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

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.
