Hi, I've been battling with this issue for couple of months. I need to send bulk mail (not spam) through my social network to users in situations like newsletters, site invitations (when user imports their address book contacts)

I'm using shared hosting and it limits 500 mails per hour. Even though i manage to send mails most of them end up in user's spam box.

After researching these are the solutions that i finally came up with.

1) Use Google Apps SMTP (http://www.google.com/apps/intl/en/business/features.html) 2) Move into VPS 3) Use shared hosting with throttle enabled

Please advise me on what to choose.

Will using Google Apps prevent mail being sent as spam? I can't use other 3rd party SMTP like iContact or Aweber as "invitation sending script" will send emails to thousands of contacts, depending on user's addressbook.

Thanks in advance
