Attachments

  • Ask before you send.
    Make sure that the recipient is interested in receiving an e-mail attachment. The prevalence of viruses and other electronic threats makes this risky, and some recipients won't open any attachment unless they know it's safe.
  • Make sure the recipient can open the attachment.
    Most e-mail programs make it easy to attach a binary file (e.g., image, word processing document) to an e-mail message. However, such a file may not transfer successfully, and the recipient must have software that will open it.
  • Keep attachments small.
    The size limit for an e-mail message at NC State is 15 megabytes (MB). This includes the e-mail's text, any attachments, and the necessary encoding, which increases the message size by approximately one-third. For example, a 3 MB message would increase to 4 MB. If your attachment is more than a few MB, e.g., a video or a large group of photos, put the file on your Web site or send it by secure file transfer. E-mailing files is convenient, but it's also the most bandwidth-wasting and least reliable way to send them.
