Quick question about onboarding

From

Jamie Lee · Founder, Lumen

Hi team, Loved the initial sequence. One tweak: could your AI replies keep things casual when we reach out to founders from the event list? Don't want to sound too stiff. Thanks!

AI Reply Draft

Brand tone matched

Hey Jamie! Absolutely—I'll keep responses relaxed, first-name based, and add quick context about the event touchpoint so it feels natural. If a thread gets technical, I’ll still match the vibe. I’ll push the updated tone guardrail live now.
