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.

Description

SuperMailOS provides managed business email services on your own domain, specifically designed for small teams. You simply provide your domain while SuperMailOS takes care of the mail server and ensures optimal deliverability through SPF, DKIM, DMARC, IP reputation management, and warmup, guaranteeing that your emails reach the inbox instead of being marked as spam. The setup process is quick and user-friendly; you can verify your domain in seconds using one-click DNS with platforms like Cloudflare and DigitalOcean, or follow simple copy-paste instructions with any registrar, then invite your team members and begin sending emails immediately. Each user receives a genuine mailbox, with the added benefit of unlimited and free aliases, such as hello@ and support@. The webmail interface is designed to be as intuitive as Gmail, featuring threaded conversations, instant search capabilities, keyboard shortcuts, labels, and dark mode, alongside support for IMAP and SMTP, enabling compatibility with any email application. Additionally, SuperMailOS provides a real-time deliverability dashboard to monitor where your emails land. Pricing is straightforward with a flat rate per mailbox: the Pro plan costs $3 per month when billed annually and includes 10 GB of storage and three domains, while the Business plan is priced at $5 per month, offering 30 GB of storage and unlimited domains, along with customizable options for larger teams of 50 or more. A 14-day free trial is available with no credit card required, allowing you to experience the service risk-free.
