About

PostSignup automatically sends friendly, plain-text emails directly from your real Gmail or Microsoft 365 inbox based on triggers like new signups or user inactivity. Bypassing generic marketing templates, every message feels personal—exactly as if you wrote it yourself. You retain full control with strict send-only permissions (we never read your inbox), a complete audit log, and the ability to pause campaigns anytime.
