Why must the text go out in under 10 seconds?

Because the window is short: public speed-to-lead studies (2026 sources) show the odds of qualifying a caller collapse after 5 to 10 minutes — meanwhile, they've already dialed the next competitor in the directory. A text sent in under 10 seconds lands while they still have the phone in hand and the need is at its peak. That delay isn't a marketing detail: it's the difference between being the first answer and the fifth.
