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
