MailerLite

MailerLite is an email marketing and automation platform used by creators, e-commerce sellers and small businesses to build lists, send campaigns and run behavioural automations. The current REST API at connect.mailerlite.com exposes subscribers, groups, segments, custom fields, campaigns, automations, forms, webhooks, batching, and a full e-commerce surface (shops, products, categories, customers, orders, carts) that drives abandoned-cart and post-purchase automations. Authentication is a bearer API key minted in the dashboard; responses are cursor-paginated and the API version can be pinned with an X-Version date header. Alongside the REST API, MailerLite ships six official SDKs, a first-party Go CLI with an interactive TUI, a published Agent Skill, and a hosted OAuth-protected MCP server at mcp.mailerlite.com exposing roughly 76 tools to AI assistants. A legacy Classic API v2 still serves older accounts.

MailerLite publishes 9 API contracts indexed on the APIs.io network, including Automations API, Campaigns API, Fields API, and 6 more. Tagged areas include Email Marketing, Automation, Newsletters, Subscribers, and Campaigns.

The MailerLite catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

MailerLite’s developer surface includes authentication, developer portal, pricing, CLI, documentation, API reference, getting-started guide, and 46 more developer resources.

Kin Score

Kin Score Kin Score How this is scored →
scored 2026-10-17 · rubric v0.24.0
Regulatory Posture applies to this provider. Its tags matched the Telecommunications regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/mailerlite: open an issue to ask a question, or submit a pull request to add artifacts.
