Quickstart · Rust

Send transactional email through Envimaily's HTTP API (https://api.envimaily.com) with Rust.

1. Account & key

1. Sign up at https://app.envimaily.com/dev/signup
2. Create an em_ key under API keys
3. Copy the token once — it is not shown again

2. Example

// reqwest
let client = reqwest::Client::new();
let res = client
  .post("https://api.envimaily.com/v1/emails")
  .bearer_auth("em_YOUR_KEY")
  .json(&serde_json::json!({
    "from": "onboarding@envimaily.com",
    "to": ["you@example.com"],
    "subject": "Hello from Rust",
    "html": "<p>It works.</p>"
  }))
  .send()
  .await?;
println!("{}", res.text().await?);

3. Without a verified domain

Use the shared test sender onboarding@envimaily.com and send only to the account owner email. After SPF/DKIM verification, send from your domain.

4. Limits
