Sendblue

Sendblue is an AI chat bot tool. Sendblue enables businesses to send iMessage, SMS, and RCS from their CRM or via REST API, with no A2P registration. It combines a shared inbox, workflow automation, and developer tools for building AI agents on iMessage.

Sendblue is a business messaging platform that routes communication through iMessage rather than traditional SMS. It combines a shared team inbox, workflow automation, and a REST API so companies can reach customers on the channel many people check first. The pitch is straightforward: when a message arrives as a blue bubble instead of a green one, recipients treat it as personal correspondence rather than a bulk alert, which the company claims produces two to three times higher response rates than SMS. For sales teams, the product works as a layer on top of existing CRM tools. Reps send iMessages directly from Salesforce, HubSpot, or other connected systems, and incoming replies land in a shared inbox. Built-in features include a workflow builder, smart views, a power dialer, group chats, and support for voice memos, video, and high-resolution photos. Setup is quick: sign up, provision a phone number, and start sending. There is no lengthy A2P registration process, which removes roughly two to three weeks of carrier paperwork. Developers can use the same infrastructure to build AI agents on iMessage. The API lets you send and receive messages programmatically, and the CLI provides a way to provision numbers and deploy agents from the terminal. Examples on the site include a sales assistant that books meetings and a personal agent that can research flights and make bookings. The underlying message is that iMessage can serve as a conversational interface for AI, not just a sales channel. The platform is SOC 2 Type II certified and offers HIPAA-compliant plans, which matters for teams handling sensitive data. Pricing is flat per phone line, with no hidden carrier fees or message segment charges. The site reports over 20,000 businesses and more than 35,000 installs, with customers that include Bilt, ClickFunnels, and the U.S. Army. Support includes strategic account managers and vertical-specific frameworks through a service called The Blueprint. Sendblue competes less with traditional SMS gateways and more with the broader category of customer engagement platforms, distinguishing itself through the iMessage channel and a developer-friendly API.
