Word to describe an email missing an attachment

Question

Have you ever sent an email, intending to attach something and referring to it in the email, but without actually attaching? I'm wondering if there is a word or words to describe:

1. The email itself. e.g. 'I just sent a ????? email'

2. The act of sending such an email. e.g. 'I just ?????ed'

Any proposed word(s) could/should encapsulate concepts of incompleteness or emptiness and/or fact that email was sent prematurely.

I'm not thinking about emails that should have multiple attachments but are incomplete. It's really those simple, '1 attachment' emails.

UPDATE: Playing on another meaning of 'attached', I thought that an email without an attachment could be considered to be 'unattached'. Some words which came up when looking for synonyms were 'single', 'unwed' and 'bachelor'. I don't think any of these are quite right, but hopefully they may inspire others....

Answer 1

"Attachmentless."

Or, you could simply say "E-mail without the intended attachment." There's not exactly a thing for which we've needed an English word.

Answer 2

I might use a compound adjective for the 'I just sent a ????? email' situation:

'I just sent you an empty-shell email'

And for the 'I just ?????ed' situation, I might say this:

'I just ghost-emailed you'

...but I'm not aware of a standard form for announcing such mistakes. The most common form of acknowledgment used in intra-office email messages at my workplace is simply a follow-up email message with the attached document included as intended, and with a single line of message text along the lines of:

This time with the attachment.

Answer 3

Here's a thought. Playing on the ( to me at least ) recent appearance of the phrase ' my bad ' which I take to mean the acceptance of responsibility for an error, I propose ' my b@d '. This could be taken to describe an error in composing or sending an email. In a similar vein, to describe the problem email itself I propose ' efail ' or ' ef@il'.
