# Introduction

Welcome to SendX API Documentation.

You can use SendX API to automate all aspects of email marketing and marketing automation.

Common use-cases include:

* Adding contacts with custom data and tags
* Push custom events or revenue event for a contact
* Sending transactional emails

Note that you can use the contact custom data pushed for personalisation and segmentation of your audience. You can use custom events to trigger visual workflows or automation rules.

Advanced use-cases include:

* Creating and scheduling dynamic email campaigns
* Consuming webhooks and campaign reports to craft custom dashboards
