What changed in 2026 that makes signal-driven outbound more important?
Three forces converged. Inbox providers tightened spam and secondary classifications so the baseline for primary-tab delivery moved up. Buyers trained themselves to delete generic openers because every tool ships the same AI-drafted template now. And more jurisdictions require consent and audit on cold outreach so the posture bar moved up. Signal-driven outreach that opens with a timely, specific reference clears all three bars at once.
