* Subject-verb agreement: "Mail" and "attached" are both plural nouns, but "refers" is a singular verb. You need a plural verb to match the plural subject.
* Meaning: It's unclear what you're trying to say. "Refers" usually implies something pointing to something else.
Here are some ways to correct the phrase, depending on your intended meaning:
1. If you're referring to multiple attachments:
* "The mail and the attached documents refer..." (This assumes you're talking about documents or files that are attached to an email)
* "The mail and the attached files refer..."
2. If you're referring to a single attachment that refers to something else:
* "The mail and the attached [document/file] refer..."
3. If you're referring to the mail and attachments as a whole:
* "The mail, including the attachments, refers..."
Example:
"The mail, including the attachments, refers to the meeting schedule."
Always double-check your grammar and make sure your meaning is clear!
