Broadcasts

Every operation in this group: what it accepts, what it returns and the errors it can answer with.

Operations

One message sent to everybody in one or more audiences, as a separate copy for each person, personalised from the contact with merge fields and carrying a one-click unsubscribe. The sending happens in the background: create the broadcast, then read it for its progress, and list its copies with GET /emails?broadcastId=.

Every copy carries the unsubscribe headers the large mailbox providers require of bulk mail, and a person who unsubscribes is skipped by every later broadcast to those audiences. The suppression list applies as it does to every send.

GET`/broadcasts`

List broadcasts

emails:readReads

Every broadcast in this workspace, newest first, one page at a time, each with live counts. audienceId keeps the ones that were sent to that audience, among others or alone.

The individual messages are not here. List them with GET /emails?broadcastId=.

A key limited to particular addresses or domains lists only the broadcasts sent from an address or domain it holds.

Requires the emails:read scope.

Query parameters

limitinteger: Rows per page, 1 to 100.
At least 1At most 100Default25
cursorstring: A broadcast id. Keyset, not offset: pass the previous page's nextCursor. One that names nothing in this list is a 400 invalid_cursor.
audienceIdstring: Only the broadcasts that included this audience. An id that names no audience answers an empty list rather than a 404.
1 to 64 characters

Returns

200BroadcastList

A page of broadcasts, newest first.

Errors

400: invalid_cursor when cursor names no broadcast in this workspace.
422: invalid_parameter on a limit out of range.

POST`/broadcasts`

Send to audiences

emails:sendaudiences:readSends mail

Honours Idempotency-Key

Sends one message to everybody in one or more audiences, as a separate copy for each person. Every copy has exactly one recipient and no cc or bcc, so nobody sees who else it went to, and every copy is an ordinary email with its own msg_ id, events, tracking and webhooks. GET /emails?broadcastId= lists them. Copies are not filed in the Sent folder: the broadcast is the record.

The call answers 202 straight away with the broadcast queued, or scheduled when scheduledAt is set, and the sending happens in the background, 50 people at a time. Read GET /broadcasts/{id} for status and counts as it goes.

WHO GETS IT. Every contact in at least one of audienceIds, counted once however many of them hold it, except a person who has unsubscribed (GET /suppressions/unsubscribes lists them), and except an address on the suppression list. A contact in one of excludeAudienceIds is left out too, even when they are in one of audienceIds. audienceIds cannot name All contacts, the built-in audience that holds everyone this workspace has ever written to, because most of those people never asked for its mail: that is a 422 audience_is_everyone, and a send to it that was scheduled before this rule fails when its time comes. A contact added to one of the audiences after this call but before the sending reaches it is included. counts.recipients is the estimate taken now, and POST /broadcasts/preview returns the same count without sending anything.

QUOTA. The whole send is checked against the plan's monthly sends before anything is written. A broadcast the allowance cannot cover is refused with 429 send_quota_exceeded and leaves nothing behind. Each copy counts as one send.

PERSONALISATION. subject, html and text take merge fields, filled in for each person: {{firstName}}, {{lastName}}, {{name}}, {{email}}, {{unsubscribeUrl}}. Each takes a fallback after a bar, such as {{firstName|there}}, used when the contact has no value for it. The values come from the contact: the first name is the first word of its name and the last name is the rest. A custom field of the contact is {{attributes.<key>}}, such as {{attributes.plan|Free}}, and reads as its fallback, or as nothing, when the contact has no such field. Every value is escaped in html, and any other {{…}} is left as written. With template, the five values above are passed as props, but only the props the template declares, except unsubscribeUrl, which every template receives.

UNSUBSCRIBE. Every copy carries List-Unsubscribe and List-Unsubscribe-Post: List-Unsubscribe=One-Click, which is what lets a mail client offer its own unsubscribe button and what the large mailbox providers require of bulk mail. A body or a template that does not place {{unsubscribeUrl}} itself gets a short footer with the link, in English, which also names the sender and shows the postal address once marketingPostalAddress is set on PATCH /settings. A template receives unsubscribeUrl whether it declares it or not, so one that places it decides where the link goes. The link opens a page with an Unsubscribe button, and following it unsubscribes the person from all of this workspace's marketing mail: every audience they are in shows unsubscribedAt on GET /audiences/{id}/contacts, they are listed on GET /suppressions/unsubscribes, and later broadcasts and automation emails skip them, even after they are added to an audience again or their contact is deleted and made again. Their contact and mail sent to them one message at a time are not affected.

LIMITS. 1 to 10 audiences and up to 8 tags, and every copy also carries the tag broadcast_id. No attachments, cc, bcc, translation or encryption. The body comes from html and or text, or from template, never both.

IDEMPOTENCY. Send an Idempotency-Key and a retry with the same key answers 200 with the broadcast the first call created, with replayed: true and Idempotency-Replayed: true, instead of sending again. The same key with a different body is a 422 idempotency_key_reuse. Without a key, sending the same body twice sends the broadcast twice.

Requires the emails:send and audiences:read scopes.

Request body

audienceIdsstring[]Required

1 to 10 audience ids. A contact in several of them gets one copy. Each id has to name an audience in this workspace, or nothing is sent.

1 to 10 items

excludeAudienceIdsstring[]

Up to 10 audiences whose members are left out, even when they are also in one of audienceIds, such as the customers who already bought. All contacts may be named here.

Up to 10 items

segmentIdstring

A saved segment that narrows the audiences: only the contacts that match its conditions get a copy, such as the people who opened in the last 90 days. The conditions are read when the broadcast is sent or scheduled and kept with it, so editing the segment later changes nothing that is already on its way. Resending to the people who did not open leaves the segment out, because they already passed it.

1 to 64 characters

fromstring | objectRequired

The sender, as on POST /emails: an address the key may send as, bare or with a name.

emailstringRequired: Up to 320 characters
namestring: Up to 128 characters

replyTostring | object

Where replies go, the same for every copy.

emailstringRequired: Up to 320 characters
namestring: Up to 128 characters

subjectstring

Required unless a template supplies it. Takes merge fields: {{firstName}}, {{lastName}}, {{name}}, {{email}}, {{unsubscribeUrl}}, and {{attributes.<key>}} for a custom field of the contact, each with an optional fallback after a bar, such as {{firstName|there}}.

Up to 998 charactersDefault""

htmlstring

The HTML body, with the same merge fields, their values escaped. Without {{unsubscribeUrl}} in it, a one-line unsubscribe footer is added.

Up to 1000000 characters

textstring

The plain text body, with the same merge fields. Without {{unsubscribeUrl}} in it, an unsubscribe line is added.

Up to 1000000 characters

templateobject

A stored template instead of html and text. The merge values are passed as props, but only the ones the template declares, except unsubscribeUrl, which every template receives. A template that does not place it gets the same footer as a body.

tagsRecord<string, string>

Up to 8 tags, copied onto every copy beside broadcast_id, which the server adds.

Default{}

utmobject

Campaign tags added to every http and https link in the body: source, medium, campaign, term and content become utm_source and the rest, so the visits show up in your web analytics. A link that already carries one keeps its own value, and the unsubscribe link never gets them. Values are 1 to 100 characters, campaign up to 200.

mediumstring: 1 to 100 characters

abTestobject

An A/B test. variants holds 2 to 4 versions, each a subject, or a body as html and or text, that replaces the broadcast's own, so {} keeps the broadcast as it is. testPercent (5 to 50, 20 unless set) of the people get a variant, split evenly between them, and metric (opens unless set, or clicks) picks the winner once waitMinutes (30 to 4320, 240 unless set) have passed since the test went out. Everybody else then gets the winning variant. The rate counts the people who opened or clicked out of the copies each variant sent, a tie goes to the earlier variant, and with nothing to compare the first variant wins. A template broadcast can only vary the subject.

POST`/broadcasts/preview`

Count who a broadcast would reach

audiences:readReads

The numbers POST /broadcasts would work from, without sending anything or writing anything: how many people it would reach, how many are skipped because they have unsubscribed, and how many because their address is suppressed. A contact in several of the audiences counts once.

The count is taken at the moment of the call. Contacts who join or leave before the send starts change it.

Requires the audiences:read scope.

GET`/broadcasts/analytics`

Broadcast analytics across broadcasts

emails:readReads

The numbers behind the Analytics tab of the Broadcasts page, in one request: how the live broadcasts sent inside a window did, added up and as a series cut to grain, plus one row per broadcast so they can be compared.

A copy counts when it was sent, or written if it has not gone yet, inside the window, and everything that happened to it afterwards counts with it, so an open today of a copy sent last week is in a 30 day window but not in a 1 day one. Test mode broadcasts are left out. totals and series cover the broadcasts in broadcastIds, or every one when it is left out, and broadcasts always lists every broadcast in the window. The series counts each person once, at the first time it happened to them.

A key limited to particular addresses or domains reads only broadcasts sent from an address or domain it holds, and the rest are left out as if they did not exist.

Requires the emails:read scope.

Query parameters

broadcastIdsstring: Comma separated broadcast ids, at most 50, that totals and series add up. Leave it out for every broadcast in the window. A repeated id counts once, and one with no copy in the window adds nothing.
Up to 4000 characters
daysinteger: How far back to look. The window starts at the beginning of its first bucket in the offset you asked for, so the oldest bucket is a whole one, and ends now.
At least 1At most 1095Default30
minutesinteger: The window in minutes, which wins over days when both are sent.
At least 1At most 1576800
grainstring: How wide one bucket is, and the shape of its key: YYYY-MM-DD for a day, YYYY-MM-DDTHH for an hour, YYYY-MM-DDTHH:MM for a minute.
One of"minute""hour""day"Default"day"
offsetMinutesinteger: Minutes east of UTC to cut the buckets in. Pass -new Date().getTimezoneOffset() for the local zone.

GET`/broadcasts/{id}`

Retrieve a broadcast

emails:readReads

One broadcast with counts read live from its copies, which makes this the call to poll while it sends. status settles on sent once every copy handed over has gone out or failed, and on failed or cancelled when it stopped early.

A key limited to particular addresses or domains reads only broadcasts sent from an address or domain it holds. Any other broadcast answers 404 broadcast_not_found, as if it did not exist.

PATCH`/broadcasts/{id}`

Update a draft or a scheduled broadcast

emails:sendaudiences:readChanges data

A partial update: a field left out keeps what it holds, and null clears replyTo, html, text, template or utm. Sending any of html, text or template replaces the body as a whole.

A draft takes every change and stays a draft. A scheduled broadcast takes changes until its sending starts, each checked the way POST /broadcasts checks a new one, and counts.recipients is counted again. scheduledAt moves a scheduled broadcast to another time. Any other broadcast answers 409 broadcast_not_editable.

GET`/broadcasts/{id}/recipients`

List the recipients of a broadcast

emails:readReads

Everybody the broadcast went to, one row per copy, sorted by address: the copy id, its status, when it was sent and delivered, whether it bounced or was reported as spam, how often it was opened and clicked, and whether the person unsubscribed after it went out.

Opens and clicks leave out image proxies and link scanners, and stay 0 when the broadcast was sent with tracking off. Keyset paging: pass nextCursor back as cursor, with the same filter and q.

One of"pending""sent""delivered""opened""not_opened""clicked""bounced""complained""failed""unsubscribed"
qstring: Searches the address and the name, ignoring case.

At least 1At most 200Default50
cursorstring: The previous page's nextCursor, passed back as it came. It is opaque: it holds where the last row sat in this list's order, so a row deleted or edited between pages never breaks the walk, and the next page starts at the first row that sorts after it. A value this list did not hand out is a 400 invalid_cursor.

Returns

200BroadcastRecipientList

A page of recipients, by address.

How the broadcast performed: copies sent, delivered, bounced, reported as spam and failed, and how many people opened, clicked and unsubscribed, as totals and as a series cut to grain. The series counts each person once, at the first time it happened to them, so it adds up to the totals.

Send days or minutes to also read what happened lately: window then counts the copies delivered, bounced, reported, opened, clicked and unsubscribed inside it, and series keeps only its buckets. totals always covers the whole broadcast.

A key limited to particular addresses or domains reads only broadcasts sent from an address or domain it holds. Any other broadcast answers 404 broadcast_not_found, as if it did not exist.

Requires the emails:read scope.

Path parameters

idstringRequired: A brd_ id from POST /broadcasts or GET /broadcasts.

Query parameters

grainstring: Bucket width of the series.
One of"minute""hour""day"Default"hour"
offsetMinutesinteger: Minutes east of UTC to cut the buckets in. Pass -new Date().getTimezoneOffset() for the local zone.
At least -840At most 840Default0
daysinteger: Reads a window too: how far back it reaches. It starts at the beginning of its first grain bucket and ends now. Leave it and minutes out for no window.
At least 1At most 1095
minutesinteger: The window in minutes, which wins over days when both are sent.
At least 1At most 1576800

Returns

200BroadcastStats

Totals, the window and the series.

Errors

404: broadcast_not_found when the id names no broadcast in this workspace.
422: invalid_parameter on days, minutes or offsetMinutes out of range, or on an unknown grain.

POST`/broadcasts/{id}/cancel`

Cancel a broadcast

emails:sendDeletes

Stops a broadcast that is scheduled, queued or sending, including one that has reached everybody while some copies are still waiting to go. Nobody else is added, and every copy still waiting to go is cancelled. A copy already being handed over finishes, and copies that have gone cannot be recalled, so counts.sent keeps them. No body.

Cancelling a cancelled broadcast answers it as it stands, so a retry is safe.

A key limited to particular addresses or domains cancels only broadcasts sent from an address or domain it holds. Any other broadcast answers 404 broadcast_not_found, as if it did not exist.

Requires the emails:send scope.

Path parameters

idstringRequired: A brd_ id from POST /broadcasts or GET /broadcasts.

Returns

200Broadcast

The broadcast, now cancelled.

Errors

404: broadcast_not_found when the id names no broadcast in this workspace.
409: broadcast_not_cancellable: every copy has already gone out, or the broadcast failed.

POST`/broadcasts/drafts`

Save a broadcast draft

emails:sendaudiences:readChanges data

Saves a broadcast with status draft. Nothing is sent, nothing counts against the plan and the audiences may still be empty, so a draft can be written over several sittings. PATCH /broadcasts/{id} changes it, POST /broadcasts/{id}/send sends or schedules it, and GET /broadcasts/{id} returns what it holds in content.

POST`/broadcasts/test`

Send a test of a broadcast

emails:sendSends mail

POST`/broadcasts/{id}/send`

Send a draft

emails:sendaudiences:readSends mail

Turns a draft into a broadcast that goes out: queued straight away, or scheduled with scheduledAt. The draft is checked the way POST /broadcasts checks a new broadcast: it needs an audience, a body, a subject or a template that supplies one, somebody to reach and room in the plan for every copy. A broadcast that is not a draft answers 409 broadcast_not_draft, so a repeated call never sends twice. The body is optional.

Requires the emails:send and audiences:read scopes.

Path parameters

idstringRequired: A brd_ id from POST /broadcasts or GET /broadcasts.

Request body

scheduledAtstring: When to start: an ISO 8601 instant or a duration such as PT2H, in the future and at most 365 days out. Left out, the sending starts straight away.
3 to 64 characters

Returns

202Broadcast

Accepted. The broadcast is queued or scheduled, and nothing has been sent yet.

POST`/broadcasts/{id}/duplicate`

Duplicate a broadcast

emails:sendaudiences:readChanges data

Copies any broadcast into a new draft: the same sender, audiences, left-out audiences, subject, body or template, tracking, tags and campaign tags, without the time it was scheduled for. The original is not changed and nothing is sent. No body.

Requires the emails:send and audiences:read scopes.

Path parameters

idstringRequired: A brd_ id from POST /broadcasts or GET /broadcasts.

Returns

The new draft. The Location header names it.

Errors

POST`/broadcasts/{id}/resend`

Resend to the people who did not open

emails:sendaudiences:readSends mail

Creates a new broadcast with the same content for the people the first one reached and who have not opened it, optionally under a new subject. Somebody who has unsubscribed since, or whose address is now suppressed, is skipped. The new broadcast names the first in content.resendOf and counts against the plan like any send. The first broadcast has to be sent and to have tracked opens, or the call answers 409 resend_unavailable. The body is optional.

Opens are counted from the tracking pixel, so a person whose mail app blocks images can look like they never opened.

Requires the emails:send and audiences:read scopes.

Path parameters

idstringRequired: A brd_ id from POST /broadcasts or GET /broadcasts.

Request body

subjectstring: A new subject for the second try, with merge fields. Left out, the first subject is used.
