Emailchaser

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.

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

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.

Retrieves a campaign by ID, including settings, sending schedule, stats and per-status email counts.

Updates campaign properties such as name, emoji, timezone, sending limits and deliverability settings. Only the provided fields are changed.

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

Pauses a running campaign and cancels all currently scheduled emails.

Updates a campaign's sending schedule: timezone, sending days, daily time window and frequency.

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.

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 is allowed and changes future sends only; already-sent emails are untouched.

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

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.
