LobsterMail vs Hostinger Agentic Mail

Hostinger Agentic Mail puts every agent on your own domain from day one, with deliverability handled for you, from 0,39 € per mailbox a month. LobsterMail is strong on autonomy and even scans incoming mail for prompt injection, but it gives you your own domain only on its paid Builder plan. Until you upgrade, your agents send from a shared LobsterMail address, not your brand.

Why choose Hostinger Agentic Mail?

Hostinger Agentic Mail gives developers and technical builders email that behaves like infrastructure, right inside the platform that already runs their business online.

Your own domain from the start

LobsterMail uses a shared address unless you move to its paid Builder plan. Hostinger puts every agent on your own domain from the very start.

One platform, low price

LobsterMail is a standalone service you run on its own. Hostinger bundles agent email with your hosting, domain, and email from 0,39 € a month.

Established and trusted

Hostinger is ISO 27001 certified and GDPR compliant, running email for millions of businesses. LobsterMail is a newer, standalone service without that track record.

Switching from LobsterMail
Moving from LobsterMail? Keep your own domain, create your mailboxes in hPanel or through the Hostinger API, then point your agent at the Hostinger REST API, webhooks, or MCP server. Your agents keep sending from your brand, with SPF, DKIM, and DMARC handled for you.

How Hostinger Agentic Mail works

Three steps to give an AI agent a working inbox on your own domain.

Create the mailbox

Add a mailbox on your own domain in hPanel or through the Hostinger API. Hostinger sets up SPF, DKIM, and DMARC for you, so you are ready to send right away.

Connect your agent

Point a webhook at your endpoint, or connect the MCP server to Claude, Cursor, and ChatGPT. Build with the TypeScript, PHP, or Python SDK.

Let it run

Your agent reads, sends, and manages mail through the REST API the moment a message lands, with allow and block lists keeping it in scope.

Simple, bundled pricing

Hostinger Agentic Mail comes with every Hostinger email mailbox on any plan, so your agents get real email without a separate service or a second bill.
