Rythm vs Superhuman — protection vs speed.
Superhuman makes email faster with a premium client. Rythm makes email safer with a bouncer at the door. Different categories, different problems. Rythm is roughly 18× cheaper and runs inside the inbox you already use.
Superhuman makes email faster. Rythm makes email yours.
Different categories
Superhuman is a client. Its value prop is speed: keyboard shortcuts, instant search, scheduled sends, read receipts, a polished UI. If you live in email all day and want the interaction loop tightened, that’s its job.
Rythm is a protection layer. Its value prop is: unknown senders pay a small cover charge to reach you; known senders walk right in. It runs on top of Gmail or Outlook and lets you keep whatever client you prefer.

Can you use both?
Yes. They don’t conflict. Superhuman is a Gmail/Outlook client, and Rythm is a Gmail/Outlook filter. If you use Superhuman as your client, Rythm still operates on the underlying account — paid emails arrive labeled RYTHM: PAID, rejected senders go to the RYTHM: REJECTED folder, and all of that shows up in Superhuman just like it would in Gmail.
Some users will pay for both. Most will pick one based on their actual problem: is email too slow, or is email too crowded?
Pricing
Superhuman is $30/month ($360/year). Rythm is $1.65/month (~$21/year). That’s about 18× cheaper. Rythm also pays you when strangers send email worth charging for.
FAQ
If I use Superhuman, can I still use Rythm?
Yes. Superhuman is a client that connects to your underlying Gmail or Outlook account; Rythm is a filter that operates on that same account. The Rythm labels appear in Superhuman because they’re native Gmail/Outlook labels.
Does Superhuman include inbox protection like Rythm?
Not at the same layer. Superhuman has VIP sorting, split inbox, and a few spam-adjacent features — but it inherits Gmail/Outlook spam filtering for strangers. There’s no cover charge, no guest list, and no “strangers pay you” mechanic.
What if I can’t justify $360/year for a client?
Then you’re probably not the target. Rythm’s $21/year covers the inbox-protection problem for vastly more people — and pays for itself after ~1.4 paid strangers a day.
Is Rythm trying to replace Superhuman?
No. Different problem. Rythm doesn’t compete on keyboard shortcuts, undo send, or read-receipt tracking. It competes on: who gets to reach your inbox in the first place.
Does Rythm work with mobile Gmail / Outlook apps?
Yes. Rythm operates on the account, not on the client. Any Gmail or Outlook client — desktop, web, mobile — will show the Rythm labels correctly.
Different problem. One-eighteenth the price.
