An AI agency we worked with cut their ad testing cycle from weeks to hours just by shifting message validation into SMS.
Normally, they would generate 50+ ad variants with AI and wait for Ads Manager to deliver statistical significance. But with SMS, they dropped those same messages directly into a local list and saw reply rates of 10-20% instantly.
This validated their messaging hypotheses faster and generated extra returns by feeding the proven copy back into their ads.
AI is great at scale, but one of the most important human moves is choosing the right channel.
