HTML is more than plain text
HTML email can contain formatting, links, images, and other markup. A web-based inbox should sanitize active elements and isolate message content so that an email cannot simply behave like arbitrary website code.
Links still matter
Removing scripts does not make every link trustworthy. A message can still direct a reader to a phishing site or a misleading download. Read the sender and destination before interacting.
Images can reveal information
Remote images may be loaded from third-party servers and can sometimes provide information about message opens or device requests. Consider blocking remote images when privacy matters.
Keep important conversations elsewhere
A temporary inbox is designed for short-lived communication. If a message is important, move the relevant non-sensitive information to a suitable long-term system rather than relying on the temporary mailbox.
Why HTML mail needs isolation
HTML email can contain formatting, links and other elements that make a message look like a full web page. Rendering that content directly in a site's main document can create avoidable security and privacy risks.
What a safer viewer does
A message viewer should remove active elements and isolate the remaining HTML from the surrounding application. Even then, users should treat links and remote content with caution. Technical sanitization reduces one class of risk; it does not determine whether the sender is trustworthy.
Why web inboxes sanitize HTML
HTML email can include scripts, forms and remote images. If a web inbox rendered that the same way a normal website is rendered, one message could affect the rest of the page. A safer viewer strips active content and isolates what remains.
Remote images and tracking
Some newsletters include tiny images that record opens. Blocking remote images is a privacy choice, not a guarantee. Even without images, links remain the main risk. Sanitization reduces one class of attack; it does not decide whether the sender is honest.
What users should still do
Read the sender. Check destinations. Do not enter passwords from a message. Keep important conversations in a permanent account. MailDroply’s message viewer is designed to display mail, not to certify that mail is safe.

Responsible use reminder
Use a temporary email address only for short-lived, low-risk tasks. Do not use MailDroply for banking, account recovery, medical records, government services, passwords or other information you cannot afford to lose. Keep the same address while you wait for a message. If the account matters, switch to a permanent mailbox you control.
Why isolation belongs next to the inbox
A message view is not a blog post. It should not run as part of the site chrome. That product choice protects both the reader and the publisher if advertising is later added around content pages rather than inside mail.
