Use case

Temporary email for testing transactional email

A template preview is not the same as a delivered message. Test through the real sending path and look at what lands.

What delivery testing catches

  • Broken links and wrong environment URLs.
  • Missing or malformed headers and sender names.
  • Messages that never leave your provider's queue.
  • HTML that renders badly or has no plain-text part.

A quick routine

  1. Create an address.
  2. Trigger the email from your app.
  3. Open it and check subject, sender, links and content.
  4. Repeat for each template.

Frequently asked questions

Does Emailsify show the HTML version?

The website renders messages in a sandbox so scripts cannot run. The MCP tools return cleaned text.

Can I test attachments?

Message text and HTML are stored. Do not rely on attachments for testing.
