What is Sendmux?
Sendmux offers specialized inboxes for AI agents along with an efficient framework for email communication. Each agent can handle incoming messages, assess conversation threads, organize attachments, respond to emails, and interact with new mail via signed webhooks or Server-Sent Events.
Teams have the option to send emails using various methods, including Gmail OAuth, Outlook OAuth, SMTP services, or managed Amazon SES, providing them with flexibility in their email operations. Furthermore, Sendmux allows for the distribution of email sending across multiple providers through features like weighted routing, sender-domain routing, health checks, failover strategies, and customizable quotas that can be set for different timeframes such as seconds, minutes, hours, or days.
Developers benefit from a suite of tools including Mailbox, Sending, and Management APIs, extensive OpenAPI documentation, SDKs, the sendmux CLI, and MCP utilities, along with Sendmux Skills. Additionally, the system guarantees tenant isolation, offers mailbox-specific API keys, accommodates custom domains, and features robust logging and metrics, all while adhering to a usage-based pricing structure that avoids charging per seat or mailbox. This thorough design not only streamlines email management for teams and developers but also enhances their overall communication efficiency. By prioritizing flexibility and functionality, Sendmux positions itself as a pivotal tool in the landscape of email communication solutions.
