It would be incredibly helpful to use merge tags as dynamic date inputs for countdown timers in automated emails. For example, if we notify a user that their miles or something are expiring in 7 days we’d love to insert a merge tag like {{miles_expiration_date}} as the target date. This way, each recipient sees a personalised timer based on their actual expiration date with no manual updates needed. It would unlock powerful use cases for loyalty programs, promotions, and more.
