A sending endpoint is not enough. Your app or agent gets a working mailbox, with an address, threads, and history, that it can operate through MCP, SDKs, or REST.

An identity

A real, verifiable email address your agent can use to sign up for services, receive confirmations, and act on your behalf.

Real conversations

Threaded replies, attachments, and multi-party threads, with a human in the loop whenever you want one.

Memory built in

Every message is a persistent, searchable record your agent can look back on to understand context and follow up.

Simple, per-mailbox pricing

JSON

React in real time

{
  "event": "message.received",
  "mailbox": "agent@yourdomain.com",
  "message": {
    "from": "customer@example.com",
    "subject": "Order #1042: where is my package?",

Subscribe to mailbox events with webhooks and trigger your logic the moment mail arrives, with no polling loops to babysit.

Node.js

Search and triage from code

const urgent = await mail.messages.search({
  query: 'is:unread label:urgent',
});

for (const message of urgent) {
  await mail.drafts.create({ replyTo: message.id });
}

Query the mailbox the way your workflow thinks: by sender, topic, or status. Then act on the results in the same call chain.

Shell

Script it from your terminal

$ hostinger-mail messages list --unread

$ hostinger-mail send \
    --to alex@example.com \
    --subject "Deploy finished"

The CLI speaks the same API, so anything your app can do you can also do from your shell, scripts, and CI jobs.

Hostinger Mail API FAQs

Answers about the Mail API, MCP server, SDKs, CLI, REST API, and webhooks.

Hostinger Mail API is the programmable email surface for apps, websites, and backend services. Send email and read, search, organize, reply to, and automate a real inbox through SDKs, CLI, REST API, and webhooks.

The live Hostinger Mail MCP server gives compatible AI agents mailbox tools they can call directly. Agents can use those tools to read conversations, search for messages, draft replies, triage incoming mail, and run inbox workflows.

Hostinger Mail API combines application email sending and real inbox control in one programmable surface. It is built for product and workflow email rather than high-volume bulk delivery.

First-party SDKs are available for Node.js, PHP, and Python. You can also use the command-line interface or call the REST API directly from any language that supports HTTP.

Yes. Webhooks let your application react to mailbox activity and start workflows without repeatedly checking for changes.

Sign in to hPanel, open the API area, and create a key for your integration. Keep the key secure and do not commit it to your source code.

Visit Hostinger Mail API documentation for setup guidance, API references, and integration details.

Yes. Use the REST API, SDKs, or CLI to send email and control a real inbox from any app, website, or backend. Agents through MCP are supported but optional.
