How do I connect NoClick to Mailgun?

The Mailgun node authenticates with your Mailgun API key. Add the key once as a credential in NoClick and every operation runs against your account, from listing domains to adding mailing list members. Point the node at the domain you send from so events and lists resolve correctly.

Can a workflow react to email events like opens, clicks, or bounces?

Yes. The node includes triggers for accepted, delivered, opened, and clicked events, plus hard bounce and inbound email, so a workflow starts the moment Mailgun records the event. From there you can update lists, log engagement, or clean bad addresses automatically.

Can it manage mailing lists and members?

Yes. You can create a mailing list, add a single member, bulk add many at once, list current members, and delete members that are no longer valid. That covers building a list from a form or an import and keeping it clean over time.

Can NoClick handle inbound email with Mailgun?

Yes. Create a route to catch inbound mail, then use the inbound email trigger together with Get Stored Message to pull the full message into the workflow. That lets you parse, classify, or route incoming email through later nodes.

Can it manage templates and sending domains?

Yes. The node creates domains, fetches domain details, and lists all domains, and it can create templates, add new template versions, and read existing templates. You can automate onboarding a new sending domain or updating a template across your account without touching the dashboard.

How does Codex get access to my apps?

You connect an integration to the agent's tools handle and select which operations to expose. Codex then calls those operations as tools, authenticated with the credentials you connect in NoClick.

Is this the same Codex CLI?

Yes. NoClick runs the Codex harness for you and adds your connected apps as tools. You do not have to install or manage anything locally.

Can I trigger a Codex agent automatically?

Yes. Because it runs hosted, you can start it from a schedule, a webhook, or another app event, not just by hand.

Which apps can I connect?

Any of NoClick’s tool-provider integrations, from Slack and Linear to GitHub, Notion, Google Sheets, Postgres, and dozens more.

Codex

Connect Codex to Mailgun

Give an AI agent your Mailgun as a tool and it can act on your email infrastructure instead of just reporting on it. It can create domains and routes, spin up mailing lists and add members in bulk, build templates and new versions, and read metrics, events, and bounce lists to decide what to do next, calling each operation as a tool while it works. Wire it into a coding agent in NoClick and it can triage bounces, update unsubscribe lists, and keep templates current on its own.

What happens next

Set up in minutes

The open button drops you into a guided setup. It asks exactly this, nothing else:

Choose where it runs
On your computer through your own Codex, or hosted in the cloud. The rest of setup adapts to your choice:
Pick what it can do in Mailgun
A preset of real Mailgun operations. Each one becomes a tool the agent can call, and it can't touch anything outside the list.
Connect Mailgun
One sign-in. The agent acts through your account, scoped to the operations you picked.
Add your personal MCP link
The last step mints a private MCP URL for this agent and walks you through exactly this, with your real link filled in. The page flips to Connected the moment your Codex first calls in. Codex connects when a session starts — run codex, or restart a running one.
Run this in your terminal
$codex mcp add noclick --url https://mcp.noclick.app/s/<your-link>
<your-link> is your personal server URL — setup mints it for you.

Starting points

What you can build

When an email hard bounces, add the address to your unsubscribe list and remove that member from the relevant mailing list automatically.

On every inbound email caught by a route, fetch the stored message and hand it to an AI step that classifies it or drafts a reply.

When a new signup arrives from a form, add the address as a member to the right mailing list without a manual import.

Pull Mailgun metrics and event data on a schedule and post a daily deliverability summary to your team channel.

Bulk add a freshly imported list of contacts as members, then check the bounce list to prune bad addresses before the next send.

When an email is opened or clicked, log the engagement to your CRM and trigger a follow-up sequence.

About Codex

Codex is OpenAI's command-line coding agent. NoClick runs it as a hosted agent and lets you connect your apps to it as tools, turning it from a coding assistant into an operator that can act across your systems. Connect an integration to the agent and Codex can query, create, and update records in that app directly. You keep the Codex experience and give it real reach into the tools your team already uses.

Fast, capable code generation and editing

Good at well-scoped, concrete tasks

Strong at API and data manipulation

Familiar to teams already on OpenAI tooling

Good to know
