Shortwave alternative
Best Shortwave Alternative in 2026 (Approve Before It Sends)
Shortwave is a polished AI email client rebuilt for Gmail - great natural-language search, thread summaries, bundles, and an AI assistant. AutoEmail takes a different stance: it drafts every reply for you and holds each one for approval, across multiple businesses, and beyond Gmail alone.
Why people look for a Shortwave alternative
Shortwave is one of the best AI email clients out there. Its natural-language search, AI thread summaries, smart bundles, and assistant are genuinely strong, and its 2026 Tasklet feature adds an AI agent layer that can automate multi-step email workflows. If you live in Gmail and want a beautiful AI-native client, Shortwave is an excellent pick.
The first reason people look elsewhere is platform: Shortwave is Gmail-only. Outlook and Microsoft 365 are not supported, so anyone on Microsoft mail, or running a mix, is out of scope.
The second is the send model. Shortwave's newer Tasklet automations can run multi-step workflows with little or no human intervention. That is powerful, but for customer-facing email some operators want the opposite default: AI drafts everything, but a human approves every send. They also want clean separation when they run more than one business from one place.
Why AutoEmail is the better fit
AutoEmail is built approve-first. It drafts a reply to every incoming email in the right voice for the right business, scores it for spam and risk, and holds it for your one-tap approval. Nothing reaches a customer without you - the default is review, not automation.
It is not tied to a single mail provider the way a Gmail-only client is, and each business inbox is fully separated: its own context, signature, contacts, and analytics in one workspace. Run several brands without crossing wires.
And the same inbox is agent-driven through a documented public API. An AI agent can read, draft, and stage sends while human approval still gates the actual send. If you specifically want Gmail-native search and bundles, Shortwave is the stronger client; if you want approve-first AI drafting across providers and businesses plus an agent API, AutoEmail is the better fit.
