Most SaaS founders build their onboarding to impress, not to help. This founder figured that out the hard way. This is the email I wrote when he finally changed it. Signups to active users went up 40% in 60 days. No fluff, no feature tour, no checklist. Just a founder being honest with his list about what he got wrong and how he fixed it. That's the kind of email that makes subscribers trust you.
