Why it matters
From problem to solution
The problem
Personal emails flood B2B signups. Your sales team wastes time on tire-kickers while real accounts slip through with generic inboxes you can't prioritize.
How SignUp Guard helps
SignUp Guard analyzes domain patterns, provider reputation, and contextual signals to classify each email. Use the result to gate trials, prioritize onboarding, or trigger different signup flows.
