Hey Product Hunt! 👋 I'm Sabeur, and I built Lastline because I lived this chaos personally. You spend time designing a beautiful company signature. You send it to the team. Half of them ignore it. Within a month you're looking at 15 different signature styles floating across customer emails — some with old logos, some with wrong phone numbers, one with Comic Sans (yes, really). Email signature management is a deceptively painful problem. And no tool was solving it for Google Workspace teams the right way. One question for the PH community: what would make you switch from your current signature setup tomorrow? We're actively building based on feedback and would love to hear what's blocking you. 🙏
