The Email / SMS Module allows for bulk sending of Email/SMS Templates to participants. 

Select a template from the dropdown and a list of all messages to send will be populated below. You can additionally check if the filter is correct and adapt this if necessary. 

Clicking on an item from the list will show a full preview of the message on the right side, note that individual e-mails cannot be edited. 

If a participant does not have a valid email address, it will be marked red with <no email address entered>.

At the bottom of the list you can see the number of messages which will be sent, and how many cannot. Clicking the Send button will start sending the messages, note that these are sent individually and so you need to keep the window open until sending is complete.
