## Overview

- **Who it's for**: Developers and product teams who need to send transactional and bulk emails from their applications, and to receive/parse inbound email, without running their own mail infrastructure.
- **What you get**: An Email Sending product (branded Email API/SMTP) offering a REST API and SMTP relay for sending, hosted HTML email templates with Handlebars variables, deliverability tooling (SPF/DKIM/DMARC, dedicated IPs on higher tiers, suppression and bounce handling), webhooks for delivery events, analytics and searchable email logs, inbound email parsing, and official SDKs for Node.js, Python, PHP, Ruby, Java, .NET, and Elixir. Mailtrap also sells a separate Email Testing/Sandbox product and an Email Marketing product with their own pricing.
- **How it works**: Applications authenticate with an API token and send either via a POST request to the transactional REST API (send.api.mailtrap.io) or via SMTP relay (live.smtp.mailtrap.io:587), optionally referencing a template by UUID instead of inline HTML. Sent messages generate real-time analytics, logs, and webhook events, and a separate inbound-email endpoint lets applications receive and parse incoming mail via API or webhook.
