Frequently Asked Questions

Why are people looking for Shortwave alternatives?

The main reasons are Gmail-only limitation (no Outlook support), wanting more than AI-assisted email processing (some people want email handled for them entirely), lack of calendar and task management, limited team collaboration features, and the feeling that AI summaries and search are incremental improvements rather than a fundamental change in how email works.

What's the biggest difference between Shortwave and alfred_?

Shortwave helps you process email smarter with AI features like search, summaries, and writing assistance, but you still do the processing. alfred_ processes email for you autonomously: it triages your inbox, drafts replies in your voice, extracts tasks, and manages your calendar. You review and approve instead of reading and deciding. It's the difference between a smarter tool and a digital assistant.

Which Shortwave alternative works with Outlook?

alfred_, SaneBox, Spark Mail, Missive, and Mailspring all work with Outlook. Shortwave and Superhuman are both Gmail-only, which is a dealbreaker for many professionals whose companies use Microsoft 365. SaneBox works with any email provider since it operates at the server level.

Is there a free alternative to Shortwave?

Yes. Spark Mail offers a generous free tier with AI writing assistance and smart inbox categorization. Missive has a free plan for team email. Mailspring is open-source and free for basic features. Even Shortwave itself has a free tier, but if you want more or different features without paying, Spark Mail is the strongest free option.

Which Shortwave alternative is best for teams?

Missive is the best option for teams that need shared inboxes, email assignments, and real-time collaboration on drafts. Spark Mail is a close second with shared drafts and delegation at a lower price. Shortwave and Superhuman are both focused on individual productivity and lack meaningful team features.

Can I try these Shortwave alternatives for free?

Yes. Spark Mail, Missive, and Mailspring all have free tiers you can use indefinitely. alfred_ offers a 30-day free trial. SaneBox has a 14-day free trial. Superhuman and Hey do not have free tiers. Most of these tools let you test them before committing to a paid plan.
