Which one is for you
Pick Superhuman Mail if
- Fits if you get a high volume of email on Gmail or Outlook and want to work through it from the keyboard
- Works for teams that share and comment on threads instead of forwarding them
Look elsewhere if
- Skip it if you get twenty emails a day, as Gmail's own app costs nothing
- Tight if you want to try before you buy: there's no free plan and the pricing page mentions no trial
- Pricey if you mainly want AI drafts or CRM links, since Auto Drafts, Ask AI and HubSpot need Business at $33
- Not for you if your email isn't on Gmail or Outlook, as no other providers are listed
- Watch out: both plans stop at 25 seats, SSO and SCIM are Enterprise only, and Enterprise has no published price
Pick Zero Mail if
- Fits if you want AI summaries and replies over a Gmail or Outlook inbox
- Works for developers who are happy with a beta and might self-host
Look elsewhere if
- Skip it if you want a finished product, because the site labels Zero beta
- Tight if you have more than one inbox, since free allows one connection
- Pricey if you want the full AI writing and summaries: Pro is $20 a month
- Watch out: no desktop or phone apps are listed, only the web
- Watch out: the pricing page does not say whether $20 is monthly or annual

More comparisons
How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
