Email Testing

Hooklistener provides inbound email testing through hookinbox.com. Create test inboxes that capture emails and let you inspect their content without setting up a mail server.

How it works​

  1. Create an inbox — get a unique email address at @hookinbox.com
  2. Send emails to it — from your app, transactional email service, or mail client
  3. Inspect captured emails — view subject, body, headers, and attachments in the dashboard

Key features​

Inbound email capture​

Every email sent to your inbox address is captured and stored. No mail server setup required.

Full email inspection​

View complete email details:

  • From / To / CC / BCC — all recipient fields
  • Subject — email subject line
  • Body — HTML and plain text versions
  • Headers — all email headers (SPF, DKIM, etc.)
  • Attachments — attached files

Real-time updates​

New emails appear in the dashboard instantly, similar to the webhook inspector.

Use cases​

  • Test transactional emails — verify email content from your application
  • Email parsing development — develop and test email parsers
  • QA and staging — capture emails in non-production environments
