SendGrid is used by engineering and marketing teams for transactional and marketing email. Connecting it to OpenClaw gives your team delivery stats, bounce rates, and suppression list queries without leaving Slack.
How OpenClaw Integrations Work
OpenClaw is a self-hosted AI assistant that runs on your own server — typically an EC2 instance — and connects to Slack. It uses Claude under the hood to process requests. Out of the box, OpenClaw doesn't ship with pre-built connections to third-party tools. Instead, integrations are built using the skills system: markdown files in ~/.openclaw/skills/ that give Claude instructions for a particular domain, combined with HTTP tool calls to any API you expose to it.
In practice, adding a real integration means: getting API credentials from the third-party service, building or configuring a small proxy/endpoint that OpenClaw can call, and writing a skill file that tells Claude how to use it. For some tools this is an afternoon of work. For others — like SendGrid — it's considerably more involved.
Connecting OpenClaw with SendGrid: Step by Step
Step 1: Create a SendGrid API Key
In SendGrid, go to Settings → API Keys and create a restricted key. For read-only monitoring, grant access to Stats → Read, Email Activity → Read, and Suppressions → Read. The SendGrid Web API v3 base URL is https://api.sendgrid.com/v3/ and uses Bearer token authentication.
Step 2: Use the Stats and Activity Endpoints
Key endpoints: /stats?start_date=&end_date= (global send stats), /categories/stats (stats by category tag), /email_activity (individual email activity — requires Email Activity add-on), /suppression/bounces and /suppression/spam_reports for list hygiene queries.
Step 3: Build the Proxy and Skill File
Wrap the stats and suppression endpoints in a proxy. Write ~/.openclaw/skills/sendgrid.md documenting what metrics are available and at what time granularity. Note which category tags your team uses to segment sends — these are the most useful filters for day-to-day queries.
Challenges and Caveats
Email Activity Requires a Paid Add-On
The /email_activity endpoint — which lets you search individual email events — requires the Email Activity add-on, priced separately. Without it, you can only get aggregate stats, not per-recipient delivery data.
Stats Are Aggregated, Not Real-Time
SendGrid's stats API returns aggregated data, typically with a few hours' delay for the current day. For real-time send tracking you need Event Webhooks, which require a publicly accessible endpoint on your server to receive events.
