Flinkk Mail vs Resend
Resend is an email API with an official MCP server. Flinkk Mail is an email platform built around shared inboxes that AI agents can work in, with a person approving what they send. This is how the two compare on what each publishes.
The main difference
Flinkk Mail's agent access is built around approval: drafts wait for a person by default, each inbox has its own permissions and limits, and every action is logged. Resend's agents page describes giving an agent API-key access to its whole platform through MCP.
