Shortwave vs Agentys: AI email client vs AI email assistant. Compare migration requirements, drafting capabilities, and workflow impact for 2026.

Shortwave replaces Gmail with a beautiful AI-native email client. Agentys adds AI to your existing client with zero migration. One requires you to switch; the other meets you where you are.

Replace your client vs enhance your client

Shortwave is a genuinely impressive product — beautifully designed, thoughtfully built, and one of the best full email client replacements available in 2026. If you want to rethink your entire email experience from scratch and are willing to invest the time to migrate, it is worth serious consideration. Agentys answers a different question entirely: not how do I get a better email client, but how do I spend less time on email altogether. It works on top of your existing setup, requires no migration, and drafts your replies overnight. For professionals whose main constraint is time rather than interface aesthetics, Agentys is the more impactful choice. For a broader comparison, see our best AI email assistants roundup.
