The use of third parties will be better, the mass function of their own difficulty is also large.

For example, Myemailmarketing is also based on PHP, but need to buy permission, mass when you need to use a computer to open it, mass during the need to keep the computer open.

My company used myemailmarketing to do mass, open myemailmarketing point mass has been waiting, may wait until the next morning, just after the 10W Mail, and sometimes network problems were stopped, need to reopen to continue to issue.
If you plan to use Phpmailer to make a mass system, you can imagine the efficiency is not higher than the myemailmarketing.

Later we use Sendy to do mass, it is said that mass efficiency is very high.

Overseas to do a bulk subscription to the general use of MailChimp, I see there are many mass services can be purchased.

Without a third party, PHP is very difficult to do, you can use Beanstalk or Redis to do Message Queuing, I used to use PHP to throw data in the queue, with the node. JS listening queue to send mail, properly.
