How to use {{=day}} and {{=bday}} attributes
The '{{=day}}' attribute can be used to mention the current day of the week in the email body or subject line.
Example:
An email containing “How are you this fine '{{=day}}'?” will transform to “How are you this fine Tuesday?” if the email was sent out on Tuesday.
The '{{=bday}}' transforms to the current business day.
Business days are currently defined as the weekdays (all the days of the week except for Saturdays and Sundays).


Example:
An email containing “Can we set a meeting on '{{=day+2}}?'” will transform to “Can we set a meeting on Wednesday?” if the email was sent on Monday.
However, when using '{{=bday+2}}', Saturday and Sunday will be skipped - meaning the '{{=bday+2}}' attribute will transform to “Monday” if the email was sent on a Thursday or Friday.
