How we grade them
| 3.8GPASpark MailExcellent | 2.4GPASuperhuman MailFair | |
|---|---|---|
| Value for money | BPlus is $8.25 a user a month billed annually, which is $99 a year, or $10 monthly. That's about what paid email apps usually start at, and it adds Gatekeeper, Priority and the AI tools. Shared inboxes need Pro at $16.58. | C$25 a month for an email app is a lot when Gmail is free. It can pay for itself if email is your job. For most people it won't. |
| Free plan and trial | AUnlimited email accounts in one Smart Inbox, with snooze, send later, reminders and a calendar, free for good. Most people could stop here. The AI on Free is only a taster: 5 meeting notes in total, and 1 month of history for the AI Assistant. | FThere isn't one. No free plan, and the pricing page doesn't mention a trial, so you pay to find out. |
| Features | AA unified inbox that separates personal mail from newsletters, Gatekeeper to screen new senders, AI that drafts, summarizes and translates, and a built-in calendar. Teams can share a thread, comment on it privately and write the reply together. | ASplit Inbox, a shortcut for everything, reminders, AI writing and summaries, shared threads and a built-in calendar. It's a lot of email app. |
| Ease of use | A4.6 from about 82,600 App Store ratings. Add your accounts and the Smart Inbox does the sorting for you. Snooze and send later are there from the start, on the free plan. | BQuick once the shortcuts sink in, and one reviewer says ten minutes did it. You do have to learn its way of doing things. |
| Platforms and integrations | AMac, Windows, iPhone and Android, and it takes Google, Outlook, iCloud, Yahoo, Exchange and IMAP accounts. Paid plans plug into Todoist, Asana, Trello, Notion and Slack. There's no web version and nothing for Linux, mind. | BMac, Windows, iPhone, Android and a Chrome extension for the web. Only for Gmail and Outlook accounts, though. |
| Best for | one inbox for all your email accounts | people who live in their inbox |
