What CSV columns are required?
A phone number is required on every row; it is validated and standardized to a common format, and rows without a usable number are rejected. Name fields and tags import when present, with header names normalized so common variations map cleanly. Test your vendor's actual export with a small synthetic file before the production import.
Can I sync leads from my CRM automatically?
Not natively. Lists are imported by CSV, which keeps the file in your hands and the verification in your process. In the other direction, a signed webhook can push call dispositions to your CRM so outcomes land where your operators work. An admin on a Jetstream seat sets up and reads the export; delivery covers the workspace's dispositions, including Breeze callers, whenever the workspace has at least one Jetstream seat. That is event handoff, not list sync, and your CRM remains the system of record for contacts.
How do I dial only part of a list?
Session setup filters by list, lead status and lead list, or by up to 200 explicitly chosen leads, so the queue matches the campaign you planned. Groups in the sidebar carry live counts so you can see each slice before you open it. The dialer applies quiet hours, DNC and attempt caps on top of your selection.
Can I get my leads back out?
Yes. An admin can export the lead table as CSV, which covers audits, migrations and moving to another tool. The export includes the lead fields, not the call audio, and it is an admin action by design so bulk data movement is deliberate. For outcomes flowing to another system, use the signed disposition webhook. An admin on a Jetstream seat sets up and reads the export; delivery covers the workspace's dispositions, including Breeze callers, whenever the workspace has at least one Jetstream seat.
Does importing a list make it legal to dial?
No. Import is a data step. Eligibility, registry review, permission evidence and calling windows are your business's responsibility and happen before a list is released to a session. The dialer enforces the internal policy you configure, including DNC, quiet hours and caps, but those controls support your policy; they do not create permission to call anyone.
