If you're just starting out with Lead Liaison or your IP address has changed you will need to warm up your IP address to develop a reputation with the ISPs. If you suddenly send out 30,000 emails in one day from a new IP your messages will be limited or purposely throttled by ISPs. If you're in the thousands of emails to begin with you might avoid scrutiny. However, if bounces, spam complaints, or spam trap hits represent a high percentage of your emails sent you'll damage your reputation right out of the box. Make sure you initial sends are to very clean lists.
