# Mailtrap > Mailtrap is an email platform for developers and product teams: > send transactional and bulk emails via Email API/SMTP, > run marketing campaigns with Email Marketing, > test emails safely in Email Sandbox, and > automate email workflows with AI agents. ## Products - **[Email API/SMTP](https://docs.mailtrap.io/email-api-smtp/overview.md)** — Email sending infrastructure. Supports transactional and bulk email streams via REST API or SMTP, with email templates, real-time analytics, deliverability tools (SPF/DKIM/DMARC, dedicated IPs, suppression lists), webhooks, and email logs. - **[Email Sandbox](https://docs.mailtrap.io/email-sandbox/overview.md)** — Safe email testing environment for development and QA. Captures outgoing emails without delivering them, with HTML validation, spam score checking, bounce simulation, and load testing — so bugs are caught before emails are delivered. - **[Email Marketing](https://docs.mailtrap.io/email-marketing/overview.md)** — Campaign creation, scheduling, and analytics for marketing emails. Includes contact management, list segmentation, automation sequences, and campaign performance tracking. ## Getting Started - [Documentation Home](https://docs.mailtrap.io/readme.md): Complete email infrastructure overview - [Complete docs index](https://docs.mailtrap.io/llms.txt): Full documentation catalog for deep ingestion - [AI Onboarding](https://docs.mailtrap.io/getting-started/ai-onboarding.md): Onboard an AI agent to Mailtrap in minutes - [Email API/SMTP Quickstart](https://docs.mailtrap.io/getting-started/email-api-smtp.md): Send production emails from your app - [Email Sandbox Quickstart](https://docs.mailtrap.io/getting-started/email-sandbox.md): Test and debug emails safely before going to production - [Email Marketing Quickstart](https://docs.mailtrap.io/getting-started/email-marketing.md): Set up and send email marketing campaigns ## Email API & SMTP - [Overview](https://docs.mailtrap.io/email-api-smtp/overview.md): Key features, use cases, and how the sending infrastructure works - [Setup & Configuration](https://docs.mailtrap.io/email-api-smtp/setup.md): Get API credentials and start sending in minutes - [Sending Domain Setup](https://docs.mailtrap.io/email-api-smtp/setup/sending-domain.md): Verify your domain with SPF, DKIM, and DMARC - [API Integration](https://docs.mailtrap.io/email-api-smtp/setup/api-integration.md): Send via REST API with SDK and code samples - [SMTP Integration](https://docs.mailtrap.io/email-api-smtp/setup/smtp-integration.md): Send via SMTP credentials - [Bulk Stream](https://docs.mailtrap.io/email-api-smtp/setup/bulk-stream.md): Send promotional or bulk emails with compliance features - [Email Templates](https://docs.mailtrap.io/email-api-smtp/email-templates.md): Build templates with drag-and-drop editor or HTML;
