Send password-protected files from your own email. The password arrives separately, by SMS, email, or date of birth. With SMS, the file and the key travel on two separate channels.
Drag and drop any file type - PDF, Word, Excel, images, and more. Up to 25MB per file.
Enter the recipient's email address and mobile number. The file goes to their email; the password goes to their phone.
The file arrives password-protected via AES-256 encryption. With SMS delivery, a separate text delivers the key: two channels, two layers of security. Email and date of birth delivery are also available.
With the MySecureSend Outlook Add-in, you can encrypt and send secure files without leaving your inbox.
Note: Each send supports one recipient at a time. The password is delivered privately to that recipient only.
An email arrives from your own Gmail or Outlook 365 address - not a third-party relay.
The attachment is password-protected (PDF, Office document, or ZIP archive depending on file type).
A separate SMS arrives with the password - completely independent of the email channel.
Note:Gmail may show a security warning on encrypted attachments - this is expected and confirms encryption is working. The recipient should click “Download anyway” to proceed.
Standard file types such as PDF, Word, and Excel documents are encrypted natively and open directly with the password.
Other file types arrive as AES-256 encrypted .zip attachments which require a compatible extraction tool to open.
Windows
7-Zip (free, 7-zip.org) or WinRAR
⚠ Windows built-in extraction does not support AES-256 encrypted zips
Mac
The Unarchiver (free) or Keka
Mobile
Files app on iOS supports encrypted zips natively. Android users may need ZArchiver or similar.
Once installed, right-click the zip file → Extract → enter the password from your SMS when prompted.
AES-256 - the same standard used by banks, governments and defence agencies worldwide. PDF files and modern Office documents (.docx, .xlsx, .pptx) are encrypted natively and open directly with the password. All other files, including older Office formats (.doc, .xls, .ppt) and any Office file that cannot be encrypted in its native format, are delivered as an AES-256 encrypted .zip instead: same password, same protection.
File contents never leave Australian infrastructure. Files and audit data are stored and processed exclusively in Sydney (AWS ap-southeast-2). SMS and password email delivery use overseas providers (Twilio and Resend), who receive recipient contact details and the delivery password only - never file content.
No. Files are encrypted with AES-256 on our Sydney servers, sent, and deleted immediately - they exist on our systems for seconds. MySecureSend has zero file retention: no file content is kept after sending.
Check the recipient's number includes the country code (e.g. +61 for Australia). If it still hasn't arrived after 5 minutes, contact support@mysecuresend.com.au.
MySecureSend is built to support your obligations under the Privacy Act 1988 (Cth) and the 13 Australian Privacy Principles. Subject line redaction keeps names, dates of birth and Medicare numbers out of email metadata (APP 11: security of personal information). Add zero file retention, Australian data residency for file contents and audit data, and a tamper-evident audit trail. Compliance itself rests with your organisation as the APP entity: MySecureSend gives you the controls to meet it.
One recipient per send: passwords are delivered privately to a single recipient per encrypted send. For multiple recipients, send separately to each person.
