Setting Up Email Mailboxes

A mailbox in Blocx is an inbound email address managed by Blocx — every new mailbox is allocated a unique random local part on the platform's inbound domain (something like q7k4p2j9x3m1b8t6@…). You can read messages in the dashboard, download the raw RFC-822 source, and stream new messages to your application by webhook.

Manage mailboxes at Email → Mailboxes.

When to use mailboxes

Mailboxes are the right fit when you need an addressable inbound endpoint — for example, parsing replies, capturing support tickets, ingesting bounces from your own listserv, or routing structured data emailed to a workflow. If you're forwarding mail from your own domain, set up a forwarding rule on your mail provider that points at the Blocx-issued address.

Creating a mailbox

  1. Open Email → Mailboxes.
  2. Click New mailbox.
  3. Give it an optional label so you can recognize it in the list (e.g., "Support replies", "Webhook ingest").
  4. Click Create.

The mailbox's full inbound address is shown on the detail page — copy it to your provider or whoever needs to send to it.

To process inbound mail in real time, configure a webhook endpoint at Developer → Webhooks and subscribe to the email.received event.

Viewing messages

Click a mailbox to see the message list at /email/mailboxes/<id>/messages, newest first. Click any message to see the parsed headers and body. You can also download the original RFC-822 .eml source from the message detail page — useful when you need the raw bytes for forensics or to replay it through another system.

Renaming or deleting

Use the actions menu on a mailbox row to update the label or delete the mailbox. Deleting stops accepting mail at that address; messages already received remain accessible until the mailbox is deleted.
