Passing contact record to email alert

I am using the action to create an email alert. AWESOME feature! My email alert is using a Visualforce email template. I am passing the contact ID to the email alert but I am not seeing the email template receive it. Why?

I am receiving this in the email. "Recipient: "

is it because I am also using relatedToType?

Also, I tried removing relatedToType=“Account” and got the same result. And I tried hardcoding the ID I am passing to be absolutely sure nothing stupid is going on.

I ended up creating an Invocablemethod that sends an email to get around this.
