SendGrid skill for OpenClaw

What this skill does

SendGrid API integration with managed OAuth. Send emails, manage contacts, templates, suppressions, statistics, sender identities, unsubscribe groups, and SendGrid API keys. All write operations require explicit user approval. Sending emails delivers messages to real recipients — confirm audience, content, and sender before executing. API key management creates long-lived credentials that persist beyond the session — only use when explicitly requested. Use this skill when users want to send transactional or marketing emails, manage email lists, handle bounces/unsubscribes, or analyze email performance. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). Requires network access and valid Maton API key. Calls run through the `maton` CLI with OAuth login, or over raw HTTP with a Maton API key where the CLI cannot be installed. Every call is authenticated as the user's connection and reaches only what that connection's authorization allows, which the provider enforces on every request; the endpoints documented here are the ones this skill uses, and any other endpoint of this app needs the user to ask for it by name. Default to read and list calls, and confirm every write or new connection with the user. This file also documents the three constructs that turn a SendGrid connection into automation, in the order they are used: the connection (the first step), a hosted function that runs a SendGrid action through the Maton SDK, and a trigger that calls that function on a schedule or on an event. Those sections are the platform's own reference text, shared with the api-gateway skill, with SendGrid examples; they add no SendGrid capability - SendGrid is not an event source, a trigger cannot read SendGrid data, and the files under `references/<source>/triggers.md` are the platform's event catalogues for the sources Maton offers (time, Calendly, GitHub, Gmail, HubSpot, Linear, Notion, Slack, Stripe).

The SendGrid skill is part of the Developer Tools category — developer tools that help your agent write, review, debug, and ship code. You can install it on its own or alongside other developer tools skills from the OpenClaw catalog.

How to install the SendGrid skill

The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:

1. Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
2. Open the in-app Skills panel.

Install from the command line

This pulls sendgrid from ClawHub and installs it into ~/.openclaw/skills/sendgrid/. Restart the OpenClaw gateway afterwards so the new skill is discovered.

How to use the SendGrid skill

Once installed, the SendGrid skill activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.

Manual install (advanced)

If you prefer manual installation:

1. Click the Download skill .zip button above to grab sendgrid-1.2.7.zip directly from our S3 mirror.
2. Unzip into ~/.openclaw/skills/sendgrid/ (create the directory if it does not exist).
