Tools 80 found in our last check

• confirm_connection

  Confirms the API key works and tells Emailchaser which AI assistant connected. Use it when the user connects Emailchaser or asks 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…

• list_campaigns

  Lists cold email campaigns in the workspace with their status and stats (sent, replies, bounces). Supports pagination and filtering by status or folder.

• create_campaign

  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 it has a sequence and a sender email attached. Sending limits and deliverability settings can be set here or changed later.

• get_campaign

  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,…

• update_campaign

  Updates campaign properties such as name, emoji, timezone, sending limits, the minimum email account health score and deliverability settings. Only the provided fields are changed. A new minimum health score re-plans a running campaign at once.

• launch_campaign

  Launches a new campaign or resumes a paused one. The campaign configuration is validated before launching; emails start sending per the campaign schedule.

• pause_campaign

  Pauses a running campaign and cancels all currently scheduled emails.

• update_campaign_schedule

  Updates a campaign's sending schedule: timezone, sending days, daily time window and frequency. everySchedule can be left out: the campaign keeps its current frequency, or 5 minutes (the app's default) if it has none.

• get_campaign_sequence

  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.

• replace_campaign_sequence

  Replaces a campaign's WHOLE sequence with the steps provided. This is not a partial edit: steps you leave out are removed, so send the full sequence every time. Sending the same payload twice leaves the same result, so a retry cannot duplicate steps. Editing a running campaign i…

• delete_campaign

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

• get_campaign_stats

  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 anyw…

• attach_campaign_sender_emails

  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…

• detach_campaign_sender_email

  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…

• move_lead_to_campaign

  Moves a lead from one campaign to another: the lead's unsent emails in the source campaign are deleted, and if the target campaign is running, emails for the lead are enqueued there. Use it to re-route a lead into a better-fitting campaign.

• list_leads

  Lists the leads in the workspace, newest first, 20 per page. Filter by exact email to look up a single lead, or by campaign to list only that campaign's leads. This is how you find the ID of a lead you added earlier.

• add_leads

  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 t…

• get_lead

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

• update_lead

  Updates a lead's contact details. Only the provided fields are changed.

• delete_lead

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

• get_lead_conversation

  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. Every inbound reply in the thread, with or without an AI draft…

• mark_lead_meeting

  Records that a meeting was actually booked with this lead: sets meetingBookedAt to now, sets the lead's category to meeting_booked and fires the LeadCategoryUpdate webhook. Emailchaser never infers meetings from reply text or calendars, so this explicit mark is the only way a me…

• unmark_lead_meeting

  Removes the booked-meeting mark from a lead, e.g. when it was recorded by mistake or the meeting was canceled: clears meetingBookedAt and, when the category is still meeting_booked, reverts it to interested. The original booked time is lost. Idempotent: unmarking a lead with no…

• update_lead_category

  Sets or corrects a lead's category (tag), typically to fix an AI misclassification of a reply. Setting meeting_booked behaves exactly like marking a meeting as booked. Changing the category away from meeting_booked does NOT clear the booked-meeting mark: that mark is removed onl…

• list_replies

  Lists inbound emails (replies received from prospects) in the workspace, newest first, 20 per page. Filter by AI response category, campaign, lead or a time floor. responseCategory is null while AI categorization is still pending. This tool only lists. Any reply can be answered…

• list_reply_drafts

  Lists AI-suggested reply drafts awaiting review, newest first, 20 per page. Each draft answers the inbound reply referenced by inReplyToEmailId. Nothing here has been sent: a draft stays a draft until it is sent. A draft's subject and body can be edited before it goes out.

• update_reply_draft

  Edits the subject and/or body of an AI reply draft before it goes out. Provide at least one field; provided fields must be non-empty. This never changes the draft's status or sends anything: the draft stays a draft until it is sent. Emails that are not AI reply drafts (sent or s…

• send_reply_draft

  Sends an AI reply draft to the prospect through the conversation's sender mailbox; it is scheduled for delivery right away and cannot be recalled. The draft's CURRENT subject and body are what goes out, so check its wording before sending: an edit has to be made before it is sen…

• send_reply

  Answers an inbound reply with your own message, in the same email thread and from the mailbox the conversation runs through (in a conversation the prospect started, your mailbox they wrote to). It works for every inbound reply, including the ones Emailchaser writes no AI draft f…

• list_sender_emails

  Lists the sending email accounts in the workspace, 20 per page, with their connection status, daily limits and health score. Filter to one campaign's senders, to connected or disconnected mailboxes only, or to one workspace on the account. healthScore is the account's health sco…

• get_sender_email

  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 email…

• connect_sender_email

  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 busin…

• update_sender_email

  Updates a connected sending email account's display name, signature or daily sending limits. Only the provided fields are changed. Warm-up settings are separate and are not changed here. The returned account includes its healthScore (0-100, higher is better; null while warm-up i…

• get_sender_email_dns

  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 c…

• get_sender_email_warmup

  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…

• update_sender_email_warmup

  Switches warm-up on or off and changes the warm-up ramp for up to 100 mailboxes in one call, applying the same settings to each. Only the settings provided change. Warm-up sends startLimit emails on the first day and adds increaseBy each sending day until it reaches capLimit a d…

• list_inbox_placement_tests

  Lists every inbox placement test defined in the workspace, newest first. A test is the definition: the email content, which mailboxes send it and, for a recurring test, how often it runs. Each execution of a test is a run. Inbox placement is a paid add-on: a workspace without it…

• list_inbox_placement_runs

  Lists inbox placement runs, newest first, optionally only those of one test. Each run counts how many probe emails landed in the inbox, in spam, in a Gmail category tab (promotions) or nowhere (missing, which usually means a silent block). Counters are only final once status is…

• get_inbox_placement_run

  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'…

• list_inbox_placement_run_results

  Returns one row per probe email of a run: which of your mailboxes sent it, which seed mailbox received it, where it landed and how many seconds it took to arrive. deliverySeconds is worth watching on its own: greylisting and throttling show up there before they show up in a plac…

• get_inbox_placement_stats_by_date

  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.

• get_sender_reputation

  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…

• get_deliverability_insights

  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 measur…

• list_webhooks

  Lists the webhook endpoints registered for the workspace, with their event type and status.

• create_webhook

  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). API reference: https://www.emailchaser.com/docs/api-reference/webhooks

• update_webhook

  Updates a registered webhook's name, URL, event type or enabled state. Only the provided fields are changed. Disabling a webhook stops deliveries without deleting it. API reference: https://www.emailchaser.com/docs/api-reference/webhooks

• delete_webhook

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

• list_blocklist_entries

  Returns the suppression entries (blocked domains and email addresses) that apply to this workspace, newest first. Blocked entries are never emailed by any campaign. By default that spans both lists: this workspace's own entries and the account-wide ones inherited from the main w…

• add_blocklist_entries

  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…

• remove_blocklist_entries

  Unblocks up to 1,000 domains or email addresses in one call, so campaigns can email them again. Pass values (domains or addresses, matched case-insensitively) and/or ids (blocklist entry IDs); a value that is not blocked is counted as skipped rather than failing the call. Scope…

• get_blocklist_entry

  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".

• update_blocklist_entry

  Changes one suppression entry's blocked value, its scope, or both; provide at least one. A value containing @ is stored as an email address, otherwise as a domain, so an entry can be converted between the two. Moving an entry to or from the account-wide list ("global") requires…

• remove_blocklist_entry

  Removes one suppression entry by ID, so campaigns can email that domain or address again. This cannot be undone: the entry and the record of when it was added are gone. A sub-workspace key cannot remove an account-wide entry it merely inherits. It removes one entry per call.

• import_instantly

  Imports your Instantly.ai campaigns and leads into Emailchaser using your Instantly API key. Imported campaigns are created as DRAFTS — nothing sends until you review and launch them. Runs in the background and returns a job id.

• list_instantly_accounts

  Fetches the sending accounts of an Instantly.ai workspace using your Instantly API key, together with a pre-filled CSV for Emailchaser's bulk IMAP/SMTP connection flow. A read-only preview before an import: nothing is written to the workspace. Mailbox passwords cannot be exporte…

• copilot_plan

  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.

• copilot_launch

  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…

• create_icp

  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. The profile is stored as given: it i…

• list_icps

  Lists the workspace's stored Ideal Customer Profiles (ICPs), newest first, with their targeting criteria, whether each is AI-generated or human-edited, and the estimated audience size.

• get_primary_icp

  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.

• get_icp

  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.

• update_icp

  Applies a partial edit to an Ideal Customer Profile: omitted fields are left unchanged, and sending an empty list clears that list. Any edit marks the profile as human-authored.

• delete_icp

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

• set_primary_icp

  Promotes an Ideal Customer Profile to the workspace's active one, demoting any existing primary. At most one profile is primary per workspace.

• refresh_icp_audience_size

  Re-counts how many prospects match an ICP's targeting criteria against the live data provider and caches the result on the profile. Sizing is free — it never spends credits; only revealing contact details is metered.

• get_audience_size

  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 size an audience and validate targ…

• source_prospects

  SPENDS CREDITS. Queues a background job that searches Emailchaser's contact database with an Ideal Customer Profile's targeting criteria, reveals the matching people and adds them to the campaign as leads. Uses the workspace's primary ICP when icpId is omitted, and adds 50 prosp…

• get_lead_finder_filters

  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 r…

• search_lead_finder

  Searches Emailchaser's B2B contact database (Lead Finder) with explicit filters and returns one page of matching people, masked: first name, last initial, title, seniority, job function, company name, industry, size and revenue band, and location. Email addresses, domains, Linke…

• get_lead_finder_search

  Reads a Lead Finder search again by its searchId, the id returned when the search was run. 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. The exact…

• add_lead_finder_prospects

  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 Lead Finder search results; up to 1,000 different people by default) to add ex…

• list_lead_finder_imports

  Lists the workspace's Lead Finder adds (people added to campaigns from the contact database), newest first, each with its progress: requested, added, skipped and why, what email verification said, and credits spent.

• get_lead_finder_import

  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 pol…

• cancel_lead_finder_import

  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 fi…

• plan_autopilot

  Turns a monthly budget in dollars into a concrete outbound setup: how many domains and mailboxes it buys, monthly sending volume, prospects per month, and costs (one-off setup, recurring, first month). creditsUsd, recurringUsd and firstMonthUsd value prospect credits at the list…

• start_autopilot_run

  Starts an autopilot run for a company website: the AI builds an ICP, writes a sequence and checks that prospects match, then STOPS at an approval gate. Nothing is revealed, charged or sent and no sending accounts are bought until the run is approved; approval then reveals the fi…

• list_autopilot_runs

  Lists the workspace's autopilot runs, newest first, with status (pending, building_icp, writing_sequence, sourcing_prospects, awaiting_approval, running, paused, completed, failed) and linked ICP/campaign IDs.

• get_autopilot_run

  Returns one autopilot run including its full audit trail. It does not return the budget plan: that is returned only in the response that started the run, when budgetUsd was given. Use it to check progress.

• approve_autopilot_run

  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…

• pause_autopilot_run

  Suspends an autopilot run that is still in flight; a paused run can be resumed later. Pausing never skips the approval gate. A completed or failed run cannot be paused.
