Blast Radius
A registry of WhatsApp blasts — batch campaign sends, as opposed to the per-customer comms blueprints fire. Records what went out (including blasts sent outside Atlas); open a blast for live WhatsApp performance (recipients, read %, fail %). There is no edit — delete and re-record to correct an entry. One row per template per day (London); a second same-day send of the same template is rejected.
Size an audience
A live count of the WhatsApp households a blast would reach — engaged customers (≥1 completed switch) reachable on WhatsApp, staff excluded — plus a CSV of the recipient list (identifiers only, no contact details).
Set filters and preview to size the audience.
Sent, not yet recorded
WhatsApp sends from the last 90 days that look like blasts (a big one-day push) but aren't in the registry.
