# Paubox Go SDK

> Send HIPAA-compliant email and submit Paubox Forms from Go applications using the official Paubox Go SDK.

The Paubox Go SDK is the official Go client library for the [Paubox Email API](/email-api) and [Paubox Forms](/forms). It provides a type-safe, idiomatic Go interface for sending encrypted email, managing dynamic templates, tracking delivery, and submitting forms — with no external dependencies.

```bash theme={null}
go get github.com/paubox/paubox-go
```

## What you can do

* Send encrypted, HIPAA-compliant email to one or more recipients
* Send batches of up to 50 messages in a single API call
* Track delivery status and open/click engagement per recipient
* Create, update, and delete dynamic Handlebars templates
* Send templated messages with per-message variable substitution
* Retrieve Paubox Form schemas and submit form responses with file attachments
* Configure automatic retries with exponential backoff and jitter

## Requirements

* **Go** 1.22 or later
* No external runtime dependencies — the SDK uses only the Go standard library
