analytics
How a template has performed
The report the console shows on a template: how much it sent, how much of that was tracked, how much was opened and clicked, and the same figures by day, by source and by version.
Rates are computed over what was TRACKED rather than over everything sent, because a message sent with tracking off can never report an open and counting it would quietly lower every rate. Both denominators are in the response so nothing has to be taken on trust.
lifetime ignores the window: every live send ever, the test-key sends counted separately, and the first and last time it sent. A template that has never sent answers with zeroes rather than a 404; the 404 is for a template that does not exist.

total counts the rows matching the filters rather than the page, which is what a table needs. Page numbers are not stable while mail is going out, since a new send pushes rows down: narrow the window rather than paging deep.

POST/templates/{id}/send
Send with a template
Resolves the published version (or the one version pins), substitutes props and slots, and sends. subject overrides the version's own for this message only.
Props are validated STRICTLY, which is the opposite of the preview: an unknown key is refused rather than ignored, and a declared required key that is missing is refused rather than rendered as a blank. Mail cannot be recalled, and a hole where the order number should be is not something a recipient can report back to you.
Also requires emails:send, and neither scope is redundant: reaching a stored body is templates:write, mail leaving the workspace is emails:send. A key that may send its own bodies still cannot send somebody else's template.
POST /emails takes a template field that does the same thing, for a caller already composing a message.

A designer applies written instructions to the block template and leaves everything else alone: restyle it, rewrite or translate its copy, add, move or remove sections. The change lands in the draft, and live sends keep the published version until it is published. It spends one AI action.
Requires the templates:write scope.

Trackingobject
Every /tracking endpoint returns this whole, its list included. It arrives trimmed in exactly one place, under tracking on a GET /emails row, where it is the counts half only: opens, clicks, opened, clicked, openCount, clickCount and firstOpenAt. A page of fifty sends each carrying its recipients and its links is a report nobody asked to have expanded. The trimmed form has no id on it either, so /emails/{id}/tracking rather than /tracking/{id} is the way back to the rest of it.

date-time opensbooleanWhat was APPLIED to this message, resolved when it was sent from the setting of the address it was sent from (its own, else its domain catch-all's, else off, while a broadcast copy is on unless the broadcast or its address turned it off) and any per-send override, not what is switched on now. Turning tracking on today does not make yesterday's mail start reporting, and a report that implied otherwise would read as "nobody opened it".
clicksbooleanAs
opens, for link rewriting. The two are independent switches.openedbooleanclickedbooleanattributablebooleanWhether every reading on this message can be pinned to a named recipient. False as soon as an unattributed copy has activity of its own, which is what happens whenever one body went to the whole list rather than a separate one per person. This is the flag that decides whether "Bob has not opened it" is a sentence a client is entitled to write, or whether all it may say is that somebody did.
recipientscarries the same fact one row at a time, and one row at a time is where it gets missed.openCountintegerOpens that looked like a person, with repeat fetches within thirty seconds collapsed. A preview pane redrawing is not a second reading. Through Gmail this is a floor and not a total: its proxy fetches the image once and caches it, so later readings never reach us.
clickCountintegerCounted clicks. Stronger evidence than an open, and worth weighting as such: images are blocked far more often than links go unfollowed, so a message with clicks and no opens was certainly read.
openCountRawintegerEvery open hit, the automated ones included.
openCountRaw - openCountis everything that was filtered out: Apple Mail Privacy Protection and corporate link scanners, which fetch on delivery whether or not a person ever looks, and alongside them the repeat fetches collapsed by the thirty-second window. Both are recorded and neither is counted, because discarding them outright would leave a gap in the log that nothing could explain. Do not read the difference as a machine count on its own.
