Postmark MCP
activecampaign · MCP server
Postmark MCP connects your AI assistant to a Postmark account. Its 24 tools send single and batch email, including from templates, create and edit templates with validation, search messages, diagnose delivery, handle bounces and suppressions, read stats and manage webhooks. It needs a Postmark server API token, a verified default sender and a message stream, and every send has open and click tracking. It suits people who already send email through Postmark.

Why it's useful
Your agent can send and troubleshoot email in Postmark directly, with tool markings that let your client ask before it sends or deletes anything.
What you could do with it
- Ask your agent to send an email, or a batch, from a template stored in your Postmark account.
- Search sent messages and have your agent diagnose a delivery problem or a bounce.
- Register a webhook for your account, limiting it to an allowlist of HTTPS addresses.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 2.1.1, the file with digest sha512-ygQM80bgMY7z3nKrpVQMw2Y6/EoUH12OCoNIaWdQw+rZdDsAJysyi5F8oKTTS+Ks8OOoVtRhiJakrIzBd3RC5Q==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.
The badge, if this is your listing
It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
