Hi everyone!

Let's say I have a PHP website with 100 users. I store user information in my database, such a their username, password, and email address. Now if I wanted to send out periodic emails, auto-response emails, etc, what would be the best thing to use?

I was thinking about using the phpmailer class and sending them using my mail.mydomain.com server. However, how can I make sure that I'm not sending too many emails at once to clog the server? Is there a limit on simultaneous emails?

Also what if my user list grows to 10,000? 100,000? or more? What would be the best thing to use for websites with a very high email volume? Thanks a lot for the help, I find this whole email thing a little confusing so any input is greatly appreciated![/url]

Good idea, however your shared server is limited to 200 emails per hour. HostMySite offers a free list server with it's plans just in case you need to send out mass emails.

So I say talk to support about activating your list server, by default you get 5,000 emails per month but that amount can be upgraded.

If you plan on sending more than 50,000 emails a month then you need to look into a VPS solution. You should be prepared to learn A LOT about how email works because it takes some time for your IP to get whitelisted with AOL, Yahoo!, MSN etc. and you should be prepared to jump through some hoops.
