Key Features

1. Send Transactional Emails

import { sendEmail } from '@/lib/sendgrid/client'

await sendEmail({
  to: '[e-mail]',
  subject: 'Welcome to our app!',
  text: 'Thanks for signing up.',
  html: '<strong>Thanks for signing up!</strong>',
})

2. Use Email Templates

import { sendWelcomeEmail } from '@/lib/sendgrid/templates/welcome'

await sendWelcomeEmail({
  to: '[e-mail]',
  name: 'John Doe',
  loginUrl: 'https://app.example.com/login',
})

3. Send Notifications

import { sendNotificationEmail } from '@/lib/sendgrid/templates/notification'

await sendNotificationEmail({
  to: '[e-mail]',
  title: 'New Message',
  message: 'You have received a new message.',
  actionUrl: 'https://app.example.com/messages',
  actionText: 'View Message',
})

4. Batch Email Sending

import { sendBulkEmail } from '@/lib/sendgrid/client'

await sendBulkEmail({
  to: ['[e-mail]', '[e-mail]'],
  subject: 'Newsletter',
  html: '<p>Monthly newsletter content</p>',
})

Email Templates

Welcome Email

Professional welcome email with call-to-action button.

Notification Email

Generic notification template for alerts and updates.

Custom Templates

Create custom templates following the same pattern:

export async function sendCustomEmail(params: {
  to: string
  // ... custom params
}) {
  return sendEmail({
    to: params.to,
    subject: 'Custom Subject',
    html: generateHtmlTemplate(params),
  })
}

Security Best Practices

• Never expose API keys client-side
• Validate recipient email addresses
• Implement rate limiting
• Use unsubscribe links
• Handle bounces and spam reports

Testing

Test Mode

SendGrid provides a sandbox mode for testing:

const client = sendgrid()
client.setApiKey(process.env.SENDGRID_API_KEY!)
client.setSandboxMode(true) // Enable sandbox

Email Validation

Always validate emails before sending:

import { isValidEmail } from '@/lib/sendgrid/utils'

if (!isValidEmail(email)) {
  throw new Error('Invalid email address')
}
