メソッド
Send mail now or later, in batches or translated, and follow what happened to it.
Emails.Send
Send, schedule or translate and send one email
Send(ctx context.Context, body openemail.Body, opts ...openemail.RequestOption) (openemail.Object, error)Sends one message now, or holds it for later with scheduledAt or an undo window with cancellableForSeconds. The body comes from exactly one source: html and or text, a stored template, or an existing draftId. Naming none is a 422, and template alongside html, text or draftId is refused. An immediate send is dispatched inside the request, so the call usually returns a sent, partial or failed message. A held send settles as queued or scheduled, so read status rather than treating a returned message as delivered mail.
Every call carries an Idempotency-Key. The SDK generates one per call and reuses it on that call's retries, and the API claims it against the key's own unique index before anything is dispatched, so a retried network failure replays the original message instead of sending a second one. Pass openemail.WithIdempotencyKey to extend that across processes and restarts, deriving it from what made the send necessary rather than from a clock. A replay returns replayed: true and the stored message in its current state. The same key with a different body is a 422 idempotency_key_reuse.
Add translate to deliver the message in the recipient's language. The translation runs when the request is accepted, before any record exists, so a scheduled send carries the approved wording and a translation that cannot be produced refuses the whole send: nothing is ever delivered untranslated as a fallback. By default the subject is translated too and your original text is placed below the translation, captioned in the target language. It works with template, translating what the template rendered, and is refused alongside draftId because a draft goes as it was written.

戻り値
An openemail.Object, an email object plus replayed. Notable fields are id (msg_ plus 24 hex), status, mode, from, subject, scheduledAt, cancellableUntil, sentAt, lastError, tags, stream and, on a translated send, translation.
例

A message sent with
streamset tobroadcastwhile that lane is paused for too many bounces or complaints is refused with 409stream_paused.Sending.ListStreamsshows why, and app mail on thetransactionallane still goes.A
fromon a domain that is known to the workspace but cannot sign mail yet is refused up front with 409domain_not_sendableandparamset tofrom, so nothing is accepted that would only fail at dispatch.Addresses.Listshows the same verdict ascanSendbefore you send.A test key (
oe_test_) never delivers. The message is markedsentwithtransportset totestand every recipientdelivered, so assert on the response and not on an inbox.The idempotency fingerprint covers the template version the send resolved to. Retrying an unpinned template send after somebody publishes a new version is a 422
idempotency_key_reuse, not a replay.scheduledAtis left out of the fingerprint.A spent send allowance is a 429
send_quota_exceededwith noRetry-After, and it resets on the first of the month. The SDK does not retry a 429 that carries noRetry-After, so the call fails straight away.Translation failures refuse the send: 409
translation_not_configuredwhen the workspace has no AI, 422translation_too_longpast 30,000 characters, 429ai_quota_exceededwhen the workspace has used today's AI actions, and 503translation_failedwhen the provider did not answer.A translated send spends one AI action.
openemail.ErrRetryableis true for every 429, butai_quota_exceededfails the same way until the allowance resets at midnight UTC, so show it to a person or send withouttranslate.A
followUpAtthat is not later than the time the message goes out, or is more than 365 days out, refuses the send with a 422 whoseparamisfollowUpAt, codedinvalid_follow_uporinvalid_parameter, and nothing is sent. Atime.Timeis sent as an ISO 8601 instant, as it does forscheduledAt.

Emails.SendBatch
Send up to 100 independent emails in one request
SendBatch(ctx context.Context, emails []openemail.Body, opts ...openemail.RequestOption) (*openemail.BatchResult, error)Sends each message in order, as if Emails.Send had been called for it, and reports per item. It is never all or nothing: a bad address on item 7 fails item 7 and the rest still go, because a batch that rolled back would turn your retry into a guess about which messages had already been delivered. The call returns whenever the batch was processed, so check Failed and each item's status rather than relying on an error.
The batch shares one Idempotency-Key, generated once per call or supplied as openemail.WithIdempotencyKey, and the server derives a separate key per item from it and the item's position. Retrying the same list replays the items that already went and sends only the ones that did not. Reordering the list between attempts changes which body each position's key is bound to, so an item that moved comes back as an idempotency_key_reuse error.
Apart from a key or scope failure or a server fault, only problems with the batch as a whole fail the call with a 422: an empty list, more than 100 messages, or more than 10 messages carrying translate. Translation costs several model calls per message and they run one after another, so a larger translated batch would time out partway. Split it, or schedule the messages instead.
パラメーター
emails[]openemail.Body必須Between 1 and 100 messages, each shaped exactly like the body of
Emails.Send,followUpAtincluded, and validated on its own.openemail.WithIdempotencyKeystringYour own batch key, 1 to 255 characters of letters, digits,
_,.,:or-.openemail.WithAPIKeystringSends the batch with this key instead of the client's.
戻り値
An *openemail.BatchResult with Sent, Failed and Items. Each item has its index and either status set to ok with the email, shaped like what Send returns, or status set to error with an error carrying type, code, message and, when a field is to blame, param.
例
result, err := client.Emails.SendBatch(ctx, []openemail.Body{ { "from": "[email protected]", "to": "[email protected]", "subject": "Order AC-4192 has shipped", "text": "It is on its way.", }, { "from": "[email protected]", "to": "[email protected]", "subject": "Order AC-4193 has shipped", "text": "It is on its way.", },}, openemail.WithIdempotencyKey("shipments:2026-09-15"))if err != nil { return err} fmt.Println(result.Sent, "sent,", result.Failed, "failed") for _, item := range result.Items { if item.String("status") == "error" { failure := item.Object("error") fmt.Println("Item", item.Int("index"), failure.String("code"), failure.String("message")) }}注意事項
Each entry is authorised on its own, so a
fromon a domain that cannot sign yet fails that entry withdomain_not_sendablewhile the rest go.Once the send allowance of the workspace runs out partway, every remaining item fails with
send_quota_exceededwhile the earlier ones stay sent. It is counted for that workspace alone, so sends from other workspaces never spend it. A workspace on a paid plan with pay as you go turned on keeps sending past it instead.Each item with
translatespends one AI action. Once that account has used today's AI actions, every remaining item withtranslatefails withai_quota_exceededwhile items without it still go. Retrying those items fails the same way until the allowance resets at midnight UTC, unless the account has pay as you go turned on.An unexpected server fault aborts the batch with a 500 after the earlier items have gone. The SDK retries it with the same key, which replays those items instead of sending them twice.
Items are processed one after another inside a single request, so a large batch of immediate sends takes noticeably longer than one
Send. Keep the client timeout generous.

Emails.Translate
Preview a translation without sending anything
Translate(ctx context.Context, body openemail.Body, opts ...openemail.RequestOption) (openemail.Object, error)Runs the same translation translate performs on a send and stops one step early. The same function produces both, so what comes back is what would go out. Nothing is stored and nothing is sent. Use it when somebody should read the translated wording before it reaches a recipient.
Send the approved result as an ordinary subject and html on Emails.Send with no translate option. Passing translate again translates a second time, moving the wording off the version that was signed off and discarding any edits. When includeOriginal is on, html already contains your original text below the translation, so do not append your own copy.
At least one of html, text or subject is required. to accepts a BCP-47 code, an English name or the language's own name, and the response reports the code it settled on in language.code, which is the form worth storing. State from to skip language detection. Otherwise it is detected from the body, and a detector that cannot tell returns null in detectedSourceLanguage rather than guessing.
パラメーター
tostring必須Target language as a code (
de), English name (German) or endonym (Deutsch). An unrecognised value is a 422invalid_parameteronto.fromstringThe language you wrote in. Stating it skips the detection call.
includeOriginalboolDefaults to true, placing your original text below the translation under a caption in the target language.
subjectstringSubject line to translate, at most 998 characters.
htmlstringHTML body to translate. Only the content inside
<body>is sent to the model when the markup is a full document.textstringPlain text body to translate. Translated separately when given alongside
html.openemail.WithAPIKeystringRuns the preview with this key instead of the client's.
戻り値
An openemail.Object with object set to translation, language and detectedSourceLanguage as full language object rows, subject, html and text (each null when that input was not given) and includeOriginal.
例
preview, err := client.Emails.Translate(ctx, openemail.Body{ "to": "ja", "subject": "Your September invoice", "html": "<p>The invoice is attached.</p>",})if err != nil { return err} fmt.Println(preview.Object("language").String("native"), preview.Object("detectedSourceLanguage").String("code"), preview.String("subject"), preview.String("html"))注意事項
The SDK never retries this call. Each attempt spends one AI action, as a translated send does. Handle a 503
translation_failedyourself, and treat a 429ai_quota_exceededas final until the allowance resets at midnight UTC.Anything over 30,000 characters is refused with 422
translation_too_longrather than truncated, since half a translation has no seam to show where it stopped.A right-to-left target comes back with
htmlwrapped indir="rtl".A workspace with no AI configured gets 409
translation_not_configured, and retrying will fail the same way.

Emails.Check
Check how a message would be rated, without sending it
Check(ctx context.Context, body openemail.Body, opts ...openemail.RequestOption) (openemail.Object, error)Scores a message the way a receiving mailbox would, before it goes out: a spam score, a phishing score and an AI-writing score, each 0 to 100, with the signals behind each one. Nothing is stored and nothing is sent.
The same checks score every message that arrives in an OpenEmail mailbox, so what comes back is what an OpenEmail recipient sees in Details. It cannot know a recipient's own filter, sender history or reputation, so a low score is a good sign and not a delivery guarantee.
Run it before an automated send, or as someone writes, and fix what signals names. Sender authentication is taken as passing, since the message will be signed for your domain.
パラメーター

openemail.WithAPIKeystringRuns the check with this key instead of the client's.
戻り値
An openemail.Object with object set to email_check and three scores. spam carries score, level (low, medium from 35, high from 60) and signals. phishing carries score, level (clear, caution from 30, danger from 60), signals and reasons. ai carries score (null when not judged), level, signals, reasons, words and skipped (too-short under 40 words).
例
check, err := client.Emails.Check(ctx, openemail.Body{ "from": "[email protected]", "subject": "Your September invoice", "html": "<p>The invoice is attached.</p>",})if err != nil { return err} fmt.Println(check.Object("spam").String("level"), check.Object("spam").Int("score"), check.Object("phishing").Int("score"), check.Object("ai").Int("score"))注意事項
It spends no AI action and never calls a model, so it is safe to run on every revision.
A score is not a probability. Each one adds up weighted signals, heaviest first in
signals.

Emails.List
List one page of sent emails, newest first
List(ctx context.Context, opts ...openemail.RequestOption) (*openemail.Page, error)Returns one page of the workspace's send records, ordered newest first. Paging is keyset rather than offset: NextCursor is the id of the last message on the page, and passing it back as cursor continues strictly after it, so messages sent while you page never shift or repeat rows. HasMore is false on the last page and NextCursor is then null.
Filter with status, one value or an array that the SDK joins with commas, with from, which matches the sending address exactly and ignores case, with broadcastId, which keeps the copies of one broadcast, and with scheduledFrom and scheduledTo, which keep the messages scheduled inside a window. An unrecognised status is a 422 invalid_parameter naming the offending values, and a cursor that names no message in the workspace is a 400 invalid_cursor.
Rows are the summary form. They never carry recipients or translation, whose absence on a row says nothing either way, and a tracked message carries only the counts half of tracking: opens, clicks, opened, clicked, openCount, clickCount and firstOpenAt. Call Get for per-recipient delivery state and GetTracking for the full engagement report.

戻り値
A *openemail.Page with Items, HasMore and NextCursor. Each item has id, status, mode, from, subject, transport, attempts, lastError, scheduledAt, cancellableUntil, sentAt, tags, broadcastId, source, createdAt and, when tracked, the trimmed tracking counts.
例

Emails.ListAll
Collect every matching sent email into one slice
ListAll(ctx context.Context, opts ...openemail.RequestOption) ([]openemail.Object, error)Follows NextCursor from page to page and returns once the last page has been read, with every matching send record in one slice, newest first. It accepts the same filters as List and returns the same summary rows, so there are no recipients or translation on them and tracking is the trimmed counts form.
Everything is held in memory before the call returns, and a workspace's send history grows without bound. Narrow it with status or from, or switch to Iterate when you want to stop early or process rows as they arrive. limit sets the page size of each underlying request, not the total, so a larger value means fewer round trips.

Emails.Iterate
Stream sent emails one at a time across pages
Iterate(ctx context.Context, opts ...openemail.RequestOption) *openemail.IteratorReturns an iterator that yields send records individually, newest first, and requests the next page only once the current one is drained. Nothing is fetched until you start consuming it, and breaking out of the loop stops the requests, so this is the cheapest way to find the most recent message matching a condition the filters cannot express.
The walk is keyset based, following NextCursor from page to page. Mail sent while you iterate lands ahead of where you started and is never yielded, and nothing already yielded comes round again. Rows are the same summary form List returns.

Emails.Get
Read one sent email with per-recipient state
Get(ctx context.Context, id string, opts ...openemail.RequestOption) (openemail.Object, error)Returns the full send record for one message: its lifecycle status, delivery attempts and lastError, the schedule fields, and the two parts a list row leaves out. recipients has one entry per address with its own status, error and deliveredAt, and translation records what was done to a translated send.
A message that went out as a single call can still land differently per recipient. status on the message says how the send went as a whole, while each recipient moves on as delivery reports, bounces and complaints arrive. uncertain is a real recipient state: a transport that failed partway cannot say which recipients it reached. suppressed marks an address that previously bounced or complained in this workspace and was held back.
When the message was tracked, tracking carries the full engagement report with per-recipient and per-link detail. When it was not tracked, the field is absent rather than zeroed, because a message with no pixel has no evidence about whether anybody read it.

Do not correlate on
messageId. The header is rewritten on the way out, so that value appears in no bounce or delivery report. Webhook events name the send by thisid, asemailId.A 404 never distinguishes a missing id from one in another workspace, and a narrowed key gets the same 404 for a message sent from an address it does not cover.
transportstays null until dispatch, and readsteston every message sent with a test key.

Emails.ListEvents
Read one page of the event trail of one sent email
ListEvents(ctx context.Context, id string, opts ...openemail.RequestOption) (*openemail.Page, error)Returns one page of everything recorded against one send, oldest first. Nothing is dropped from the trail, so following NextCursor while HasMore is true reaches its newest event, and ListAllEvents and IterateEvents do that walk for you. It is the audit behind the current status: when the message was accepted or held, when it was rescheduled or cancelled, when it went out or failed, and every delivery report, bounce, complaint, open, click and file download attributed to it afterwards.
Each event has a dotted type and a data object whose shape depends on it. email.accepted, email.queued and email.scheduled open the trail with the source and recipient count. email.sent names the transport and messageId. email.failed carries the error. email.bounced and email.complained list the affected recipients and whether they were suppressed. email.delivered, email.rescheduled, email.cancelled, email.opened, email.clicked and email.downloaded follow as they happen. email.downloaded counts a person fetching a file that went out as a download link, never a scanner, and carries no recipient: the link is the same for everyone the message went to, so a download cannot be attributed. data is an empty object when an event carries nothing.
Webhooks deliver a subset of these same events as they occur, so this is where to look when a webhook was missed or never subscribed.

email.deliveredis recorded in this trail but is never sent as a webhook, so a delivery report surfaces only here and inrecipientsonGet.A send made with a test key records
email.sentwithtransport: 'test'andsimulated: trueindata.An unknown id is a 404, never an empty page.
A tracked message opened or clicked many times records one event per counted hit, so its trail can run to many pages.

Emails.ListAllEvents
Collect the whole event trail of one sent email into one slice
ListAllEvents(ctx context.Context, id string, opts ...openemail.RequestOption) ([]openemail.Object, error)Walks every page of one send's event trail and returns with all of it, oldest first: acceptance, scheduling, sending, every delivery report, bounce and complaint, and every counted open, click and download afterwards.
A widely read message can hold a great many events, all in memory before the call returns. Prefer IterateEvents when you can stop early. limit sets the page size of each request, not the total.

A failure on any page fails the whole call, and the events already fetched are discarded.

Emails.IterateEvents
Stream the event trail of one sent email one event at a time
IterateEvents(ctx context.Context, id string, opts ...openemail.RequestOption) *openemail.IteratorReturns an iterator over one send's event trail that yields events individually, oldest first, and fetches the next page only when the current one is drained. Nothing is requested until you consume it, and breaking out of the loop stops further requests.
The walk moves forward in time, so events recorded while you iterate are yielded when the walk reaches them, and it ends when HasMore is false.

The iterator is lazy, so an abandoned loop costs only the pages you consumed.

Emails.GetTracking
Read the engagement report for a sent email
GetTracking(ctx context.Context, id string, opts ...openemail.RequestOption) (openemail.Object, error)Returns the same document Tracking.Get serves, reached from the msg_ id a sender already holds. It has the message totals, one entry per tracked copy under recipients, and every rewritten link with its clicks under links.
A message that was never tracked is a 404 here rather than an empty report. "We were not recording" and "nobody opened it" are different answers, and a client that renders them the same way makes a claim about a reader on no evidence. Tracking applies per send: opens and clicks record what was applied when the message went out, resolved from the setting of the address it was sent from (its own, else its domain catch-all's when the catch-all caught that address, else off) and any tracking override on the send, not what is switched on now.
Read every count as a floor. An open is inferred from a mail client fetching an image, so a reader whose client blocks images is never counted, and Gmail fetches the image once through its proxy and serves later views from cache. A click is stronger evidence than an open.

Only claim a named recipient has not opened when
attributableis true. Mail that went to the whole list as one body has a shared copy whoseemailis null, and its opens cannot be pinned to anybody.A message sent with a test key is never tracked, so this is always a 404 for one.
openCountRaw - openCountincludes machine fetches such as Apple Mail Privacy Protection and repeats within thirty seconds, so do not read the difference as a pure machine count.

Emails.Cancel
Stop a queued or scheduled email before it goes
Cancel(ctx context.Context, id string, opts ...openemail.RequestOption) (openemail.Object, error)Cancels a message that has not been dispatched yet: a send held by scheduledAt, or an immediate send still inside its cancellableForSeconds undo window. The message moves to cancelled, nothing is delivered, and an email.cancelled event is recorded and sent to subscribed webhooks.
Only queued and scheduled messages can be cancelled. Once a message is sending, sent, partial, bounced or failed the call is a 409 email_not_cancellable, since there is no pending dispatch left to stop and mail that has gone cannot be recalled. An immediate send with no undo window is dispatched inside the Send request, so by the time you hold its id it is usually past this point.
Cancelling is idempotent. Cancelling an already cancelled message returns the same cancelled message rather than an error, and the SDK retries the call after a network failure or a retryable status.
パラメーター
idstring必須The
msg_send id to cancel.openemail.WithAPIKeystringCancels with this key instead of the client's.

cancellableUntilon the message is the moment it stops being cancellable. Past it, expect the 409.A cancelled message stays cancelled. There is no way to resume it, so send again if you change your mind.
A narrowed key gets a 404 for a message sent from an address it does not cover.

Emails.Reschedule
Move a queued or scheduled email to a new send time
Reschedule(ctx context.Context, id string, scheduledAt time.Time, opts ...openemail.RequestOption) (openemail.Object, error)Changes when a message that has not gone yet will be dispatched. scheduledAt is the only thing this call can change, and the SDK sends nothing else: the body, recipients and any translation stay exactly as they were accepted.
The new time takes a time.Time, an ISO 8601 instant or a duration such as PT30M or P2D, measured from when the server receives the request. It must be at least one second in the future and at most 365 days out, otherwise the call is a 422 on scheduledAt, usually invalid_parameter. Earlier and later times are both allowed.
Only queued and scheduled messages can be moved. Anything already sending, sent, partial, bounced, cancelled or failed is a 409 email_not_cancellable. A queued message inside its undo window can be rescheduled too, which turns it into a scheduled send that stays cancellable until the new time.

The SDK retries this call after a network failure. A duration is resolved again on each attempt, so a retried
PT1Hlands an hour after the last attempt the server received.An
email.rescheduledevent with the newscheduledAtis added to the trail on every successful move.A translated scheduled message keeps its approved wording. To change the text itself, cancel it and send again.

Emails.Update
Change an email that has not gone yet
Update(ctx context.Context, id string, patch openemail.Body, opts ...openemail.RequestOption) (openemail.Object, error)Changes a queued or scheduled message before it is dispatched: when it goes with scheduledAt, what it says with subject, html and text, the address it goes out as with from, and who it goes to with to, cc and bcc. Send any of them together, and a field you leave out keeps its value. This is what editing a scheduled message in the calendar of the app does.
A recipient list replaces the stored one whole, and takes a string such as Ada <[email protected]>, an object with email and name, or an array of either. from is checked as it is on a send, so it has to be an address the key may send as, or the call is a 403 from_address_forbidden.
Only messages that have not gone can change. Anything already sending, sent, partial, bounced, cancelled or failed is a 409 email_not_cancellable. A message translated when it was accepted keeps its approved wording, so a new subject, html or text on it is a 409 translation_locked, and one that was encrypted before it was scheduled keeps its wording and its recipients. Cancel those and send again instead.

Emails.Compose
Write an email with AI
Compose(ctx context.Context, body openemail.Body, opts ...openemail.RequestOption) (openemail.Object, error)Writes the body of an email from prompt, an instruction, a rough draft or a few notes, in the style of the mail this workspace has sent before, as the composer of the app does. subject, to and cc help the greeting and the tone fit, and from, the address it goes out as, has it written as that address.
Give threadId to write a reply: the messages of that thread are read as context, which also needs threads:read, and a key limited to particular addresses can only use a thread that arrived at them.
Give draft, the body written so far, and prompt says what to change in it, as the describe bar of the composer does. withSubject: true adds subject to the answer. Give Send, the send options as they stand, even an empty map, and prompt may change the recipients, the send time, tracking, the signature and the language: the answer's Send holds only what changed, in the shape Emails.Send takes, and null takes an option away. Add send.fromOptions, the addresses it may go out as, and prompt may move it to one of them, which the answer names in send.from. Add send.encrypt, whether it is encrypted end to end as it stands, only when every recipient can receive encrypted mail, and prompt may turn encryption on or off. Times such as "tomorrow at 9" are read in timeZone, or the time zone of the account.
Give templates: true and prompt may switch the email to one of the workspace's published templates, which the answer names in template: pass template: { id: template.id } to Emails.Send in place of body, because the template's body replaces it. Give template, the id of the template the email uses now, and prompt leaves the body alone. Give files: true and prompt may attach files the workspace holds, found by their name: the answer lists them in attach, each ready to pass to Emails.Send as a map with fileId set to id in attachments, and names in attachMissing what matched no file. templates needs templates:read and files needs files:read, and each is ignored without its scope. A key limited to particular addresses only finds the files at those addresses.
Nothing is saved or sent. Pass body to Emails.Send or Drafts.Create when it reads right. Each call spends one of the workspace's AI actions, and a workspace that has used them all for the day is refused with a 429 ai_quota_exceeded.

Rewrite part of an email with AI
Rewrite(ctx context.Context, body openemail.Body, opts ...openemail.RequestOption) (openemail.Object, error)Rewrites a subject or a body and returns different versions of it, as the rewrite menu of the composer does. action is shorten, lengthen, rephrase, formal, casual or custom, and custom needs instruction to say what to change, or the call is a 422 invalid_parameter on instruction. target is body, the default, or subject, and count asks for 1 to 5 versions, 3 by default.
