UniSender is a simple and easy-to-use service for email and SMS marketing campaigns.. Once connected, OpenClaw can read and act on Unisender from chat — pairing, token refresh, and tool wiring handled for you.

33 tools

The usual route to Unisender access for OpenClaw is an MCP server you configure and keep running, plus your own OAuth app or API keys. ClawLink gives OpenClaw a more practical Unisender setup: install one ClawHub skill, connect Unisender in the browser, and OpenClaw can call real Unisender actions from any chat surface with no auth, token refresh, or tool wiring to build yourself.

Setup

It takes three steps to connect OpenClaw to Unisender.

  1. 1

    Install the plugin

    Paste the setup prompt into OpenClaw, or install from the terminal and ask OpenClaw to pair:

    openclaw plugins install clawhub:clawlink-plugin
  2. 2

    Connect Unisender

    Paste your API key in the dashboard.

  3. 3

    Use it from chat

    Ask OpenClaw: "What can you do with Unisender?"

Install by command

The setup prompt above does all of this in one paste. By hand, it is one install command plus a browser approval:

openclaw plugins install clawhub:clawlink-plugin

Then ask OpenClaw to set up ClawLink. It starts browser pairing and prints an approval link — open it, approve the device, return to the chat, and say done. Finally, connect Unisender in the ClawLink dashboard — paste your Unisender API key once.

Verify the connection by asking OpenClaw:

Use Unisender to check email and walk me through the result in plain English.

Using a different agent?

The OpenClaw plugin is one client of ClawLink's MCP server. Claude Code, Cursor, Codex, or any agent that can run a shell command pairs with the same ClawLink account through the CLI:

npx -y @useclawlink/cli login

login opens the same browser approval and stores a credential locally. Once Unisender is connected in the dashboard, that agent calls the same 33 Unisender tools over MCP. Full setup for MCP clients and shell agents: connect apps to any AI agent.

The alternative to ClawLink is usually manual API key setup plus your own token handling, permission troubleshooting, and tool plumbing for OpenClaw. That is fine if you want to build and maintain the integration yourself. Most teams just want Unisender working from chat.

Credential handlingCollect, validate, store, and rotate the Unisender API key yourself, then make sure every tool call uses the right account.Users complete the hosted ClawLink setup once and the connected Unisender account becomes available to the agent without you building credential management.
Ongoing maintenanceYou own refresh logic, permission debugging, environment config, and every provider-specific edge case for Unisender.ClawLink handles the repetitive integration plumbing so your team can focus on the workflow instead of the infrastructure.
Agent usabilityYou still need to expose the right Unisender actions to the runtime in a format your agent can reliably use.33 tools for Unisender are already exposed through ClawLink, so the agent can read and act from chat immediately.

Composio also exposes Unisender to AI agents. It is developer infrastructure: Python and TypeScript SDKs, an MCP server, and a catalog past 1,000 apps, aimed at teams shipping agent products. ClawLink is built for OpenClaw users instead. You install the plugin once, connect Unisender in the browser, and the 33 tools above work from chat. There is no SDK and no config file, and the Unisender key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

Troubleshooting

OpenClaw installed the Unisender skill but can't call the tools

The ClawHub skill teaches OpenClaw about Unisender, but the calls run through the ClawLink plugin and your connected account. Make sure Unisender is connected in the dashboard, then start a fresh chat so OpenClaw reloads the tool catalog. If OpenClaw runs as a persistent gateway, restart it so the new tools register.

Connection succeeds but no tools appear

Reconnect Unisender from the dashboard, then start a fresh chat if the runtime still has the old tool catalog loaded.

"Tool schema not loaded yet" error when calling Unisender tools

Unisender tool schemas load on demand the first time a tool runs and are cached after that, so this error usually clears on its own: wait a few seconds and retry the same request. If every Unisender call keeps failing with it in a fresh chat, reconnect from the dashboard, and contact support if it still persists — that pattern points to a configuration problem on our side, not something you can fix by reconnecting again.

Unisender returns 403 or "permission denied" on one action while others work

Two usual causes. The connected account may not have access to the specific workspace, inbox, store, or project in the request — check that first. If access looks right, the agent may have sent a placeholder value (like "YOUR_ID" or an example id from documentation) instead of a real one: ask it to run a list or search tool first, then retry the action with a real id from those results. Most failures at this stage are one of these two, not ClawLink bugs.

API key setup works but results look incomplete

Double-check that the API key for Unisender has the right scopes or account access. A valid key can still be too limited for some reads or writes.
