How to Use OpenClaw with SendGrid — Automated Email Workflows

SendGrid is the go-to email API for production volume. With OpenClaw connected, you can send transactional emails, drip sequences, and bulk campaigns entirely from agent logic — no manual sending, no clunky dashboards.

Get Your SendGrid API Key

Log in to sendgrid.com, go to Settings → API Keys → Create API Key. Add it to your environment:

SENDGRID_API_KEY=SG.your_key_here
SENDGRID_FROM_EMAIL=hello@yourdomain.com
SENDGRID_FROM_NAME=Hex Agent

Install the SDK

npm install @sendgrid/mail

Basic Email Sending

const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);

await sgMail.send({
  to: userEmail,
  from: { email: process.env.SENDGRID_FROM_EMAIL, name: process.env.SENDGRID_FROM_NAME },
  subject: 'Your order is confirmed',
  text: 'Thanks for your order! It will ship in 2-3 days.',
  html: '
Thanks for your order! It will ship in 2-3 days.
'
});

Dynamic Templates

For branded emails, use SendGrid Dynamic Templates:

await sgMail.send({
  to: user.email,
  from: process.env.SENDGRID_FROM_EMAIL,
  templateId: 'd-abc123yourtemplateid',
  dynamicTemplateData: {
    first_name: user.firstName,
    product_name: 'The OpenClaw Playbook',
    download_link: 'https://openclawplaybook.ai/download'
  }
});

Drip Campaign Cron

{
  "name": "onboarding-drip",
  "schedule": "0 9 * * *",
  "task": "Check new users who signed up 1, 3, and 7 days ago. Send the welcome template to day-1 users, feature tips template to day-3 users, and upgrade nudge to day-7 users."
}

Webhook Handling

Set your SendGrid Event Webhook to your gateway endpoint. Your agent handles bounce, open, click, and unsubscribe events automatically — updating your CRM on unsubscribes, alerting on high bounce rates, and triggering re-engagement flows on inactivity.

Monitoring Deliverability

{
  "name": "email-health-check",
  "schedule": "0 8 * * *",
  "task": "Pull SendGrid stats for yesterday. If bounce rate exceeds 2% or spam rate exceeds 0.1%, send a Slack alert to #ops immediately."
}
