About

Elixpo Mails is the multi-tenant, event-based transactional email service for the Elixpo ecosystem. It helps a business send the everyday emails its product needs to send — receipts, welcome notes, order updates, password resets, invoices — beautifully designed, on-brand, and sent automatically when something happens in their app.

No mail server to run. No email HTML to hand-write. No shared "noreply@" address — the emails go out from your own mailbox, so they look like they came from you. Within the ecosystem, Elixpo Mails is the shared mailing infrastructure that backs the other Elixpo products.

This repository is the source for the mails.elixpo.com hosted service.

Who it's for

Any business or team that wants reliable, professional transactional email without standing up a whole email platform. If your app needs to email a customer when they sign up, pay, or place an order — this is for you.

Why it's different

• 📤 Your own sender. Connect your Gmail, Google Workspace, or any SMTP mailbox. Emails are sent as you, not from a shared pool — better trust and deliverability.
• 🎨 Design without code. A visual editor (like writing a document) with {{placeholders}} for the bits that change per customer — names, amounts, links.
• 🏷️ On-brand by default. Each product carries its own logo, address, phone, and footer, added to every email automatically.
• 📎 Attachments. Attach a file from Google Drive, a link, or a per-send variable (e.g. each customer's own invoice).
• 🔕 Unsubscribe handled for you. Built-in one-click unsubscribe and a suppression list, so you stay compliant without building anything.
• 📊 See every send. A delivery log shows exactly what went out, to whom, and whether it landed.

How it works — in four steps

1. Connect a sender — add the mailbox your emails should come from.
2. Create a product — this represents one of your services and holds its credentials and branding.
3. Design a template — write the email once, with {{variables}} for the personalized parts.
4. Add a webhook — your app calls a single secure URL when an event happens, and Elixpo Mails renders the template with that customer's details and sends it.

That's it — your product now sends polished, branded email on autopilot.

Built on

Elixpo Mails runs entirely on Cloudflare's edge network for speed and reliability — Pages + D1 + a cloudflare:sockets SMTP Worker (with send and retry queues) — and signs in through Elixpo Accounts (SSO). Senders are AES-GCM encrypted at rest, and webhooks are HMAC-signed. It's part of the Elixpo suite of products and provides the shared mailing infrastructure for the rest of the ecosystem.
