ChelaMail launches agent email API

This is the right kind of infrastructure for agent products: email is a workflow primitive, but it is also a security hazard, so the mailbox itself has to defend against untrusted content. ChelaMail’s strongest angle is treating prompt injection as an inbox problem instead of a post-processing problem.

• –MCP support lowers integration friction for agent stacks that want mailbox actions exposed as tools.
• –Suspicious-email quarantine is the most meaningful feature here, because inbound email is a classic prompt-injection vector.
• –Self-registration plus USDC-on-Base payments points to autonomous provisioning and bot-friendly commerce.
• –Free unlimited inbound is a smart wedge, while outbound pricing gives the product a simple usage-based monetization path.
• –The category is getting crowded fast, so reliability, deliverability, and search quality will matter more than the pitch.
