The most common reason for emails aren't sending various solutions is the reset of the mail profile associated with your Proclaim user profile. To resolve this, follow the steps below.
Note: To do this, you need to have access to User Profiles on your Proclaim Toolbar.

Select the correct user profile.
Click the Email and Printing tab.

Tip: This is usually located in the top-left, above the password field.
Ensure the Default box is ticked.
Input the email address then click Save.
