Create sending email template with 15 day delay

Create sending email template with 15 day delay

Hello,

I need to create a chain in which when a phase is updated in deal. For example, updating a deal to a proposal won in Zoho CRM, a Zoho CRM email template is sent after 15 days to that contact of the deal that It was updated. How would it be done? 

At the moment I have created what I attached. But I can't continue where it asks me for "Entity ID" - "To Email addresses" - and "User names"

I don't know that information because what I need is for this to work with any deal that is updated, not with one in particular.
