Sender Information Added to Guest Download One-Time URL Emails

Thank you for using Kozutumi.

We have updated the notification email that accompanies guest-download one-time URLs so that it now displays the sender’s information (Kozutumi display name & email address) as shown below.

Added item

• Sender: Display Name on Kozutumi <email address>

Unchanged items

• Expiration date

• Download link

• Reissue notice for the one-time URL

Final email format (sample)

Expiration date: 2025/05/26 15:16:57
https://app.kozutumi.com/guest/download_verify?xxxxxxxxxxxxxxx


You may access the download page from this URL only once.
From the second access, please reissue the URL for download.

Expected benefits

• Greater transparency – Recipients can quickly confirm who sent the file, reducing mistaken deletions and phishing concerns.

• Fewer internal inquiries – Because the sender is clearly shown, recipients no longer need to ask “Who sent this?” before downloading.

Kozutumi will continue to improve usability and security for all users. If you have any questions or feedback, please feel free to contact our Help Center.

Thank you for your continued support of Kozutumi.
