Try it out for yourself

We use PieSync to synchronize our Google G Suite account with our CRM and Marketing Automation platform. PieSync was crucial to whether or not we went ahead with our projects. Without PieSync we would have abandoned the projects and all the benefits we’ve gained from it. It was a real situation of “to sync or not to sync".

Our staff loves how easy it is to tag prospects and customers based on their industry and product interest in Insightly. PieSync’s intelligent syncing helps translate all of these tags effortlessly into various segmented e-mail campaigns in Mailchimp.
