I'd like to send an email out to a specific list of people based off of their Global ID's. The email will detail a percentage increase in pricing. The values vary depending on the recipients so I would like to tokenize the part of the message where the value will be included (e.g. "price increase for 2018 is 'x percentage'." How would I go about creating this token? Can I upload the CSV as-is and create the token?
