Amibguity in emails

A simple example to illustrate how amibguity can creep into emails:

The "incident" involves two persons:
P1: sends an email with voting options to determine how many people would like to take part in a cricket match at a particular date and time.
P2: one of the voters, reviews the status...

9.30 a.m.: P1 sends a mail saying:
"I have received only 7 votes so far, others please vote"
P2 responds to the mail by voting his option.

4.30 p.m.: P1 sends another mail saying:
"Since I have received only 3 votes, we will not have the match tomorrow"
P2 is confused and replies:
"How can 7 votes become 3 votes?"

What P1 really meant with his second mail was that he only received 3 votes for the match, hence the match will be cancelled.

P1 was not wrong, but he left room for ambiguity. Two possible ways of correcting it:
1. "Since we do not have enough votes, the match will not be held tomorrow"
OR (more specifically)
2: "Since I have only 3 votes for the match, which is less than the minimum 10 votes, we will not have the match tomorrow"
