💡 Our Take
Choose Superhuman Mail if you need a polished premium email client for Gmail or Outlook with strong keyboard-driven productivity, AI replies, scheduling, and business workflow integrations. Choose Shortwave if your priority is a modern AI-first Gmail experience and you want to compare a more inbox-reinvention-oriented product before committing to Superhuman’s Business pricing.
Superhuman Mail - Pros & Cons
Pros
- ✓Superhuman says Mail saves users 4 hours every week, which makes the product most compelling for people who process large inboxes daily.
- ✓AI features are embedded directly into email workflows, including Auto Labels, Auto Archive, Instant Reply, Auto Summarize, and follow-up reminders, rather than existing only as a separate chat assistant.
- ✓Instant Reply and voice-and-tone matching are designed for fast outbound communication, and the Superhuman website says users consistently write emails twice as fast with Instant Reply.
- ✓Ask AI can retrieve information across the inbox, calendar, and the web, reducing the need to remember senders, keywords, or subject lines.
- ✓Business users get useful workflow integrations inside the inbox, including HubSpot, Salesforce, Pipedrive, Jira, GitHub, Figma, Zoom, Google Meet, and Microsoft Teams connections mentioned across the pricing and product pages.
- ✓According to Superhuman’s AI privacy and security statements, AI is opt-in, users can opt out at any time, LLM providers have Zero Day Data Retention, email data is not logged to AI subprocessors, and customer data is not used for model training.
Cons
- ✗Mail is positioned as a premium product: the plan that includes Superhuman Mail is listed at $33 per member per month when billed annually or $40 when billed monthly, which is much higher than standard Gmail or Outlook access.
- ✗The website frames Superhuman Mail around Gmail or Outlook users, so teams using other email infrastructure may not get the intended experience.
- ✗Some advanced security and administration features, including SAML single sign-on, custom roles and permissions, data loss prevention, BYOK encryption, analytics, reporting, and dedicated support, are reserved for Enterprise custom pricing.
- ✗The value depends heavily on email volume; users who only handle a small number of messages each day may not recover enough time to justify the paid plan.
- ✗AI-generated replies, summaries, labels, and scheduling suggestions still require human review in sensitive client, legal, sales, recruiting, or executive communication.
Shortwave - Pros & Cons
Pros
- ✓Semantic search is meaningfully better than native Gmail search
- ✓Voice-matched drafts capture personal tone after short training period
- ✓AI Inbox bundling materially reduces newsletter noise
- ✓First-class mobile and web clients (parity, not afterthoughts)
- ✓Works on top of existing Gmail/Workspace — no migration
Cons
- ✗Gmail/Workspace only — no Outlook, no plain IMAP
- ✗Power users with multiple accounts hit Pro pricing fast
- ✗AI drafts can over-share context; review-before-send required
- ✗Mobile AI feature parity lags slightly behind web
- ✗Routing through third-party LLMs may not pass strict privacy reviews
