What it does

About SendHQ

SendHQ gives product teams and AI agents one coherent email workflow for serious product communication. Teams can verify sending domains, send transactional messages through an email API, receive inbound email, and inspect delivery outcomes from one service. Workspace-scoped API keys help keep access boundaries clear for applications and agent workflows. The public REST surface is designed to make transactional email easier to integrate while preserving visibility into what happened after a message was sent. SendHQ also supports delivery event visibility and inbound routing, so builders can connect outbound messages and replies in the same product workflow. Plans start at $9 per month, with options for transactional and marketing email as usage grows.
