The emoji symbols seem like a good idea, but unfortunately just because its the first time you've communicated with a person for the day, doesn't mean that they _aren't_ incredibly busy. We may have different work cultures, but I used to report to someone who would lead with a bare "Hey!" and I eventually found that if I waited long enough she would either elaborate or the issue would go away. Somehow I don't think that was her actual plan.
