Dynamic or static segment?
- Dynamic — re-checked every time you use it, so it always holds whoever matches now. Good for "all new leads this week".
- Static — a fixed snapshot of who matched when you made it. Good for a one-time campaign.
Let bots do the tagging
A bot's Add / remove tags step can tag customers automatically — for example tag "Interested" when someone taps a button, or remove "New lead" once handled. The On attribute change trigger can start a follow-up when a custom field changes, say when a lead's status becomes "qualified".
Tag or custom field?
Use a tag for a group (*is a VIP*). Use a custom field for a value (*renewal date: 12 March*). Custom fields can also fill template variables, so each message carries that customer's own value.
