# Plunk Email SDK

A simple Rust SDK for sending transactional emails using the Plunk API.

Setup

1. Add dependencies to your Cargo.toml:

[dependencies]
reqwest = "0.12.15"
tokio = "1.44.2"
serde = "1.0.219"
common_manifold = "0.1.0"
dotenv = "0.15.0"

2. Create a .env file with your credentials:

PLUNK_PRIVATE_KEY=your_plunk_api_key_here

Quick Start

use plunk::prelude::{
    PlunkClient,
    PlunkClientTrait,
    PlunkPayloads,
};

// Initialize the client
let plunk_key = env::var("PLUNK_PRIVATE_KEY").expect("Set PLUNK_PRIVATE_KEY in .env");
let client = PlunkClient::new(plunk_key);

// Create an email payload
let payload = PlunkPayloads {
    to: "recipient@example.com".to_string(),
    subject: Some("Hello! 👋".to_string()),
    body: "Your email content here".to_string(),
};

// Send the email
match client.send_transactional_email(payload).await {
    Ok(msg) => println!("{}", msg),
    Err(err) => eprintln!("Error sending email: {}", err),
}

API Reference

PlunkClient

Initialize a new Plunk client:

let client = PlunkClient::new(plunk_key);

PlunkPayloads

Structure for creating email payloads:

Sending Emails

The send_transactional_email function returns a Result with either a success message or an error:

async fn send_transactional_email(payload: PlunkPayloads) -> Result<String, Error>

Error Handling

The SDK handles two main types of errors:

• Environment variable errors (missing API key)
• Email sending failures

Always wrap the email sending operation in a proper error handling block:

match client.send_transactional_email(payload).await {
    Ok(msg) => println!("Success: {}", msg),
    Err(err) => eprintln!("Error: {}", err),
}
