Yes, you can disable FunnelFox at anytime. To do so,
Go to: Left sidebar menu > Salesforce > turn the “sync email” switch off > click save
We recommend you don’t do this straightaway. As we sync once every 15 minutes, you would only be able to see FunnelFox’s benefit after some time if you haven’t received a few emails immediately after signup. Our system will send you an email as soon as your first email has been synced.
