You might want to send your emails in smalled batches. You may overwhelm your server by doing so many at a time.

As for the MysQL server gone away error, that is a server issue. See this: http://www.vbulletin.com/docs/html/t...mysql_goneaway

i try to send 300 peoples but gtting same error...

how to check mysql think...

can u tell me step by step plzz.z..

If you get the same error when sending to 300, then go to less.

I am not a mysql expert. I really can't help you anymore than that page. You can either talk to your host about the error or, if it's your own server, you can change the settings in my.cnf to try to change the time limit or packet size. Or, you can hire a server person to fix these issues.
