Benchmark Email

Benchmark Email is an email marketing platform for small businesses, run by Benchmark Internet Group, with two live REST API generations.

The classic RESTful API v3.0 on clientapi.benchmarkemail.com remains live and documented with 296 operations covering automations, surveys, polls, sub-accounts, galleries and push webhooks. Benchmark publishes an OpenAPI, two llms.txt files, an A2A Agent Card, an Agent Skill and a live documentation MCP endpoint, but ships no maintained SDK, no sandbox, no changelog and no deprecation policy.

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.

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/benchmark-email: open an issue to ask a question, or submit a pull request to add artifacts.
