Hi! 

I am planning to setup Zoho CRM for non-profit use. In this case, I would like to be able to link accounts together (for example, spouses, or mother and daughter). I would want to be able to address either both of them or one of them in a marketing email for example. Additionally, for when they are making donations, I would want to be able to pull up the donations for the 'household' and also 'single person' depending on what I am looking for. 

How would I go about doing this? 

In Salesforce and other CRMs you can show customer relationships with each other. How is this done in Zoho?
