SendGrid is an email delivery platform by Twilio for transactional messages, marketing campaigns, and analytics at scale. Connect it to Rocket and describe the email flow you want in chat. Rocket generates the complete sending logic: templates, API calls, event tracking, and delivery management.
SendGrid excels at high-volume sending and marketing campaigns. For simpler developer-focused transactional email, Resend may be a lighter option. Pair with Supabase for user data and Stripe for payment-triggered emails.

​

​
Quick start

1

Get your SendGrid API key

Go to the SendGrid Dashboard, click Create API Key, give it a name, and copy the key. You also need to verify a sender identity under Settings > Sender Authentication.
2

Connect in chat

Open any Rocket project and type:
Connect SendGrid and send an order confirmation email when a user completes checkout.
Paste your API key when prompted. Rocket builds the email flow instantly.
3

Test the email

Trigger the flow in your app preview and check your inbox. Review delivery status in the SendGrid Activity Feed.
This connector is only available for Next.js TypeScript web build tasks.

​
Detailed setup

​
Get your SendGrid API key

Open SendGrid’s documentation to learn how to create your API key.
To generate an API key:
  1. Log in to SendGrid and go to Settings > API Keys.
  2. Click Create API Key.
  3. Add a name and choose permissions (Full Access or Restricted), then confirm.
  4. Copy the key. You will paste it into Rocket in the next step.
Never paste your SendGrid API key directly into Rocket chat. Always use the secure integration flow or the API key input in settings. If you believe your key has been exposed, revoke it from SendGrid Settings and create a new one.

​
Connect SendGrid to Rocket

There are two ways to connect SendGrid:Method 1: Use Rocket chat (fastest)In any project, open the chat panel and type:
  • Connect my SendGrid account to send a password reset email to users.
  • Connect SendGrid and set up order confirmation emails.
A popup appears where you can paste and save your API key.Method 2: From ConnectorsIn the preview toolbar, click the ... button and select Connectors. Click the SendGrid card.
When you connect SendGrid from Connectors, Rocket does not automatically create email flows. After saving your key, describe the email flow you want in chat.
Paste your API key into the field and click Save. A green dot appears next to SendGrid when the connection is active.Update or disconnectClick the SendGrid integration again. Replace the existing key or click Disconnect to remove it.

​
Tips and limitations

  • Verify your sender identity first. SendGrid requires domain authentication or single-sender verification before you can send emails. Complete this in SendGrid Settings before connecting.
  • No permanent free tier. SendGrid’s free plan allows 100 emails per day with no expiration. Upgrade for higher volume. Check SendGrid pricing for current plans.
  • Manage contacts in SendGrid. You can add subscribers through Rocket, but deleting contacts and managing suppression lists must be done in the SendGrid dashboard.
  • One SendGrid account per project. Each Rocket project connects to one SendGrid API key. Use different projects for different SendGrid accounts.
