Tags can easily be added to contacts so you can send a one time message to them.  This is great for product updates or custom communication based on certain attributes.

A contact may have multiple tags separated by a ",".

To add a tag, re-upload your contact data by adding another column that contains the data.  The column should be mapped to our Tag field.

Or, manually update by clicking on contacts, edit and update the tag.

Once you have added Tags, you can easily send a one-time message to the tagged contacts.
