Workflow templates - Include displayname in subject
Many email providers group emails with the same subject which leads to time-consuming processes for many organisations, and many additional unnecessary clicks.
Some system workflow template subjects include the display name. Also it makes the email more personal as it is clear who it is addressed to. This is proven to be beneficial for open-rates of transactional mails.
