API FAQ

Common questions about our Email API service.

We provide official SDKs for JavaScript/Node.js, Python, Ruby, PHP, Java, and Go. Our REST API can be used directly from any language that can make HTTP requests. Community-maintained SDKs are also available for other languages.

We maintain strong relationships with major email providers and continuously monitor our sending reputation. Our system automatically handles bounce management, complaint feedback loops, and implements best practices for authentication (SPF, DKIM, DMARC). We also provide tools to monitor and improve your own domain reputation.

Yes, our API supports attachments up to 10MB in size. You can either include the file data directly in your API request (base64 encoded) or provide a URL where we can fetch the file from. Supported file types include PDFs, images, Word documents, and more.

Webhooks allow you to receive real-time notifications about email events (deliveries, opens, clicks, bounces, etc.). You can register multiple webhook endpoints in your dashboard, and we'll send HTTP POST requests to these URLs whenever events occur. Each webhook payload includes detailed information about the event.

Our API has a default rate limit of 100 requests per second for sending emails and 300 requests per second for other endpoints. Higher limits are available for enterprise plans. If you exceed the limit, you'll receive a 429 Too Many Requests response.
