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

  • Unified Messaging API: A single, channel-agnostic RESTful API to send messages across SMS, WhatsApp, iMessage, RCS, and Viber.
  • Intelligent Delivery Optimization: ML-powered algorithms automatically select the best channel and delivery time to maximize reach and minimize costs.
  • Message Schema Transformation: Automatically converts rich message formats (MMS, RCS, WhatsApp Templates) with graceful fallback to SMS for unsupported channels.
  • Fallback Management: Configure custom or automated cascading delivery logic with specific timeouts, retry attempts, and alternative channel routing.
  • Free Phone Number Lookup & Verification: An AI-powered tool and API to validate, format (E.164), and enrich phone numbers with carrier, CNAM, and fraud detection data. No API key required for the free tool.
  • Comprehensive Analytics: Real-time metrics on channel performance, delivery states, routing decisions, and costs per channel.
  • Developer-First Tools: SDKs in 5+ languages, detailed API logs, a sandbox testing environment, and a visual template editor.
  • Compliance and Number Management: Ensures use of official channels (10DLC, WhatsApp Cloud API), provides unified number provisioning, and monitors sender reputation.

Use Cases for Sent

Sent is versatile and can be applied across various industries for different communication needs. For e-commerce, it can be used for order confirmations, shipping notifications, and abandoned cart reminders. In marketing, it's ideal for sending promotional offers, discount codes, and running referral campaigns. For service-based businesses, it excels at sending appointment reminders, collecting customer feedback, and sending Google review requests. Financial institutions can use it for sending secure One-Time Passwords (OTPs) and payment reminders. Real estate agents can notify clients about new property listings that match their criteria. Essentially, any business that needs to send transactional or marketing messages to its customers can benefit from Sent's streamlined, multi-channel approach.

Advantages of Sent

The primary advantage of Sent is its significant cost reduction, achieved through intelligent, least-cost routing. By abstracting the complexity of multiple messaging APIs into one, it drastically reduces development time and maintenance overhead. The platform's focus on a superior developer experience, with excellent SDKs and debugging tools, allows teams to integrate and ship features faster. The AI-powered features, from delivery optimization to phone number validation, provide a layer of intelligence that improves campaign effectiveness and data quality. Furthermore, its commitment to 'White Route' compliance ensures high deliverability and protects sender reputation.
