How STAMP stacks up.
Every other email app is either a faster reader for all of it, or a cloud AI layer reading your mail to summarize it. STAMP triages on-device and shows you only what needs a reply today. Here is the honest comparison against the tools people actually switch from.
| Category | Most email clients | STAMP |
|---|---|---|
| Triage | A faster way to read all of it | Urgent-first, seven threads a day |
| Classification | Cloud AI reads your mail to summarize it | Runs on-device, nothing leaves your Mac |
| Accounts | One provider, or a shallow unified inbox | Unlimited accounts, one real window |
| Pricing | Free with ads, or $20 to $30 a month | $9 a month, locked at founding rate for life |
