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
SubsiMail is a platform for self-hosted cold email sequencing, allowing users to manage prospect lists, templates, connected inboxes, and all campaign-related data directly within their own database rather than relying on a third-party SaaS solution. Designed as an alternative to platforms like Instantly, Smartlead, lemlist, and Apollo, it offers flat pricing based on connected inboxes instead of per-seat charges, ensuring complete ownership and export of data without any content review processes or external access to contacts and campaigns. The application operates seamlessly as a single Docker container on any $5 VPS, enabling users to connect to Gmail, Outlook, or any SMTP/IMAP inbox, create multi-step email sequences that incorporate merge fields and reply detection, manage user roles (admin, manager, view-only) while maintaining a comprehensive audit trail, and utilize integration through a REST API secured by personal API keys. Furthermore, the initial connected mailbox comes with a perpetually free option, making it an attractive choice for individuals and businesses alike. This unique setup empowers users with greater control over their email marketing campaigns while simplifying the management process.
