Tags help you categorize and segment your audience in a way like Lists, but with the added benefit of having the same person in multiple places.The entire audience of a Tag can be enrolled in a Workflow, or used as a target for Bulk SMS. Your contact imports show up as a new tag with the date of upload.
Workflows (aka DRIP campaigns) are sets of automated tasks executed on a Contact (or lead) in a specific time sequence. You can manually or automatically enroll Contacts in a workflow.
Workflows have Sequences, independent jobs (such as SMS autoresponders, predictive dialers) that run after each other with configurable timestamps.
