Data Mail「データ・メール」 is an online service for temporarily sending large files. According to the page, users can enter their own email address, the recipient’s email address, a subject, and a message, then send the download link for the uploaded files to the recipient. They can also choose not to send an email and simply display the URL, or send the URL to themselves. Its core positioning is not long-term cloud storage, but rather “temporarily sending files that are too large for email attachments via a download link.”
The service supports uploading multiple files by drag-and-drop or file selection, with a maximum of 10GB per transfer, and allows multiple files to be uploaded together. After upload, the system generates a download URL that users can copy; alternatively, they can send an email directly to the recipient through the page form. A download password is optional. If a password is set, the page states that it will automatically be sent as a second email. The retention period is clearly stated as 7 days, making it suitable for short-term delivery. The page also shows an option to “select from sending history,” suggesting that it may support choosing recipient information from past records, but we did not see more complete descriptions of team members, role permissions, shared workspaces, approvals, or audit features.
The captured text does not provide plans, pricing, free quotas, payment methods, or trial policies, so it is not possible to assess the business model or the upper limit of its value for money. From a security perspective, the ability to set a download password is a basic protective measure, but there is no visible information about transport encryption, file encryption, access logs, enterprise authentication, data residency, or compliance certifications. Information on third-party integrations, APIs, developer documentation, SSO, or enterprise integrations such as Slack/Teams/Google Workspace is also not present.
Its main advantage is a very straightforward workflow: upload files, set the email content, and generate or send a link, with a low learning curve. The 10GB maximum size and 7-day retention period are practical for temporarily sending videos, design drafts, compressed archives, client materials, and similar files. The downside is the lack of information about enterprise-grade capabilities, especially permissions, auditing, lifecycle management, and support channels. It is not suitable as a formal document management system or long-term file collaboration platform.
Access to this domain from mainland China cannot be determined from the page text alone, so it is marked as unknown. If cross-border transfers are unstable, businesses may consider domestic cloud drives, WeCom/DingTalk file sharing, Alibaba Cloud Drive Enterprise Edition, or international alternatives such as Dropbox Transfer, Google Drive, OneDrive, and Box.
