Pick Spark if you want a smart, affordable email app with strong team collaboration and a generous free tier.
Pick Superhuman if you want the fastest, most polished, keyboard-driven email experience and will pay a premium.
Spark and Superhuman are both modern email clients that sit on top of your existing accounts, but they target different priorities. Spark offers a smart, organized inbox with priority sorting, team features like shared drafts and comments, and a generous free tier, making it a strong value for individuals and teams. Superhuman is the premium speed play: a meticulously fast, keyboard-driven experience with shortcuts, AI assistance, and a polished feel that power users find addictive — at a premium price.
On price, Spark is free to start with Premium from around $8 a month, while Superhuman is around $30 a month. The choice is mostly smart, affordable, team-friendly email (Spark) versus the fastest, most polished power-user client (Superhuman).

Things neither product's marketing page leads with.
Spark is a great value with team features, but it is not as relentlessly fast or premium-feeling as Superhuman.
Superhuman is the fastest, most polished client, but it costs far more and lacks Spark's collaboration and free tier.
For value and teamwork Spark wins; for speed and polish Superhuman wins.
