How to send mass mail through vBulletin?
In order to send mass mail messages to your forum members navigate to your vBulletin admin control panel->Users->Send Email to Users.
Limit the number of the messages that can be sent at once. If your account is hosted on a shared server, either contact your hosting provider's support team and ask about the above limit or check for it in the corresponding Terms of Service section.
If the forum is set on a dedicated server solution most likely the above limit is not enabled. Still, in order to keep the load on your dedicated solution in reasonable bounds do not set this value very high.
Enter the corresponding information in the From, Subject and Message fields.
Then, based on different criteria you can filter the list of the recipients.
Click on the Send button located at the bottom of the page to send the mass mail.
