Email API गाइड

An email API lets your application send emails through simple HTTP requests. It’s faster, more reliable, and more feature-rich than SMTP, the standard choice for modern applications.

Email API vs SMTP

Best Email APIs Compared

Quick Start: Sending Email via API

Brevo API Example

curl --request POST \
  --url https://api.brevo.com/v3/smtp/email \
  --header 'api-key: YOUR_API_KEY' \
  --header 'content-type: application/json' \
  --data '{
    "sender": {"name": "Your App", "email": "[email protected]"},
    "to": [{"email": "[email protected]", "name": "User"}],
    "subject": "Welcome!",
    "htmlContent": "<h1>Welcome to our app!</h1><p>Thanks for signing up.</p>"
  }'

When to Use Email API

Transactional Emails

• Welcome emails on signup
• Password reset links
• Order confirmations
• Shipping notifications
• Account alerts

Marketing Emails (via API)

• Automated campaigns
• Personalized emails based on app events
• Drip sequences triggered by user behavior

Key API Features to Look For

1. Webhooks, Real-time notifications for opens, clicks, bounces
2. Templates, Reusable email templates with variable substitution
3. Rate limiting, High enough for your volume needs
4. Analytics, Open, click, bounce, and delivery tracking
5. Inbound parsing, Process incoming emails
6. Suppression management, Automatic bounce and complaint handling

Deliverability with API

Same rules apply as any email sending:

• Authenticate your domain (SPF, DKIM, DMARC)
• Warm up new sending domains gradually
• Monitor bounce rates and complaints
• Use dedicated IPs for high volume
