## Changelog

### 1.6 (2026-06-19) — Cleaner handling of empty input

- Submitting a run with no email addresses now returns a clear "no emails provided" message instead of silently verifying the demo addresses. The Console form still pre-fills sample addresses so the Try button works.

### 1.6 (2026-06-08) — Execution modes now apply their full settings

- Execution modes now apply the verification depth and insight settings they describe — e.g. Prospecting runs deep SMTP verification with batch and deliverability insights instead of falling back to the standard checks. Set Verification level explicitly to override the mode's choice.

### 1.5 (2026-06-08) — Much faster verification on large multi-domain lists

- Large prospecting lists (many companies, one contact each) now verify in parallel across domains instead of one domain at a time — a 900-email deep run that previously took over an hour finishes in a few minutes
- Default parallelism raised to 10 and the ceiling raised to 30 for big lists
- Domain authentication (SPF/DKIM/DMARC) checks now run concurrently per domain

### 1.4 (2026-05-30) — Faster large lists and SMTP simplification

- Large single-domain lists finish faster — billing no longer adds a per-email delay at the end
- SMTP verification now connects directly to mail servers, matching the rest of the toolkit

### 1.3 (2026-05-23) — Fix: rare hang when watchlist history store is unavailable

### 1.3 (2026-05-04) — Major upgrade — decision engine, deliverability simulation, watchlist mode, and richer outputs for cadence tools

### 0.1 (2026-03-25) — New features

### 0.1 (2026-03-25) — Major reliability and accuracy upgrade
