SendHQ FAQ

How does SendHQ support transactional email workflows?

SendHQ provides a unified email workflow for verifying domains, sending transactional messages, receiving email, and inspecting delivery outcomes. Its public REST surface is built for product communication, so teams can integrate these steps programmatically. Clear observability and sender-safety controls are part of the design.

Does SendHQ compete with Mailgun as an email API tool?

Yes, Mailgun is listed as a direct competitor to SendHQ in the email API and developer tools space. SendHQ is positioned as a unified email workflow for product teams and AI agents, emphasizing domain verification, transactional delivery, inbound receive, and delivery inspection. Its public REST surface is designed specifically for serious product communication.

Which teams should look elsewhere because of SendHQ's limitations?

Teams that need a full marketing automation suite or a visual email designer should consider other tools, as SendHQ does not provide those capabilities. SendHQ is built as a developer-facing REST API for transactional email workflows rather than a platform for drag-and-drop campaign building or marketing automation.

Which teams are best suited to SendHQ?

Product teams and AI agents that need a coherent email workflow are the best fit for SendHQ. The tool combines domain verification, transactional send, receive, delivery inspection, and workspace-scoped API keys in one REST-based workflow. Teams that value observability and sender-safety controls in product communication will benefit most.

How is SendHQ priced?

SendHQ is a paid product and does not offer a permanently free tier. The pricing model is commercial rather than freemium, so teams should plan for a paid engagement from the start.

How does SendHQ help teams inspect email delivery outcomes?

SendHQ includes delivery outcome inspection as a core part of its unified email workflow. After transactional messages are sent, teams can use the public REST surface to observe delivery results. This observability is one of the sender-safety controls built into the product.

Can AI agents use SendHQ for email workflows?

Yes, SendHQ is designed for product teams and AI agents to share one coherent email workflow. AI agents can use the public REST surface to verify domains, send transactional messages, receive email, and inspect delivery outcomes. This makes the tool suitable for agent-driven product communication.

How does SendHQ manage API keys?

SendHQ provides workspace-scoped API keys, so access to its REST surface is managed at the workspace level rather than through a single global credential. This allows product teams and AI agents to operate within a defined access scope while using the same email workflow.
