Description

Dead Simple Email offers an email API that provides genuine email inboxes for AI agents and automated workflows. With just a single API call, users can set up an inbox and communicate using real email addresses via REST or standard IMAP/SMTP protocols, while receiving replies formatted as structured webhooks. Incoming messages undergo a prompt injection check prior to delivery, and users can access a dashboard that displays the complete history of communications for each agent. The service begins with a free plan that includes 5 inboxes, with an option to upgrade to 100 inboxes for $29 per month, charging based on the number of inboxes rather than the number of users. This flexibility makes it an appealing choice for businesses looking to integrate email functionality seamlessly into their automated systems.

Description

Sendmux provides AI agents with dedicated inboxes and a streamlined method for sending emails. Each agent is capable of receiving communications, reviewing conversation threads, managing attachments, replying to messages, and reacting to incoming mail through signed webhooks or Server-Sent Events. Teams can utilize various sending methods including Gmail OAuth, Outlook OAuth, SMTP providers, or managed Amazon SES, allowing for flexibility in their email communications. Additionally, Sendmux offers the ability to distribute sending across different providers using features like weighted routing, sender-domain routing, health checks, failover mechanisms, and customizable quotas based on time intervals such as seconds, minutes, hours, or days. For developers, the platform includes Mailbox, Sending, and Management APIs, comprehensive OpenAPI documentation, SDKs, the sendmux CLI, and MCP tools, along with Sendmux Skills. Moreover, the system ensures tenant isolation, provides mailbox-scoped API keys, supports custom domains, and includes logging and metrics, all while maintaining a usage-based pricing model without imposing fees for each seat or mailbox. This comprehensive approach enhances the overall email management experience for teams and developers alike.
