Emails templates are a really convenient way to create reusable emails, automatically filled in with guest, reservation, agency and owner information.
Edit or create a new template.
Fill it with variables (a tag that will be replaced by the actual value) sorted in a drop-down.
As you can see in the preview, the variable [<RES_GUEST_FIRSTNAME>] becomes “Roger”.
Select properties on which a template is available (all by default).
Or show it only in inquiries, hold dates, etc (all by default).
