Cancellation service #1 in Singapore
Superhuman is a premium email client focused on speed, keyboard shortcuts, and productivity features such as AI-assisted tools, reminders, and shared team features.
It is subscription-based and available on web, iOS (App Store) and Android (Google Play), with pricing listed in USD on Superhuman's site.
Typical users are professionals who handle high email volumes and want faster workflows and integrations with CRM tools.
Feature sets differ by plan (Starter vs Business) and by platform (web vs mobile app billing).
Cancelling stops future renewals; you typically retain access until the end of the paid period you’ve already paid for.
If you cancel mid-period you will usually keep service until that period expires, per Superhuman’s terms.
Your account data (messages, settings) remains accessible while your account is active; data retention beyond that may follow Superhuman’s policies.
If you plan to leave, export or archive important information before access ends to avoid surprises.
Superhuman’s Terms state there are no refunds or credits for partially used subscription periods or unused capacity.
That policy is presented in section 8.10 of Superhuman’s Terms: Superhuman Terms.
Official Superhuman pricing is listed in USD only on their site. The table below uses the verified pricing and the provided USD→SGD conversion estimates.
Conversion estimates assume ~1 USD = 1.35 SGD; official billing is in USD.
| Plan | Price | Period | Features |
|---|---|---|---|
| Starter (monthly) | US$30 ≈ S$40.50 | Monthly | Access to Superhuman Mail, AI features, Share Availability, Shared Conversations, Team Comments |
| Starter (annual) | US$25/month ≈ S$33.75/month | Annual billing | Same as Starter (monthly), with 20% discount |
| Business (monthly) | US$40 ≈ S$54.00 | Monthly | Includes Starter features + Auto Drafts, Ask AI, CRM integrations, Recent Opens Feed |
| Business (annual) | US$33/month ≈ S$44.55/month | Annual billing | Same as Business (monthly), with ~17 - 18% discount |
Superhuman’s “no refunds” clause is stated to apply “to the fullest extent permitted by applicable law.” This means local consumer protection laws can override contractual no-refund clauses where applicable.
In Singapore, consumers retain statutory rights that may entitle them to remedies beyond a provider’s stated policy.
Many users try to cancel on the web after subscribing via the App Store or Google Play; that does not stop platform billing.
Always confirm which platform handled your payment before cancelling.
Expecting an automatic refund after cancelling is a frequent mistake - Superhuman’s Terms state no refunds for partial periods, and platform purchases follow platform refund rules.
Save confirmation messages and check platform refund procedures if you paid through Apple or Google.
| Plan | Price (USD) | Price (approx SGD) | Period | Key features |
|---|---|---|---|---|
| Starter (monthly) | US$30 | S$40.50 | Monthly | Core email, AI features, shared availability |
| Starter (annual) | US$25/month | S$33.75/month | Annual billing | Starter features, 20% discount |
| Business (monthly) | US$40 | S$54.00 | Monthly | Starter + Auto Drafts, Ask AI, CRM integrations |
| Business (annual) | US$33/month | S$44.55/month | Annual billing | Business features, ~17 - 18% discount |
Choose annual plans for meaningful discounts if you intend to keep the service long-term.
For short-term use or trialing features, monthly plans retain flexibility but cost more per month.
