Refined testmail.app

Read your testmail.app test emails in a real inbox, without a Pro plan. testmail.app gives you disposable inboxes for end-to-end tests. Its JSON API works on every plan, but Chrome shows the response as raw JSON. This extension turns that page into an inbox: a list of emails on the left, and the selected email on the right. Open your API URL as usual: https://api.testmail.app/api/json?apikey=YOUR_KEY&namespace=YOUR_NAMESPACE FIND THE EMAIL YOU NEED, FAST • Search across sender, recipient, subject, tag, and text. • Press C to copy the verification code or the first link. • Move with J and K, and press Ctrl+K or ⌘K for the command bar. • Mark emails as read, unread, or Done, with undo. DEBUG DELIVERY • See the SPF result on every row. • Open the metadata drawer for From, To, Message-ID, SPF, DKIM, and the sender IP. • Switch between the HTML body, the plain text, and the raw source. • Open the raw JSON with highlighting, collapsible sections, and a copy button. PRIVATE AND SAFE • Runs only on api.testmail.app/api/json pages. • Does not store your API key and sends no data anywhere. • Treats email content as untrusted. HTML renders sanitized, in a sandboxed frame that blocks scripts, forms, and remote images. Read, unread, and Done states live in the page only. A reload resets them.
