# Getting Started with Transactional Email

Follow these steps to set up and start using our Transactional Email API:

## 1. Add Your Domain

First, you need to add and verify your domain:

1. Log in to our Dashboard ([https://dash.jetemail.com](https://dash.jetemail.com))
2. Navigate to the "Outbound" section
3. Click on "Domains"
4. Click Add and enter your domain name.

## 2. Authenticate Your Domain

After adding your domain, you'll need to set up authentication using SPF, DKIM, and DMARC records:

1. In your domain settings, you'll find the generated SPF, DKIM, and DMARC records
2. Add these records to your domain's DNS settings:
   * SPF (Sender Policy Framework)
   * DKIM (DomainKeys Identified Mail)
   * DMARC (Domain-based Message Authentication, Reporting, and Conformance)
3. Wait for the records to propagate (this can take up to 24 hours)
4. Once propagated, the records will show up as verified.

## 3. Create a Transactional API Key

To use our API, you'll need to generate an API key:

1. Go to the "Keys" section under Outbound.
2. Click on "Add API Key"

3. Name your key (e.g., "Transactional Email Key")
4. Copy and securely store the generated API key.

## 4. Send Emails Using Our API, SDK, or Plugins

You can send via the **REST API** ([API reference](/api-reference/introduction)), the **[Node.js SDK](/transactional-email/sdk/nodejs)** ([jetemail on npm](https://www.npmjs.com/package/jetemail)), or a **plugin** (e.g. [WordPress](/transactional-email/plugins/wordpress)).
