Sent Overview
Sent offers a revolutionary approach to business messaging with its unified API, the Sent One API. This platform is designed to abstract the complexities of A2P (Application-to-Person) messaging, allowing businesses to focus on building their products rather than wrestling with multiple messaging service integrations. By integrating a single RESTful API, developers can reach customers on their preferred channels, including SMS, WhatsApp, iMessage, RCS, and Viber. Sent's core value proposition lies in its intelligent delivery model, which leverages machine learning to select the most effective and cost-efficient channel for each message, claiming to reduce messaging costs by up to 80-90%.
The platform is not just a message dispatcher; it's a comprehensive communication suite. It automatically handles message schema transformations, converting rich content (like MMS or WhatsApp Templates) into formats compatible with simpler channels like SMS, ensuring a seamless user experience. It also includes robust tools for developers and marketers, such as a free AI-powered phone number lookup and validation service, a visual template editor, and a sandbox environment for thorough testing.
How to use Sent
Integrating and using Sent is designed to be straightforward for developers. The process begins with signing up to get API access, which includes $25 in free credits and a complimentary phone number for testing. Developers can then integrate Sent's API into their applications using SDKs available for over five popular programming languages. Sending a message is as simple as making a single API call to a channel-agnostic endpoint. Sent's system then takes over: it uses its Channel Availability Detection to determine which channels the recipient uses, selects the optimal channel based on ML-powered delivery optimization, transforms the message content if necessary, and sends it. The platform provides real-time event notifications via webhooks for events like 'message.delivered', 'message.read', and 'message.click', allowing for detailed tracking and automation.
Core Features of Sent
