How to drop off and pick up files in SendTo

Last modified 3/22/2024

SendTo is a web-based application that allows you to share files with others securely.

SendTo allows students, faculty, and staff of Illinois State University to share files with others in a secure manner. You can use SendTo to share files with other members of the University or with third parties.

Use SendTo to share files when:

  • Files are too big to be sent as email attachments
  • Files contain Restricted or Highly Restricted data
  • You want to share files with someone
  • You want to share sensitive information (FERPA)

When you use SendTo, you will upload files to the SendTo website and add one or more recipients. After you drop off/send the files, an email is sent to all recipients with a link that allows them to download the files. When your recipients download files you've dropped off, you will receive an email notification so you know the files have been downloaded.

Dropping Off Files

To share files with others using SendTo, do the following:

  1. Go to and log in with your ULID and password.
  2. Once logged in you will see a page with standard message formatting. The fields you will see are (Figure 1):
    1. To: Here is where you will add the recipients for the message. Note: For multiple recipients, add a comma between each email added. 
    2. Subject: Here is where you will add the subject for the message. 
    3. Message: Compose your message to be sent here. 
    4. Attached Files: Drag and drop or click the green +Add Files button to add any necessary attachments for the message. 
  3. Once you have your message ready, you can chose to let it expire after a certain number of downloads, send a copy to yourself, or keep it private. Once ready to send, click the red Send button at the bottom (Figure 1).

You will receive an email notification from SendTo when your recipient(s) download the file(s) you have sent. A copy of the SendTo message can also be sent to you. The email message will have the Subject of "File Download Receipt [ID: 12ABC345DEF6789GHI] subject Message (The ID will be random and the subject message will be whatever you entered into the Subject field).


  • Please note when using SendTo, users should send emails to only individual email accounts. Sending emails to Listservs, shared email accounts, or aliases will result in the receiving party not being able to access the files.
