html.cloud vs emailing an .html file
Email often blocks or flags .html attachments, the file then lives in inboxes and backups forever, and there's no expiry or update. html.cloud sends a private, encrypted link that opens as a page — and you can expire, replace, or delete it.
At a glance
| html.cloud | .html email attachment | |
|---|---|---|
| Delivery | A link that opens the page in the browser | A file the recipient must download and open |
| Deliverability | A normal link — nothing to strip | Often blocked, quarantined, or flagged as risky |
| Privacy | Encrypted in your browser; key only in the link | Sits readable in inboxes, sent folders & backups |
| Expiry & revocation | 7 / 30 days / never; delete anytime | None — once sent, it's out of your hands |
| Updating it | Replace behind the same link | Send a whole new email |
| Large files | Up to 10 MB via the link | Often bounce on attachment-size limits |
When to use which
Emailing the file is fine for something small, non-sensitive, and one-off, when you know the recipient's mail provider won't block it and you don't care that it lives in their inbox indefinitely. It needs no third-party service to view.
Use html.cloud when the file is sensitive, needs to look right when opened, or might change — a client report, a proposal, an AI-generated presentation. You send a link instead of an attachment, it's encrypted before it leaves your device, and you stay in control of expiry and updates.
FAQ
Why do HTML email attachments get blocked or flagged?
HTML files can contain scripts, so providers often treat .html attachments as a phishing risk — stripping, quarantining, or warning before download. A link avoids that, and an html.cloud link opens the page directly in the browser.
Is an email attachment private?
Not especially — it sits in the recipient's inbox and your sent folder, gets backed up, and can't be expired or revoked. html.cloud encrypts the file in your browser, keeps the key in the link, and lets you set an expiry or delete it.
Can I update a file after sending it?
A sent attachment is final. With html.cloud you can replace the file behind the same link, so the recipient always sees the latest version.
