Sending an anonymous email attachment enables you to transmit a message in complete privacy, hiding the internet protocol (IP) address from which the message came. Oftentimes, these services function by transmitting messages across a random pathway through the network, obscuring their original sources. To send an anonymous email attachment, you will need to utilize a free online service.
Open your web browser and navigate to the page of your chosen secure email website; an Internet search should reveal several options for such sites if you do not have one in mind. Once you access the site, you will typically be presented with a screen that looks much like a standard email interface, containing option lines for the message recipient, the subject of the message, the body of the message, and a "Browse" button next to a box for attachments. Click on the "Browse" button next to the "Attachments" line. This will open a window providing you with a list of the active directories and files stored on your computer.
Once the window of directories opens, navigate to the specific drive and folder containing the attachment you wish to send. First, click on the letter of the drive containing the file you wish to attach, and then select the directory in which the file is stored. Once there, click the file you wish to attach and press the "OK" button on the interface. This will link the selected file to the email as an attachment. To complete the sending of your anonymous email attachment, simply enter a standard email address in the "To" box. List this as you normally would, such as "SampleEmail@example.net".
Following that, you will have the option to add a subject and body text to your message. If you are sending the anonymous email attachment to someone you know, it might be helpful to indicate this in the subject, to avoid the recipient's thinking the message is spam and deleting it without reading it. In many cases, if you leave the subject line blank or fill in something generic, the recipient might delete it without reading it, mistakenly believing it is junk mail. Additionally, adding a bit of text in the body of the message to give the email context might be important; something like "Hey, here's that attachment you wanted" will work under most circumstances.
