Core Workflows

1. List and Discover Campaigns

Use LEMLIST_GET_LIST_CAMPAIGNS to enumerate all campaigns by status, with pagination support.

Tool: LEMLIST_GET_LIST_CAMPAIGNS Inputs:

• status: "running" | "draft" | "archived" | "ended" | "paused" | "errors" (optional)
• limit: integer (max 100, default 100)
• offset: integer (pagination offset)
• sortBy: "createdAt"
• sortOrder: "asc" | "desc"

Important: The response may be wrapped as {campaigns: [...], pagination: {...}} instead of a flat list. Always extract from the campaigns key.

2. Get Campaign Details

Use LEMLIST_GET_CAMPAIGN_BY_ID to validate campaign configuration before writes.

Tool: LEMLIST_GET_CAMPAIGN_BY_ID Inputs:

• campaignId: string (required) -- e.g., "cam_A1B2C3D4E5F6G7H8I9"

3. Enroll Leads into a Campaign

Use LEMLIST_POST_CREATE_LEAD_IN_CAMPAIGN to add leads with optional email finding, phone lookup, and LinkedIn enrichment.

Tool: LEMLIST_POST_CREATE_LEAD_IN_CAMPAIGN Inputs:

• campaignId: string (required)
• email: string (required)
• firstName, lastName, companyName, companyDomain: string (optional)
• jobTitle, phone, linkedinUrl, icebreaker: string (optional)
• deduplicate: boolean (prevents cross-campaign duplicates)
• findEmail, findPhone, verifyEmail, linkedinEnrichment: boolean (optional)
• timezone: string (IANA format, e.g., "America/New_York")

Bulk pattern: Chunk leads into batches of ~50 and checkpoint progress between batches.

4. Add Custom Variables to a Lead

Use LEMLIST_POST_ADD_VARIABLES_TO_LEAD to enrich leads with personalization fields after enrollment.

Tool: LEMLIST_POST_ADD_VARIABLES_TO_LEAD Inputs:

• leadId: string (required) -- internal Lemlist lead ID (NOT email)
• company: string (required) -- must match your company name in Lemlist
• variables: object (required) -- key-value pairs, e.g., {"score": "42", "color": "yellow"}

Important: This is NOT an upsert -- attempting to add variables that already exist will fail. Resolve the internal leadId via LEMLIST_GET_RETRIEVE_LEAD_BY_EMAIL if you only have the email address.

5. Export Campaign Leads

Use LEMLIST_GET_EXPORT_CAMPAIGN_LEADS to download leads with state filtering for reporting or QA.

Tool: LEMLIST_GET_EXPORT_CAMPAIGN_LEADS Inputs:

• campaignId: string (required)
• (supports state filtering and JSON/CSV output)

6. Unsubscribe Lead from Campaign

Use LEMLIST_DELETE_UNSUBSCRIBE_LEAD_FROM_CAMPAIGN to stop outreach by removing a lead from a campaign.

Tool: LEMLIST_DELETE_UNSUBSCRIBE_LEAD_FROM_CAMPAIGN Inputs:

• campaignId: string (required)
• leadId or email: string (required)
