The old way multiplies

Every new product shouldn’t mean another email stack.

Another account. Another API. More DNS, keys, webhooks, logs, bills, and places for replies to disappear. SendHQ turns all that sprawl into one reusable email layer.

A universal email primitive

Give anything an email.

A product, an app, an agent, or a person. Give it an identity that can send, receive, automate, and hand control to a human.

01 / Product

Products

Receipts, onboarding, alerts, confirmations, and every message your product needs to send.

02 / Service

Services

Background jobs, monitoring, billing, and internal systems with scoped sending identities.

03 / Agent

AI agents

Real inboxes, real identities, controlled permissions, full history, and a human within reach.

04 / Human

People

Inspect, reply, approve, pause, and take over without leaving the same shared workspace.

From receipt to reply

One API. Every email use case.

Stop treating every kind of email like a separate product. SendHQ carries the whole conversation while keeping identities, access, and reputation organized.

Transactional email

Every product message, through the same pipe.

Send receipts, password resets, onboarding, alerts, and notifications from identities scoped to each product and domain.

Integrate once

Your code learns one email API.

Every product and agent uses the same clean interface. Change the domain, identity, or workflow—not your infrastructure.

FAQ / 05

The useful questions.

The short version of how identities, domains, providers, and plans work.

Does SendHQ work with AI agents?

Yes. SendHQ is built for AI agents like Claude, Codex, Cursor, and OpenClaw. Its documented REST API uses a familiar Resend-style direct-send shape. Integrations should use a small server-side adapter and follow the migration guide for unsupported provider-specific fields.

Which mail provider does SendHQ use?

SendHQ runs on Amazon SES by default and is built on a pluggable provider layer, so providers can change through configuration instead of application rewrites.

Can I verify my own domains?

Yes. Each workspace can add and verify its own domains. SendHQ generates the SPF, DKIM, and DMARC records you need; you add them to DNS and SendHQ confirms verification.

Do I get a dashboard?

Yes. Every workspace includes a live inbox and outbox, domain management, API keys, and deliverability insights in the same interface.

How does pricing work?

Starter is $9/month for 10,000 emails and 15 domains; Scale is $29/month for unlimited emails and 200 domains. Marketing plans are $10 more per month with the same limits.
