For administrators with Remind Hub.

When you upgrade to the Remind Hub, it's important to make sure that all of Remind's domains are on your organization's list of approved email senders so that teachers, students, and parents receive messages. If your organization uses GSuite, Gmail, Microsoft Office 365 or Proofpoint, give these instructions to your IT Director so that they can check your organization's email servers, firewalls and content filters. 

This article contains the following sections:

• GSuite and Gmail
• Microsoft 365 
• Proofpoint
