- Teams testing email-heavy software and AI agents
- Worth noticing
- It lists SMTP, IMAP, an API, and MCP as connection paths, while stating that messages never reach real inboxes.
Field notes
The workflow starts by pointing an app at simmail, then inspecting mail and simulated recipient activity in a dashboard. The page describes personas that may open, ignore, click, research a sender, remember prior exchanges, and reply on their own schedule; teams can also trigger greylisting, rate limits, bounces, and provider failures. SMTP, IMAP, an API, and MCP are listed as connection paths, while the site says no message reaches a real inbox.
