{% if Report.InvoiceBillToAddress.FirstName != '' and Report.InvoiceBillToAddress.LastName != '' -%}
{{ Report.InvoiceBillToAddress.FirstName }} {{Report.InvoiceBillToAddress.LastName}} <{{Report.InvoiceBillToAddress.EmailAddress}}>
{% else %}
{{Report.InvoiceBillToAddress.EmailAddress}}
{% endif %}
{% if Report.InvoiceBillToAddress.FirstName != '' and Report.InvoiceBillToAddress.LastName != '' -%}
{{ Report.InvoiceBillToAddress.FirstName }} {{Report.InvoiceBillToAddress.LastName}} <{{Report.InvoiceBillToAddress.EmailAddress}}>
{% else %}
