One of the best ways to make the most our Zapier integration is to automatically push your leads contact info into your CRM so all your clients are in one place (and here's a tutorial on setting up Zapier).
The list of CRMs integrated with Zapier keeps growing so check their CRM integration page to see if yours has been added. As of last check here some of the more popular CRMs that have Zapier integrations:
Follow Up Boss
Keller Williams Command
Sugar 6.2-5 & 7+
...and once you connect our app to your CRM it's just the start. So MUCH more is possible with Zapier!
