An audience segment is a saved, named set of contact filters that you pick as a campaign audience. It updates itself: whoever matches the filters when you use it is in the segment, and nobody is added by hand.
An audience segment is a saved group of contacts that you send a campaign to. In Inrō, a segment is a named set of contact filters, not a list of people. Whoever matches the filters at the moment you use it is in the segment, so contacts move in and out on their own.
Filters, joined by one rule. Each segment uses either AND (match all filters, the default) or OR (match any filter).
A filter can look at what a contact did, such as going through a comment-to-DM automation, or at who they are. The contact filter entry in the Inrō glossary covers each type and the other places filters run. Filters can also be generated from a plain-language description of the people you want.
A segment can include a folder filter. With AND, "in the New Leads folder" plus "clicked a link in the last 30 days" gives you the new leads who showed interest in the past month.
On the Contacts page of the Inrō CRM. Apply at least one filter, press Create segment and give it a name. Each saved segment shows as a tab on the Contacts page, with a live count of the contacts who match right now.
You cannot add or remove a contact from a segment by hand. Membership comes only from the filters. If you want a list you control, one person at a time, use a CRM folder instead.
Use a segment when the rule matters more than the names: "everyone who replied to a story this week". Use a folder when the names matter: "the 20 people I met at the trade fair".
When you set up a DM campaign, choose your segment under Send campaign to. You can pick several segments and folders at once, and exclude others under Don't send campaign to. A contact who sits in two of them gets the message once.
The recipient list is fixed when you press send. People who match the segment later do not get that campaign, but they are in the segment the next time you use it.
