A professional with several mailboxes should count accounts, not just people. SaneBox's plan power-tool limits and Superhuman's Starter-versus-Business distinctions can matter more than an entry rate. Try a safe message, a reminder and colleague access in the proposed setup. A quieter view is not useful if an important reply or shared comment becomes hard to find.

Pros**Works with almost any mailbox:** Gmail, Microsoft 365, Exchange, iCloud, Yahoo, Fastmail and IMAP, in any email app.; **Cheap:** from $5.42 a month on annual billing, far below AI drafting assistants.; **Nothing to learn:** filtered mail goes to normal folders, and you train it by moving emails.; **Strong follow-up tools:** BCC reminders from any client, plus snooze folders.; **Header-only analysis:** SaneBox says it never stores email bodies or attachments.; **Clean exit:** cancelling can return everything to the inbox; 30-day money-back guarantee on request.**Built for speed:** keyboard-driven app with Split Inbox, Snippets, Send Later and read statuses for people who process lots of email.; **Strong follow-up tools:** Remind Me, Auto Reminders and (on Business) follow-up drafts in your voice.; **Real team features:** shared threads and comments that work even for colleagues who don't use Superhuman.; **Two ways to use it:** switch to the Mail app, or keep Gmail/Outlook and add the Email Assistant.; **Business is a bundle:** $33 a month (annual) includes Grammarly, Docs and the Go assistant as well as Mail.; **Clear AI data stance:** no training on your data, per Superhuman's help center, and a public DPA.
Cons**No AI writing:** it doesn't draft replies or take meeting notes.; **Features are rationed by plan:** Snack allows 2 power tools, Lunch 6 per account; everything needs Dinner ($26.58/mo annual).; **No free plan**, only a 7-day trial.; **Dated privacy paperwork:** privacy policy from February 2021 citing Privacy Shield; no SOC 2, ISO 27001 or stated EU residency.; **Business pricing isn't published:** team plans go through sales.; **Priced per email account:** more than 4 accounts means contacting support.**No free Mail plan**, and the billing FAQ says the suite has no free trials right now (only Email Assistant advertises 30 days).; **Pricier than inbox add-ons:** Starter alone is $25 per member a month on annual billing, and the most useful AI (Auto Drafts, Ask AI) needs Business.; **Only Gmail and Microsoft 365** accounts; no on-premises Exchange, IMAP or other providers.; **No stated EU data residency**; data may be processed in the US.; **Confusing packaging:** Mail plans, the Superhuman suite and Email Assistant overlap, so check exactly what your plan includes.; **SSO and SCIM need Enterprise.**

Which should you choose?

We would choose filtering alone when that is the unfinished job and a deliberate client change when it is not. Avoid paying for two overlapping triage approaches without a specific reason. These recommendations do not claim a measured typing-speed or inbox-productivity result from our use.
