THE OPEN SAMPLE DESK / 03 ORIGINAL FILES
Use fictional content to compare a mail client without exposing your archive. These are standard email files and a worksheet, not a Thunderbird iOS app or compatibility certification.
Subject: NP-01 — Tuesday’s café
Meet at 09:30. Bring: café notes, £5, and the blue folder. Second line: one & two < three.
Look for intact accents, punctuation and separate lines. The final angle bracket is ordinary text, not markup. A changed font is not automatically a failure.
Download plain-text message (.eml)Subject: NP-02 — A small agenda
This multipart message includes a plain-text alternative and a tiny HTML agenda: welcome, tea and a closing note. It contains no external image, font, tracking pixel or script.
Look for readable ordering in both viewing modes. The plain-text version deliberately carries the same information without depending on colour or layout.
Download text + HTML message (.eml)Subject: NP-03 — Three objects
The attached objects.csv lists pencil, notebook and cup with quantities 2, 1 and 1. It has a header plus three data rows, no formula and no personal data.
Look for the attachment name and save it. Open it as text to compare the contents; an icon alone does not show that all bytes arrived.
Download attachment message (.eml) · Get the expected CSVSave an EML file and open it with a compatible desktop mail application. The addresses use the reserved example.invalid domain. They are deliberately not deliverable. A successful preview shows local rendering; it says nothing about transport, account login or notifications. EML opening and importing differ between applications.
In your existing mail client, create a new message you control. Copy the first sample’s subject and body; for the attachment case, attach the expected CSV. Choose a real test inbox you own. Do not send to the fictional addresses embedded in the files. This site never sends mail.
Save the printable observation sheet. Record the client, version, device, date, sample and what you saw. It has separate columns for file display and real delivery so one result cannot silently stand in for the other.
For an optional non-sensitive receipt test, CleanTempMail provides a disposable receiving inbox. It is receive-only and anyone who knows its address may read it. Use these fictional samples, not private mail, recovery links or permanent account setup. Its web inbox is not an IMAP account for configuring a mail client.
These original files are free to reuse. No result here is presented as a test of unreleased Thunderbird iOS software.
Make a desktop backup plan with a separate recovery check, then trace missing messages, local archives or sent-folder problems using one identifiable sample.
