About Sendblue

Sendblue is a business communication platform that leverages Apple's iMessage infrastructure to enable personalized, high-response-rate messaging. The platform offers an API and a set of tools for sending iMessages, including multimedia content such as voice memos, videos, and high-resolution photos. Sendblue also supports FaceTime Audio for voice calls and group chats, all while maintaining compliance with regulations like SOC 2 Type II and HIPAA. The service is designed for businesses seeking to improve customer engagement, sales conversions, and support workflows through trusted, familiar messaging channels. It integrates with popular CRMs via a Chrome extension and custom-built connections, and provides workflow automation and a power dialer (Smart Views). Sendblue emphasizes transparent flat monthly pricing based on phone lines, with no hidden carrier fees, and does not require the lengthy A2P registration process typical for SMS marketing. A free starter tier is available without a credit card, though exact limits should be verified on the pricing page. The platform is suited for sales teams, customer support, marketing, and AI-driven outreach agents, with a reported track record of over $2.1 billion in revenue generated by its users.
