Emailchaser

Adds up to 1,000 suppression entries in one call so no campaign ever emails them. Each value is either a full email address (contains @) or a bare domain; the type is inferred per value. Existing entries and invalid values are skipped, so the call is safe to retry and suited to carrying over a suppression list from another sending platform. Scope defaults to "workspace"; "global" blocks across every workspace on the account and only works from the main workspace.

SPENDS CREDITS, AND BY DEFAULT METERED EMAIL VERIFICATION. Adds people from the Lead Finder contact database to a campaign as leads, revealing their contact details, in the background. Pass refs (from search_lead_finder results; up to 1,000 different people by default) to add exactly those people, or pass filters and count (1 to 5,000 by default) to add count people matching the filters who are not in the workspace yet. A filters add always walks the matches from the top and skips anyone already a lead, free and not counted, so repeating the same add adds the NEXT count people and charges again. Never repeat an add to retry: after an error or a timeout, call list_lead_finder_imports to see whether it started. A filters add stops early when the audience runs out or once it has looked at five people for every one requested (at least 1,000). People already added count toward that limit even though skipping them is free, so after an add of more than about 1,000 people a small follow-up can stop with nobody added. Every person a filters add looks at, added or skipped, also uses the account's daily allowance for filters adds (25,000 people by default). Each person added costs 1 credit ($0.033 at list), reported as creditsPerProspect; the response reports estimatedCredits, the most the add can cost in credits, and the wallet must hold that much for it to start. People already in the workspace, blocklisted, without a usable address, on a personal mailbox when the campaign only takes business addresses, or marked invalid by verification are skipped and cost no credits. verifyEmails (on by default) checks every screened address with the paid email verification waterfall, including the ones it marks invalid: one or two checks per address, billed as metered usage on the next invoice (price per check: GET /email-verification/rates in the REST API), within the account's monthly verification spend limit. Catch-all and unconfirmed addresses are added and charged, and so is every address once that limit is reached; verification.limitReached and verification.unknown on get_lead_finder_import count them. Leads added to a running or paused campaign get their emails at once (a paused campaign sends them when resumed); adding to a completed campaign resumes it, so it starts sending again; in a draft campaign the emails are created at launch. At most 3 adds run at once in a workspace. A refusal names its reason, and a 429 also says when to retry (reason running_imports, daily_import_limit, daily_budget, monthly_budget or fair_use_floor). Poll get_lead_finder_import with the importId until finishedAt is set. Check get_credit_balance first; buy credits with purchase_credits.

Creates or updates up to 1,000 leads in one request, optionally adding them to a campaign via campaignId. Existing leads (matched by email) are updated instead of duplicated. Returns the id of every lead written, so they can be fetched or updated afterwards. Attributes outside the named fields can be passed in customVariables and become merge tags in email copy.

Approves an autopilot run that is awaiting approval — the one human gate in the flow. CAN SPEND REAL MONEY: approval first reveals the run's prospects at 1 credit ($0.033 at list) each, then, if the workspace has no connected sending account, places one done-for-you order sized from the plan snapshotted at start, at most 10 .com domains and at most six mailboxes per domain, never more mailboxes than the plan, charged at the prices in effect when the order is placed. So the plan's mailbox and domain counts are a ceiling and its dollar figures an estimate, not an exact quote. No credits are bought, but the reveal and later top-ups spend the wallet's credits. If a sending account is already connected, no infrastructure is bought; a run started without budgetUsd and with no connected account fails. Show the user the plan from the start_autopilot_run response before calling this. Nothing is revealed, bought or sent before this call; after it, sending starts without further confirmation.

Attaches connected sender email accounts to a campaign. A campaign only sends through the senders attached to it, so this call decides which mailboxes it uses. Idempotent: already-attached senders are left untouched and only missing ones are added. The call is refused whole when any requested sender is not a connected sender email in the workspace. Attaching to a running campaign reschedules it so the new senders are picked up.

Stops a running verification job. Addresses already verified stay in the results and stay billed; addresses that never ran are never charged, so cancelling costs nothing further.

Stops a running Lead Finder add. It reads canceled at once. A batch the worker is already writing is still added and charged; a batch still being screened or verified is dropped, though verification checks already made are billed. Credits held for the rest are released. Until finishedAt is set, added, creditsSpent and even status can still change: if that batch was the add's last, it ends completed or failed instead. People already added stay in the campaign. A stopped add cannot be resumed: start a new add_lead_finder_prospects instead. Stopping one that already finished changes nothing.

Confirms the API key works and tells Emailchaser which AI assistant connected. Call it as your first action after connecting, and whenever the user asks you to confirm or check the Emailchaser connection: it records the assistant and time on the key, which the app's API & MCP page watches to show the user you are in, and completes the 'Connect your AI' onboarding step. Idempotent: repeat calls simply refresh the record. Works with read-only keys as well as read & write keys.

Connects an SMTP/IMAP mailbox to the workspace using an app password, with no browser step. Google and Microsoft mailboxes are NOT supported here because both require an interactive consent screen that cannot be automated; connect those in the app. The address must be on a business domain, so gmail.com and similar are rejected. The returned account's healthScore is null until warm-up has checked 20 of its emails (see get_sender_email).

Creates a DRAFT campaign from a sequence. With a LinkedIn Sales Navigator search it also starts finding + verifying leads for it; without one the draft holds the emails and leads can be added from Lead Finder or a CSV upload. Nothing sends — the campaign stays a draft until you review and launch it. Returns the new campaign id, plus a lead-finding job id when lead finding started.

Given a company website, the honest AI SDR builds an ideal-customer-profile (ICP) and a suggested cold-email sequence. Read-only — creates nothing. Returns the ICP (personas, titles, industries, suggested Sales Navigator keywords) and a draft sequence you can review or pass to copilot_launch.

Creates a campaign in the workspace. The campaign starts as a DRAFT and sends nothing. A new campaign has no emails in it, so it cannot be launched until a sequence is written with replace_campaign_sequence and a sender email is attached. Sending limits and deliverability settings can be set here or changed later with update_campaign.

SPENDS REAL MONEY. Places a real order for sending domains and pre-warmed mailboxes: domains are registered at their listed price (about $13.99/year for a .com — search_dfy_domains shows the exact price per domain) and each mailbox costs about $3 setup plus $6/month. The order is accepted immediately and provisioned in the background; poll get_dfy_order for progress. Purchased domains redirect visitors to forwardingDomain. Use search_dfy_domains first to confirm availability and price. Every domain in domains needs at least one mailbox in mailboxes whose domainName is that domain, or the order is refused before anything is bought; mailboxes can also go on a domain from an earlier order.

SPENDS MONEY: every address checked adds metered usage to the workspace's next invoice. This does NOT use prospect credits and it does NOT create or send a campaign — it verifies a list on its own and gives back a per-address verdict you can download as CSV. Call get_email_verification_rates first for the current price: an address costs one verification credit when the first provider rejects it outright and two when both providers answer, so multiply your list size by perAddressCeilingUsd to budget. An address that gets no verdict is NOT billed and comes back with result unknown. Duplicates are removed and unparseable entries are returned in invalid_emails before anything is charged, so the total in the response is what will be billed against, not what you submitted. Needs an active or trialing subscription: a past_due workspace is refused with subscription_not_active, and a trialing workspace may submit up to 100 addresses in total across all its jobs, after which it is refused with trial_allowance_exceeded (the message says how many are left). If the workspace's monthly verification allowance runs out mid-job the job does not fail — the remaining addresses come back unknown, marked, still in the download, and unbilled. Poll get_email_verification_job until state is done, then read the results with list_email_verification_results.

Stores a manually-authored Ideal Customer Profile (ICP): who the workspace sells to, as targeting criteria (titles, seniorities, industries, company sizes, locations, keywords). Set makePrimary to promote it to the workspace's active profile. Use copilot_plan instead when you want the AI to build the ICP from a website.

Registers a webhook endpoint that receives a POST request whenever the selected event happens (email sent, reply received, bounce, lead created, lead category updated, or campaign status changed).

Creates a sub-workspace under the account's main workspace (for example one per client, for an agency) and by default mints a read & write API key bound to it. The key's fullKey is returned exactly ONCE and cannot be retrieved again, so hand it to the user straight away; it never outlives the calling key. Must be called with the main workspace's key: sub-workspace keys are refused. Workspaces are a Professional-plan feature.

Mints a new API key bound to a workspace the calling key already owns: its own workspace, or one of its sub-workspaces when called with the main workspace's key. This is how a workspace whose key was lost gets a new one without a UI step. fullKey is returned exactly ONCE and cannot be retrieved again, so hand it to the user straight away. The new key authorizes the named workspace only and never outlives the calling key. Keys can be revoked in the app under API & MCP.

Permanently deletes a campaign and all associated data, including its emails, sequences and scheduled tasks. This cannot be undone.

Deletes an Ideal Customer Profile. Deleting the primary leaves the workspace without an active profile. This cannot be undone.

Permanently deletes a lead by ID. This cannot be undone.

Deletes a registered webhook endpoint by ID so it stops receiving events.

Detaches a sender email from a campaign so the campaign stops sending through that mailbox. Unsent follow-ups to emails this sender already sent are canceled and do not come back on re-attach; a running campaign is rescheduled onto its remaining senders; already-sent emails are untouched. Idempotent: detaching a sender that is not attached is a no-op.

Counts how many prospects match ad-hoc targeting criteria (titles, seniorities, industries, company sizes, locations, keywords) without saving anything. Free — searching never spends credits; only revealing contact details is metered. Use it to validate targeting before creating an ICP or sourcing leads. A read-only key may call it: a read-only key can use the read (list and get) tools plus confirm_connection, get_audience_size and search_lead_finder.

Returns one autopilot run including its full audit trail. It does not return the budget plan: that comes back only from start_autopilot_run (when budgetUsd was given) and from plan_autopilot. Use it to check progress.

Returns the registrant and postal contact details held for the workspace: what is filed with the registrar when a done-for-you order buys a domain, and the postal address a CAN-SPAM footer must carry. Errors with 404 until set_billing_profile has been called.

Returns one suppression entry by ID: the blocked domain or email address, when it was added and which list it belongs to. Entries inherited from the account-wide list are visible from a sub-workspace too and report scope "global".

Retrieves a campaign by ID, including settings, sending schedule, stats and per-status email counts. minimumHealth lists each connected email account on the campaign with its healthScore and whether the campaign's minimum health score (settings.minimumHealthScore) holds it back, with the reason; when every account is held back, allHeldBack is true and message says the campaign is sending nothing.

Returns the ordered emails that make up a campaign's sequence, including any A/B variants. delayDays on each step is counted from the previous step, and the first step is always 0.

Returns a campaign's performance in one call: totals (sent, replied, positive, bounced, meetings), per-A/B-variant results, per-sequence-step results and a daily time series (UTC days). Use it to judge how a campaign is doing or to compare variants. There is no opens metric anywhere in the response: Emailchaser does not track opens, so its absence is deliberate, not an omission.

Returns the workspace's credit wallet: available, reserved, lifetime granted and used, and the monthly grant. Credits pay for prospect reveals and AI work (list price $0.033 each). A new workspace sees zeros, not an error. unlimited is true when Emailchaser has made this workspace's credits free: every credit action then goes through without using available and is never refused for lack of credits, so there is no need to check the balance or buy credits.

What is wrong with deliverability across the workspace right now, worst first, each with the action that fixes it. Combines the inbox placement measured over the window with the latest health check of every connected mailbox: authentication records, blacklist listings and measured placement per mailbox. The best first call when asked 'why are we landing in spam'.

Returns one done-for-you order: status (created, pending_approval, processing, completed, failed, partially_completed, canceled), cost breakdown and any failure reason. Poll it to track provisioning after create_dfy_order.

Returns one verification job: its state, per-verdict counts and what it has billed. Poll until state is done. An errorCode of monthly_limit_reached means the allowance ran out and the remaining addresses came back unknown rather than missing — they are still in the results, marked, and were not billed.

Returns what one email verification costs right now, read from the billing plan the meter actually charges against. Call this before create_email_verification_job rather than assuming a price. Every check runs a waterfall of up to two providers and each one that returns a verdict is one billable verification credit, so an address costs ONE credit when the first provider rejects it outright and TWO when both answer. Budget against perAddressCeilingUsd, which is the common case, not perAddressFloorUsd.

Retrieves one Ideal Customer Profile by ID, including its targeting criteria, whether it is AI-generated or human-edited, primary status and estimated audience size.

Returns one inbox placement run with its complete report: the headline inbox / spam / promotions / missing split, the breakdown per mailbox provider and per sending mailbox, and the content spam rules the copy triggered. 'Promotions' rolls up every Gmail category tab. 'Missing' means the probe was never found in any folder, which usually indicates a silent block: a worse problem than spam, with a different fix. spamScore is in tenths of a point (47 means 4.7) and -1 means not scored.

Rolls completed inbox placement runs up by UTC calendar day over a window, for a trend. Defaults to the last 30 days. Days on which nothing ran are ABSENT from the series rather than zero: never report a missing day as 0% placement, it means nobody ran a test that day.

Retrieves a lead by ID, including contact details and company information.

Returns a lead's full email thread in chronological order: outbound emails (sent, scheduled and unsent drafts) plus inbound replies, each with direction and status. AI reply drafts awaiting review are marked isDraft; edit one with update_reply_draft and send it with send_reply_draft (or a human sends it from the app). To write your own answer to any inbound reply in the thread, use send_reply with that reply's id. Use it to read the back-and-forth with one lead before deciding what to do next.

Returns the values Lead Finder's list filters accept (seniorities, jobFunctions, companySizes, revenue, industries, countries, headquartersCountries, regions, continents), the limits that apply to this workspace (page sizes, deepest page, people per add, first-N count, imports running at once, and the daily browsing allowance with what is left today), and creditsPerProspect, what adding one person to a campaign costs. Free, and makes no call to the data provider. Call it before search_lead_finder so filter values match exactly.

Returns one Lead Finder add's progress: status (running, completed, failed or canceled), how many people were added and skipped and why (skipReasons), what email verification said, and credits spent. added, creditsSpent and status can still change until finishedAt is set, so poll it after add_lead_finder_prospects until it is. A completed add's endReason is all_selected, requested_reached, audience_exhausted or fetch_limit, and a canceled one's is canceled. A failed add can still have added and charged people (see added and creditsSpent); lastError says why it stopped: insufficient_credits, contact_cap_reached, results_expired, budget_exhausted, provider_blocked, invalid_filters, campaign_not_found or internal. A new filters add to finish a partial one starts from the top again and counts the people already added toward its fetch limit (five people per one requested, at least 1,000), so after a large add, pick the missing people by ref from search_lead_finder results instead.

Reads a search started with search_lead_finder, by its searchId. While it is still running, or while its exact total is still being counted (totalStatus pending), the call waits up to about six seconds, so calling again straight away is fine. A finished page can be re-read for 10 minutes after it was fetched (less if it came from cache), and re-reading it in that window keeps its refs valid for another 60 minutes. After that the call answers status failed with error expired, though refs already shown stay usable until 60 minutes after they were last shown; running search_lead_finder again shows them afresh and uses browsing rows. After 15 minutes the search is not found.

Puts money against results for a time window: credit spend (grouped by reason, valued at the $0.033 list price) plus done-for-you order costs on one side, and sent emails, replies, positive replies and booked meetings on the other, with cost per reply, per positive reply and per meeting. Subscription fees are NOT included. campaignId narrows the outcome side only — spend stays workspace-level — so per-campaign cost figures are partial attribution, not a true campaign cost. Use it to answer 'what did we spend and what did we get'.

Returns the workspace's active (primary) Ideal Customer Profile — the profile the workspace currently targets; at most one is primary. Errors with 404 when none is set.

Retrieves a connected sending email account by ID, including its health score. healthScore is the account's health score: 0-100, higher is better, the share of its warm-up emails over the last 7 full days that landed in the inbox rather than spam. It moves daily as warm-up emails land in the inbox (up) or in spam (down), and is null while warm-up is off or before 20 warm-up emails were checked.

Checks the sender domain's SPF, DKIM, DMARC and MX records and reports each as OK, WARNING, MISSING or ERROR with human-readable issues (the same checks behind the app's DNS vitals view), plus the mailbox's warm-up status: whether it is enrolled, today's ramp target, the daily cap and its healthScore (0-100, higher is better, the share of its warm-up emails over the last 7 full days that landed in the inbox rather than spam). Use it to diagnose deliverability. DNS lookups run live at request time, so the call can take a few seconds but never returns stale records.

Reads a mailbox's warm-up settings: whether warm-up is on, the ramp (startLimit warm-up emails on the first day, increaseBy more each sending day, up to capLimit a day), weekdays-only, timezone, today's ramp target (currentPerDay) and the account's healthScore (0-100, higher is better, the share of its warm-up emails over the last 7 full days that landed in the inbox rather than spam; null while warm-up is off or before 20 were checked). Warm-up volume is separate from the campaign sending limits changed with update_sender_email. When configured is false the mailbox has never warmed, and the values shown are the defaults that switching warm-up on would use.

Returns the latest health check for every connected mailbox: SPF, DKIM, DMARC and MX status (OK, WARNING, MISSING or ERROR), blacklist listings with their delisting links, measured inbox placement over recent runs and a combined 0-100 health score. blacklistsChecked is reported next to blacklistsListed so the count is never read as a total. A placementScore or healthScore of -1 means not measured, not zero.

Returns the workspace behind the API key: campaign counts broken down by status and the list of members. Useful as a first call to confirm which workspace a key belongs to.
