Email API for transactional sending and agent workflows

SendHQ is an email API rather than a marketing tool. It handles verified-domain transactional sending, inbound email, delivery event tracking and scoped API keys, with observability built around AI agent workflows. The pitch is that a product or agent team can send, receive and inspect email in one place with workspace-level key management. Paid only, from 9 USD a month, with no free tier.

Our verdict

A developer product, not a marketer one. Worth knowing about if you are building an AI agent that needs to send or receive email, but it sits well outside what most marketing teams would touch.

Best for: Marketing ops and product teams with developer resource who need programmable transactional email inside an AI agent workflow.

Pros

• Handles outbound and inbound email in one API, so an agent can act on replies rather than just send
• Delivery event tracking is built in, giving you visibility on what actually landed
• Scoped, workspace-level API keys are a sensible security default for teams running multiple projects
• Starts at 9 USD a month, which is cheap for programmable email infrastructure

Cons

• Implementation needs developer resource, so it is not something you can set up from a dashboard
• No free tier or trial, so evaluating it starts at 9 USD a month

Pricing: $9/mo (Paid)
