What does Sendly do?
Sendly is an SMS messaging API built specifically for developers. It lets you programmatically send text messages to users anywhere in the world. You can integrate it directly into your applications to handle notifications, authentication codes, appointment reminders, and other time-sensitive communications. The service manages carrier connections and delivery infrastructure so you can focus on building your product.
The platform provides a straightforward REST API that developers can implement quickly. It supports alphanumeric sender IDs for brand recognition and toll-free numbers for US/Canada messaging. Sendly handles rate limiting and delivery optimization automatically, which helps maintain good deliverability rates. The service includes built-in compliance features like opt-out management and content filtering to help users adhere to telecommunications regulations.
Sendly works best for development teams building applications that require reliable SMS communication. Common use cases include sending two-factor authentication codes during login, shipping notifications for e-commerce platforms, and appointment confirmations for service businesses. It's also useful for startups that need to automate customer communications without building their own SMS infrastructure from scratch.
