The gap

Everyone personalizes who to email. Almost nobody tests which message wins first.

Your customers A/B test subject lines after they send, when opens and replies are sunk cost. Nobody in outbound credibly answers:

"Which of these two emails will land better with VP Marketing at mid-market agencies?"

Lewsearch does, with a directional synthetic panel read.

Accuracy & appropriate use

Directional message screening

What Flash A/B is for

  • ✓Pick which variant feels clearer, more credible, less objectionable
  • ✓Pre-send concept screening before live A/B on real lists
  • ✓Fast iteration on subject lines, hooks, CTAs, and body copy

What the live send still measures

  • · Opens and replies stay with the live send
  • · Audited poll toplines stay with a panel study
  • · Inbox A/B stays on the real list after the directional read

Lewsearch synthetic panels are scored against published survey benchmarks. On the calibrated 50-state benchmark, the average miss is 7.07 points on the best 80% of 1,521 scored questions, and 10.02 points across all of them. A narrower April test on 5 places, 10,000 respondents, scored 7.47 points on 404 non-electoral questions. Flash A/B uses the same Lewis inference stack for open-ended message evaluation, appropriate for directional creative and copy decisions, not legal, clinical, or electoral claims.

Exclusivity

60 days. One category. First to sign wins.

What's exclusive

No other platform in your category (email sequences · AI SDR · LinkedIn outbound) gets a Lewsearch embed for 60 days from your launch date.

What's not

Direct Lewsearch sales, other categories, and white-label agency deals stay open. This is embed-partner exclusivity, not a blanket GTM lock.

After 60 days

The founding partner keeps the terms set on the call. The category can open for a second partner after 60 days.
