+On 2026-10-22, the owner reported that password entry and the one-message authenticated SMTP transport test worked. The specific received-image rendering result was not captured. Preapproval and postapproval campaign tests pass through local pickup, and dispatch controls pass disposable-MDB pickup tests. Owner inbox review, live pilot, backup, and restore gates remain open.
 
 1. All P1 stories and T01-T32 applicable to the chosen provider pass.
 2. Sender domain and provider limits verified; the system can display provider rejection and halt safely.

+- Offers an explicit, single-message SMTP transport test to the configured `SMTP_TEST_TO` address.
 - Reviews a campaign against unsuppressed contacts, adds an advertisement, postal, and reply opt-out footer, tests the reviewed message only to the internal inbox, and records approval in a paused state.
+- Uses tabs for Overview, SMTP, Contacts, Templates, Campaigns, Sending, and Reports. Contacts includes import and global suppression.
+- Sends approved campaigns only while the HTA is open, with a configurable account-wide gap between attempts. It pauses on restart and uncertain outcomes, rechecks suppression before each send, and requires a fresh mailbox opt-out review before resuming.
+- Sends a test of an approved campaign to the internal inbox without advancing delivery counts, and exports delivery and attempt CSV reports to `REPORT_DIR`.

 5. Enter opt-out replies in the suppression form. Press **Set or rotate SMTP password** to enter the password locally, then press **Send one internal test**. The owner reports that this authenticated SMTP test worked on this PC; detailed received-image rendering has not been separately recorded.
 6. Put template files under `TEMPLATE_ROOT` and import them from the HTA. The accepted HTML subset and example are in [templates/README.md](templates/README.md). Imported versions are immutable snapshots. The template preview shows stored content, while the campaign preview adds the full footer.
 7. Fill in `BUSINESS_POSTAL_ADDRESS` in local `config.ini`. Enter a campaign name and subject, select an imported template, and press **Review message and recipients**. After checking the full preview, send the campaign-specific test to `SMTP_TEST_TO` and confirm it arrived. Approval records paused deliveries; it does not start sending.
+8. In **Sending**, send an optional test of the approved snapshot to `SMTP_TEST_TO`. Check the monitored reply mailbox, record opt-outs under **Contacts**, then mark the mailbox reviewed and explicitly resume the selected campaign. Keep the HTA open while sending. Use **Pause all** to stop new attempts and **Reports** to export delivery and attempt histories.
 
 Local `config.ini`, MDB files, logs, backups, and temporary test data are ignored by Git.
