Ms Sue, can you please check these two sentences, I need to include in an email? Thank you.

1) Sorry, for disturbing you.
We have received email (emails) from four of your students, namely .....
2) Could you please let me have your list of students before tomorrow's meeting, so that I can talk to the parents of the participating students about our partnership?
3) I hope you had a nice weekend and I thank you for your cooperation again.

No vacation for me! Plane company was completely uncooperative! =(

1. no comma after "Sorry"
"email" (no -s on it) is a collective noun of sorts

3. OK

3. comma after "weekend"
