By popular demand, our Email a CSV Attachment step now supports dynamic values in the email subject and/or body. Simply reference the desired column using merge tags {}, and the email will automatically insert the first row from that column. All the details here!
But wait, there’s more! You can now use dynamic values in any field: email subject, body, recipients, and even the file name of the attachment.
Also: by default, the step will filter out any columns used as merge columns. You can un-select this option under Advanced Settings.
Enjoy!
