It depends the project you work on. Typical scrum project is one that contains lots of smaller tasks - the standup is an opportunity for quick interactions, ad-hoc replanning (like don't do Y this morning, I'm not done with X. Should do Z today, not sure where to start, anyone can give me a hand ? Anybody remember what M is ?) Of course, you can and should do that anytime you are in need, but the standup meeting is a small time allocated where you have the attention of to the whole team. It can be done in an email - but generally people are not as succinct or too succinct and dialog does not really happen. If dialog does happen in your team, and you spend less time writing email than joining the meeting then why would you not do it via email ?
