Send email before the end date on the table

[İclal Aslan]

I have a table which shows the end and start dates of the certifications.

I want to send an email 2 days before the end date. I used this smart value condition but it does not work. And even I do it this way I do not know how it would work for multiple end dated certifications.

{{ page.body.match("\\d{1,2} \\w{3} \\d{4}").last.toDate.minusDays(2).format("yyyy-MM-dd") }}

equals

{{today().format("yyyy-MM-dd") }}
