Whats your time frame for deployment of the email?
You might want to stagnate it out... like loop through 100, pause for 10
secs, do the next 100, pause, repeat. Maybe longer if you could.
You could always have it record the number, stop it and adjust higher/lower
as required.
Also, make sure that you are able to tell what emails are kicked back and
logged as not being received (User not found, other kind of error in
sending).
Please let us know what happens, it would be excellent reference.

Subject: [PHP] Sending Broadcast Email - will a large loop cause a crash?
