Tags find people. Groups choose them.

Tags and groups get used as if they were the same list. They are not. A group is who a campaign sends to. A tag is a label that stays on the contact so you can find them later in Contacts or Messages.

You can add tags in bulk from the Contacts list, from a right-click or bulk select in Messages, or from Add tags while you set up a Text Blaster or round-robin campaign. Search an existing tag or type a new name. Adding never replaces tags already on the person. They stack.

Because the tag lives on the contact, it shows on every conversation with them: as a chip on the inbox row and next to the name in the open chat. That is useful when you label a hot lead while the thread is still open, and less useful if every person invents a new spelling. A short pattern, such as a campaign name plus a month, or a stage name, keeps the filter usable.

Campaign tags are narrower than they look. They are added only to contacts whose message was accepted for sending. Skipped people, including DNC and opted-out numbers, do not get the tag. Filter by that tag later and you are looking at people who were actually queued, not the whole group you started with.

The filter is in Contacts under Filters, and Messages can filter by tag the same way. That is the follow-up path: see who received a promotion, then decide whether they belong in a group for the next send. The tag itself will not be the audience.

A long list of tags that were each used once is harder to filter than a short list the team agrees on. Groups still have the 5,000-person cap and the blast picker. Tags do not.

The click-by-click version lives in the Contact Tags guide.
