Tools 67 found in our last check

  • send_email

    Send a transactional email, immediately or scheduled. scheduled_at takes a relative phrase like 'in 3 days' or an ISO timestamp. The From domain must already be verified. Every accepted send answers with the same fields: id, status, thread_id, scheduled_at, skipped, reason and a…

  • list_emails

    List messages newest first with their delivery status, including held, scheduled, skipped and failed ones and the mail campaigns and automations sent. Filter by status, recipient or tag. Paged: at most 100 per call; while has_more is true, next_cursor passed back as cursor with…

  • get_email

    Fetch one message with its full event timeline (send, delivery, bounce, complaint, open, click). The timeline shows why an email didn't arrive.

  • cancel_scheduled_email

    Cancel a scheduled email before it sends. Only works while status is 'scheduled': a message that has already started sending, or is in any other state, answers 409 invalid_state naming its status; a retry answers the same, and get_email shows where it stands. An unknown id answe…

  • update_email_tags

    Add or remove tags on an email already sent, scheduled or held, to refile it for the tag filters of list_emails and list_threads. Removals apply first, then additions, so one call swaps a tag: remove_tags [{name:'recovery_case'}] (no value: every tag with that name) with add_tag…

  • list_sending_domains

    List sending domains with their verification status and the DNS records each one needs. Each record shows what is currently published, so this diagnoses a stuck verification. mail_from says whether SES has adopted the bounce. subdomain as the Return-Path: pending while SES polls…

  • add_sending_domain

    Register a sending domain and get back the DNS records to publish. It takes the domain mail is sent from — mail.<domain> and news.<domain> are provisioned beneath it and the right one is chosen per message, so a marketing complaint spike can never affect password reset delivery.…

  • verify_sending_domain

    Re-check a domain's DNS records now instead of waiting for the background monitor. Also restarts bounce-path (mail_from) verification when SES gave up before the MX record existed.

  • set_utm_tags

    Turn UTM tags on or off for a sending domain, and set what they say. When on, every link in that domain's marketing HTML gets utm_source (default 'newsletter'), utm_medium (default 'email') and utm_campaign (the campaign's name or the automation's slug). A link that already has…

  • list_suppressions

    List addresses we refuse to mail and why (hard_bounce, complaint, unsubscribe, manual, list_hygiene), newest first, each with its scope. When someone reports not receiving email, this shows whether the address is suppressed. email returns one address's suppressions directly; sca…

  • add_suppression

    Stop sending to an address. Scope 'marketing' leaves transactional mail working; the default is 'all'. Reason 'unsubscribe' is a real opt-out: it also cancels the person's queued scheduled sends and ends their automation enrolments, which is what a person who asked to stop expec…

  • remove_suppression

    Remove a suppression so the address can be mailed again. A hard bounce means the address was rejected by the receiving server, and re-sending raises the bounce rate that AWS enforces on. The scope must match the stored one: removed: false means nothing was suppressed in that sco…

  • create_broadcast

    Create a campaign as a draft. Nothing is sent: preview_broadcast reports its reach and send_broadcast sends it. identity_id must be a marketing sending domain (see list_sending_domains; risk_class 'marketing'). topic_key must name an existing topic (list_topics); an unknown one…

  • get_broadcast

    One campaign, with a 'progress' object while it is sending, paused or testing: how many addresses are still pending, sent, failed, or skipped because the person opted out after the campaign started. This is what tells a paused campaign that is still making progress from one that…

  • get_broadcast_metrics

    How a campaign did: sent, delivered, bounced, complained, unique opens and clicks, and open_rate and click_rate over delivered (null until something is delivered). Opens and clicks count only people: a security gateway that followed every link, or a mailbox that loaded every ima…

  • list_broadcasts

    List campaigns, newest first, with their status. Paged: at most 100 per call; while has_more is true, next_cursor passed back as cursor returns the next page. Each row is the campaign object get_broadcast returns, live progress and A/B results included, without its html, which o…

  • preview_broadcast

    How many contacts a campaign would reach, and whether the reputation gate would allow it. It is the only way to see the size of a campaign without starting it. For an A/B test it also reports the sample size and per-variant count against the 100-per-variant floor; a send below t…

  • send_broadcast

    Send a draft or scheduled campaign now, or schedule it with scheduled_at. This mails every contact in the segment and cannot be undone once started; preview_broadcast shows the count beforehand. Marketing mail must carry a postal address: a workspace without one is refused with…

  • pick_broadcast_winner

    Decide an A/B test now instead of waiting for decide_at. 'variant' names the winning key; without it the metric decides on the figures so far. The rest of the audience is then sent to the winner and cannot be redirected. Only a campaign in status 'testing' can be decided; anythi…

  • resume_broadcast

    Continue a paused campaign now. It mails only the addresses still pending — the audience was frozen when the campaign started and everyone already reached is marked — so calling this twice cannot double-send. Only works on a paused campaign; anything else answers 409 invalid_sta…

  • list_threads

    List email conversations. awaiting_reply=true returns only the threads where someone has written in and no answer has been sent, which is what needs a response. A reply held for approval or scheduled does not count as sent: such a thread stays in that list with pending_reply tru…

  • get_thread

    Read a conversation as a chronological transcript of outbound and inbound messages. Inbound `text` already has quoted history and signatures stripped; `raw_text` holds the untrimmed body, for when the stripped version looks wrong. sender_authenticated says whether the sender is…

  • reply_to_message

    Reply to a message, keeping it on the same conversation. Sets the threading headers so the recipient's mail client shows it as part of the existing exchange rather than a new one, which send_email does not do. It is a send, so it answers exactly as send_email does and meets the…

  • mark_thread_handled

    Clear a conversation's awaiting_reply flag without sending anything, for when the last inbound message needs no answer — a "thanks, all sorted" — so it stops appearing in list_threads with awaiting_reply=true. A reply sent only to clear the flag mails a person for bookkeeping; t…

  • list_templates

    List stored email templates and the variables each one needs. Unlike HTML composed at send time, templates carry the workspace's reviewed subject, copy and styling. They do not carry the unsubscribe footer: that is added at send time to marketing mail, whether or not it came fro…

  • render_template

    Render a template with values, without sending, showing how the copy reads before it mails a real person. A missing variable answers 422 missing_variables with the list in `missing`; an unknown slug answers 404. Returns subject, html and text; text is null when the template has…

  • send_template_email

    Send an email built from a stored template. Variable values are HTML-escaped on substitution, so they are safe to fill from user-supplied text. Nothing is sent when a value is missing: 422 missing_variables lists the names in `missing`, and a call with those filled in goes throu…

  • list_media

    The workspace's hosted images, newest first, each with id, filename, content_type, size, width, height and the url to use in an <img src>. Look here before uploading a logo the workspace probably already has. At most 100 per call; while has_more is true, next_cursor passed back…

  • upload_media

    Host an image for use in email HTML: a logo or photo in a template, a campaign or an automation step. Returns a media object whose url goes in an <img src>; it is served from the workspace's own tracking domain (https://link.<sending domain>/media/...), and the url is public to…

  • delete_media

    Delete a hosted image by id (from list_media). Its url stops working within minutes everywhere it is used: in email already delivered, and in any template, campaign or automation step that still references it, where it shows as a broken image. Nothing checks for references, and…

  • list_pending_approvals

    List messages held for human approval, with their full content. A key configured to require approval drafts rather than sends; a person releases it. A send that returned status 'pending_approval' is waiting here, and retrying the send does not release it. Oldest first, each with…

  • decide_approval

    Approve or reject a held message. Approving releases it: it sends now, or at its scheduled_at when the draft was scheduled for later. If every recipient unsubscribed or was suppressed while it waited, nothing is sent and the answer says skipped: true with a reason (both always p…

  • list_automations

    List multi-step email sequences and how many people are currently in each, with the id each one is enrolled by. Newest first, at most 100 per call; while has_more is true, next_cursor passed back as cursor returns the next page. A 'paused' automation holds its people on their cu…

  • get_automation

    Fetch one automation: its status, trigger, steps (each with the id and condition update_automation needs passed back), exit rules and how many people are in each state. The same object list_automations returns, for a caller that already holds the id. People themselves are listed…

  • get_automation_metrics

    How each step of an automation is doing: per current step, its step_id, position, sent, delivered, opened and clicked. Opens and clicks are unique people, counted only after link scanners are ruled out, so they are lower than raw hit counts and reflect readers. Use it to see whe…

  • list_automation_enrollments

    The people in one automation, newest enrolment first: each row has the email, status, current_step, next_due_at and, for a cancelled one, cancel_reason. It answers 'is this person still on the sequence?', 'who is waiting on step 2?' and 'why did this sequence stop for them?', wh…

  • create_automation

    Define a multi-step sequence as a draft; nothing is sent until it is activated, from the dashboard or with set_automation_status. Unlike several separately scheduled emails, it ends on its own when the person unsubscribes, replies, bounces, opts out of its topic, or their tags s…

  • update_automation

    Change a sequence's steps, the rules that take someone out of it (topic_key, exit_tags, required_tags, exit_on_reply), its reply_to, its reenrollment, or its default_variables (replaces the whole set; {} clears it). The trigger is fixed once created. steps replaces every step an…

  • set_automation_status

    Activate, pause or return an automation to draft. A new automation is a draft and sends nothing until it is set to 'active'. Pausing ('paused' or 'draft') holds everyone on their current step: nobody is sent a step and nobody new is enrolled, but nobody's sequence ends, and sett…

  • delete_automation

    Delete an automation for good and cancel every active enrolment in it, so nobody is sent another step. Answers enrollments_canceled. It cannot be undone: to stop it for a while and continue everyone later, use set_automation_status with paused instead. Mail already sent and its…

  • enroll_in_automation

    Put someone into a multi-step sequence. Unlike several separately scheduled emails, the sequence stops on its own if they unsubscribe (from everything or from the automation's topic), reply, hard bounce, gain one of its exit tags, or lose one of its required tags, which would ot…

  • emit_event

    Emit a named event, starting every automation that waits on it — for example 'trial_started' or 'invoice_overdue'. The configured sequences decide what happens, rather than the caller naming an automation. Returns automations_started; 0 means nothing was waiting on that name or…

  • list_conversion_goals

    List conversion goals: the event names counted as a conversion, each with its credit window in days. An emit_event call with one of these names is credited to the last email the person clicked inside that window; any other name is an ordinary event.

  • create_conversion_goal

    Start counting an event as a conversion, such as 'subscription_started' or 'purchase'. Counts only events emitted after this call; it does not go back over earlier ones. Use the exact name the app already passes to emit_event. A name that is already a goal answers 409 conflict,…

  • get_conversion_metrics

    Attributed conversions, converters and revenue per currency. Pass broadcast_id for a campaign, broken down per A/B variant with its sent count and rate, or automation_id for a sequence, broken down per step. The figures are attributed, not causal: each conversion counts for the…

  • list_topics

    List subscription topics — the categories a person can opt out of individually. Marketing mail sent under a topic lets recipients unsubscribe from that kind alone rather than from everything.

  • get_email_preferences

    What one person has chosen to receive. It shows whether someone who isn't getting a particular kind of email opted out of it — an opt-out looks identical to a delivery failure from the outside.

  • set_email_preferences

    Set which topics a person receives, recording what they asked for — silently re-subscribing someone who opted out is what generates spam complaints. Every key must be an existing topic from list_topics: one unknown key refuses the whole call with 422 unknown_topic and nothing is…

  • list_audiences

    List contact lists, newest first, with each one's id and contact_count. Paged: at most 100 per call; while has_more is true, more lists are on later pages, returned when next_cursor is passed back as cursor.

  • add_contact

    Add someone to an audience. A contact exists once per workspace and can be on any number of audiences, so adding an address that already exists joins them to this list rather than creating a second copy. status records that the person opted out elsewhere — it writes the suppress…

  • import_contacts

    Import up to 5,000 contacts into an audience in one call, with names, tags, custom properties and subscription status. This is the migration tool: the previous provider's unsubscribed, bounced and complained lists, imported with the matching status before the first campaign, kee…

  • get_contact

    Fetch one contact by id, with their audience memberships, custom properties and engagement dates.

  • update_contact

    Update a contact. Attributes are merged, so sending one field does not clear the rest. unsubscribed: true is a real opt-out: it suppresses the address for marketing, cancels their pending sends and ends their automation enrolments. unsubscribed: false lifts a marketing unsubscri…

  • list_segments

    List saved audience filters. A campaign created with a segment id, rather than a filter described inline, shares one definition that can be reused and counted.

  • list_tags

    Every tag in use in the workspace, with how many contacts carry each. Tags are free-form, so this is the only way to know what exists before applying one.

  • count_segment

    How many contacts a segment currently matches. A filter that matches nobody shows up here as 0, before any campaign is built around it or sent. Engagement windows and date conditions (e.g. attributes.trial_ends_at within_next_days 3) are measured from the moment of the call, so…

  • get_email_metrics

    Delivery and engagement over a window, for the whole workspace or narrowed to one campaign (broadcast_id) or one tag. Open and click rates are over delivered, not sent — a low open rate with a high bounce rate is a deliverability problem, not an engagement one. Filtered, each da…

  • list_scheduled_emails

    Messages queued to send later but not yet sent, newest first; cancel_scheduled_email cancels one. At most 100 per call; while has_more is true, next_cursor passed back as cursor returns the next page.

  • suppress_many

    Stop sending to many addresses at once — the path for importing another provider's unsubscribe list before a first campaign. Without it, everyone who already opted out there gets mailed again here. The defaults differ from add_suppression: scope 'marketing' and reason 'list_hygi…

  • list_webhooks

    The workspace's webhook endpoints: each with id, url, the events it receives and whether it is enabled. Read-only: endpoints are added and changed in the dashboard, because a tool that could point one at a new URL would let an agent route the workspace's mail events to itself. U…

  • list_webhook_deliveries

    Recent delivery attempts for a webhook endpoint: each with event, status, attempts, last_status_code, last_error and delivered_at (null until it succeeds). This is what tells 'we never sent it' from 'your endpoint returned 500'. Newest first, the most recent `limit` only; not pa…

  • list_broadcast_recipients

    Who a campaign reached and what happened to each message, with the A/B variant when there is one. At most 200 per call; while has_more is true, next_cursor (a message id) passed back as cursor returns the next page.

  • get_usage

    This workspace's plan, what it has sent this billing period, what the period costs so far, and — the fields worth branching on — sending_locked and lock_reason, which name the exact 402 a send would be refused with right now, before a large batch or campaign is tried: on Free a…

  • find_contact

    Find a contact by address across every audience, without knowing which list they are on, or list the workspace's contacts by tag or subscription. email matches exactly, and q matches an address prefix. A person exists once per workspace, so each row is one contact with audience_…

  • remove_from_audience

    Take a contact off one audience. They stay in the workspace and keep every other audience, their suppression and their engagement history. delete_contact removes the person entirely — leaving a list and being forgotten are different things.

  • delete_contact

    Remove a person from the workspace entirely, along with every audience membership. Their suppression and topic preferences are kept on purpose — an opt-out has to outlive the contact record, or the next import silently puts them back on the list. remove_from_audience takes someo…

  • tag_contact

    Add or remove tags on a contact. Tags are flat labels — vip, beta, churned — as opposed to custom properties, which are declared fields with a value. They are lower-cased and spaces become hyphens, so VIP and vip are the same tag. Tagging reaches the person across every audience…
