I use Notion Mail, and I liked the parts that made email feel calmer: labels as real views, simple rules, and an inbox that stayed close to Gmail instead of becoming a whole new system. When Notion said that inbox is going away on September 22, 2026, I started building Mejl for myself.
Mejl keeps your mail in Gmail, then adds label-based inboxes and simple rules that stay in sync. The goal is not a pixel-for-pixel clone. It is to preserve quick navigation, understandable rules, and an inbox quiet enough to use every day.
