|---|---|---|---|
filter[status] | string | No | Filter by: active, unsubscribed, unconfirmed, bounced, junk |
limit | integer | No | Subscribers per page (default: 25) |
cursor | string | No | Pagination cursor from previous response meta.cursor |
include | string | No | Set to groups to include group memberships |
Important: Loop with meta.next_cursor until null to build a complete subscriber list.
Retrieve campaigns with optional status/type filters and page-based pagination.
Tool: MAILERLITE_GET_CAMPAIGNS
| Parameter | Type | Required | Description |
|---|---|---|---|
filter[status] | string | No | Filter by: sent, draft, ready |
filter[type] | string | No | Filter by: regular, ab, resend, rss |
limit | integer | No | Items per page (default: 25) |
page | integer | No | Page number (default: 1) |

filter[name] | string | No | Partial name match filter |
limit | integer | No | Max groups to return |
page | integer | No | Page number (starting from 1) |
sort | string | No | Sort by: name, total, open_rate, click_rate, created_at (prefix - for descending) |
Fetch segments and custom field definitions for advanced audience analysis.
Tools: MAILERLITE_GET_SEGMENTS and MAILERLITE_GET_FIELDS

| Parameter | Type | Required | Description |
|---|---|---|---|
limit | integer | No | Max segments to return (max 250) |
page | integer | No | Page number (starting from 1) |
Fields: No parameters required -- returns all custom field definitions.
| Pitfall | Details |
|---|---|
| Subscriber pagination is cursor-based | MAILERLITE_GET_SUBSCRIBERS uses meta.next_cursor -- you must loop until null or counts will be incomplete |
| Campaign pagination is page-based | MAILERLITE_GET_CAMPAIGNS uses page/limit with meta.last_page -- stopping early omits campaigns and distorts trends |
| Sampling bias | Computing engagement metrics from only the first page introduces bias; always aggregate across all pages |
| Nested response shape | MailerLite payloads are nested under results[i].response.data with data and meta subkeys, not a flat data key -- parse accordingly |
| API quotas | Subscriber listing is limited by MailerLite Connect API quotas -- plan batch operations accordingly |
| Tool Slug | Purpose |
|---|---|
MAILERLITE_GET_ACCOUNT_INFO | Verify auth and review account metadata |
MAILERLITE_GET_ACCOUNT_STATS | Get aggregate performance metrics |
MAILERLITE_GET_SUBSCRIBERS | List subscribers with filtering and pagination |
MAILERLITE_GET_CAMPAIGNS | List campaigns with status/type filters |
MAILERLITE_GET_GROUPS | List and sort subscriber groups |
MAILERLITE_GET_SEGMENTS | List audience segments |
MAILERLITE_GET_FIELDS | Retrieve custom field definitions |
