guerrillamail-client 0.7.2

An async Rust API client for the GuerrillaMail temporary email service. This crate lets you programmatically create disposable email addresses, poll inboxes, and fetch message contents using an idiomatic async Rust API built on tokio and reqwest.

When to use this

• Email-based testing (signups, verification emails, password resets)
• Automation and scraping workflows
• CI / integration tests that need a disposable inbox
• Account generators and security tooling

Features

• Async/await first — built on tokio and reqwest
• Create temporary email addresses
• Poll inbox messages
• Fetch full email contents
• Forget/delete addresses
• Proxy support (e.g. Burp, mitmproxy)
• Configurable TLS + User-Agent
• Well-typed errors with proper chaining

Installation

Add to your Cargo.toml:

[dependencies]
guerrillamail-client = "0.7.1"
tokio = { version = "1", features = ["full"] }

Quick start

use guerrillamail_client::Client;

#[tokio::main]
async fn main() -> Result<(), guerrillamail_client::Error> {
    // Create a client (performs a bootstrap request)
    let client = Client::new().await?;

    // Create a temporary email address
    let email = client.create_email("myalias").await?;
    println!("Temporary email: {email}");

    // Poll inbox
    let messages = client.get_messages(&email).await?;
    for msg in messages {
        println!("From: {}", msg.mail_from);
        println!("Subject: {}", msg.mail_subject);
    }

    // Fetch full email body
    if let Some(msg) = messages.first() {
        let details = client.fetch_email(&email, &msg.mail_id).await?;
        println!("Body:\n{}", details.mail_body);
    }

    // Forget the email address
    client.delete_email(&email).await?;

    Ok(())
}

Downloading attachments

use guerrillamail_client::Client;

#[tokio::main]
async fn main() -> Result<(), guerrillamail_client::Error> {
    let client = Client::new().await?;
    let email = client.create_email("myalias").await?;
    let messages = client.get_messages(&email).await?;

    if let Some(msg) = messages.first() {
        let attachments = client.list_attachments(&email, &msg.mail_id).await?;
        if let Some(attachment) = attachments.first() {
            let bytes = client
                .fetch_attachment(&email, &msg.mail_id, attachment)
                .await?;
            println!("Downloaded {} bytes", bytes.len());
        }
    }

    Ok(())
}

Configuration via builder

For proxies, stricter TLS, custom user agents, or a different request timeout, use the builder API:

use guerrillamail_client::Client;

let client = Client::builder()
    .proxy("http://127.0.0.1:8080")
    .danger_accept_invalid_certs(false)
    .user_agent("my-app/1.0")
    .timeout(std::time::Duration::from_secs(30)) // default is 30s; customize as needed
    .build()
    .await?;
