Zoho CRM Email Notifications

Zoho CRM Email Notifications

Hello, 

I have created an email template in Zoho CRM which contain buttons to various dashboards and spreadsheets. I want to schedule this to be sent out every Friday however I can currently only do this by setting up a workflow to trigger the email based on criteria but in this instance I don't have a criteria. Just needs to be sent out weekly. 

Any suggestions on how to do this?
