If you want to prevent Syncro from sending emails to a specific (Customer) Organization (including all Contacts/End Users associated with that Organization), you can. 

Note: Customers are in the process of being renamed to (Customer) Organizations, and Contacts to End Users. You may see both in Syncro for the time being.

Disable Emails

Follow these steps:

1. Navigate to the (Customer) Organizations tab/module.
2. Click the (Customer) Organization's name to open its Details Page.
3. In the upper right, click Edit.
4. In the SETTINGS section, check the “No Email - Of Any Kind (Including Contacts/End Users)” box.
5. Click Save Changes.

Troubleshooting

Syncro doesn't warn you when you try emailing a (Customer) Organization (e.g., via a Ticket Communication) with this setting enabled. Your (Customer) Organization will simply not receive the email.

If you discover that the “No Email - Of Any Kind” box is becoming checked automatically, it’s usually for one of the following reasons:

1. Our email partner, SendGrid, wasn’t able to successfully deliver the email to the intended recipient. When an email bounces like this, the “No Email” box is checked automatically to prevent future bounces. 
   To start sending email to this (Customer) Organization again, change the email on file in Syncro to a valid email address, uncheck the “No Email” box, and save your changes. 
   If you continue to experience issues, consider the Syncro Email Options for Maximizing Deliverability (specifically, SMTP) or contact Support for further assistance.
    
2. A (Customer) Organization has mistakenly disabled all communications from within the privacy settings of their End User Portal. 
   To start sending emails to this (Customer) Organization again, uncheck the “No Email” box and save your changes.
