Attachment blocking is a deliberate security feature that reduces malware risk and keeps temporary mail fast and anonymous.

Security First by Design

Temporary inboxes are built mainly for receiving codes and confirmation links. By limiting messages to text and HTML, providers remove a major attack surface and reduce the chance of users downloading harmful files.

Why Attachment Blocking Matters

Many phishing and malware campaigns rely on infected documents, PDFs, or executables. Temp mail is often used with low-trust websites, so the risk is higher. Disabling attachments directly cuts this threat path.

Performance and Anonymity Benefits

Allowing attachments requires heavier storage, scanning pipelines, and more infrastructure. Keeping inboxes lightweight helps services stay fast, disposable, and privacy-focused for short lifecycle usage.

Conclusion

Attachment limits are not a missing feature but a core protection layer. You still get the message content you need while avoiding high-risk file execution vectors on your device.
