What Spark Mail is
What Spark Mail isSpark is an email client for individuals and small teams, built around a smart inbox that groups and prioritises mail, with shared drafts and comments for teams on top. The free tier is a complete client — unlimited accounts, unified inbox, calendar and the core productivity features — so the paid plans are mostly about AI meeting notes, templates and team collaboration depth. The AI meeting notes allowance is the sharpest line between the tiers: Plus gives you forty a month, and only Pro makes them unlimited.
What Superhuman is
What Superhuman isSuperhuman is a keyboard-first email client built around speed, with AI drafting and follow-up reminders. Everything is a keyboard shortcut and the interface is stripped to make triage fast, which is why heavy-volume users pay a premium for it. If your inbox is not the bottleneck in your day, that premium buys nothing.
