Create an Inbox

Set up a test email inbox to capture inbound emails.

From the dashboard​

  1. Navigate to the Email section in the sidebar
  2. Click New Inbox
  3. Enter a name for your inbox (e.g., "Signup Emails")
  4. Hooklistener generates a unique email address:
[email protected]

Sending test emails​

Send emails to your inbox address from any source:

  • Your application's email-sending code
  • A transactional email service (SendGrid, Postmark, SES, etc.)
  • Your personal email client (for quick testing)
# Example using curl with a local SMTP relay
echo "Test email body" | mail -s "Test Subject" [email protected]

Viewing captured emails​

Emails appear in the dashboard in real time. Click an email to view:

  • Envelope data — from, to, subject, date
  • HTML body — rendered HTML content
  • Plain text body — text/plain version
  • Raw headers — complete email headers
  • Attachments — any attached files

Managing inboxes​

  • View inbox — see all captured emails for an inbox
  • Delete emails — remove individual emails
  • Delete inbox — remove the inbox and all its emails

Email address format​

Inbox addresses follow the pattern:

<slug>@hookinbox.com

The slug is auto-generated based on your inbox name but can be customized. Emails sent to any address matching your inbox are captured.

Limits​

The number of inboxes and email retention depend on your plan. See Plans & Billing for details.
