If you're going to be away from the office for an extended period of time - like attending a conference or going on vacation - then you can contact an Account Manager to pause your lead flow. Simply call 1-888-522-7355 ext 2 or email email@example.com between 8am-5:30pm CT, M-F.
For a low-hassle way to pause your leads for an afternoon or weekend you can also temporarily alter the settings within your online account. By adjusting the weekly volume limit below the number of leads you've already received this week, you're effectively pausing your lead flow until the new week begins on Monday. Just be sure to increase the weekly lead maximum setting once you return so you'll get your full volume of leads.
