This is odd, are the clients hitting refresh a bunch of times?

To correct this you could write out the person's email to a file and
check that before sending out an email to see if they've recently
received one.  Watch out for the multiple apache processes writting to
this file as there might be some concurrency issues.

How about putting this email request into a database and having a cron
job go through this database / file every minute or so and then emailing
out, carefully not sending multiple emails to the same person.
