Email tags are used to categorize the email batches you send. It allows you to add remarks to different batches of emails. You can add an email tag when creating a new email task.
Log on to the DirectMail console.
In the left-side navigation pane, click Email Tags.
At the upper-right corner, click Create Email Tag. A dialog box is displayed.
Enter a tag name in the dialog, and click OK.
Note: You can create up to 500 email tags (loading tags is a timed behavior that usually takes about 5 minutes to take effect, we recommend that you create them in advance).
