Known Pitfalls
| 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 |

FAQ
How do I connect my MailerLite account?
You need to connect your MailerLite account through the Composio MCP server at the link provided in the documentation. The agent can guide you with an authentication link.
What are 'groups' and 'segments'?
Groups are lists of contacts you can create (e.g., 'VIP Customers'). Segments are subsets of contacts based on specific rules (e.g., 'contacts who opened the last email').
Why might the contact list be incomplete?
The tool that lists contacts has a limit per request and uses a 'cursor' system to fetch more. You need to ask it to fetch all pages to get the complete list.
