The 90-month gap between Privy ‑ Email, SMS & Pop Ups's and Klaviyo: Email Marketing & SMS's time-to-1,000 highlights how unevenly product-market fit landed across this birthday set — the leader found its merchant audience early, while late-rampers took multiple years to reach the same review depth.
