Spark Mail
Email client with a unified smart inbox, AI tools and team features
Which one is for you
Pick Spark Mail if
- Fits if you juggle several email accounts and want them in one inbox on desktop and phone
- Works for anyone who wants snooze and send later without paying
Look elsewhere if
- Skip it if you need email in a browser or on Linux, as there's no version for either
- Not for you if you want AI drafting for free, because Spark +AI needs Plus or higher
- Pricey if you only need a shared support@ inbox, since that sits on Pro at $16.58 a user
- Tight if you lean on the free AI: 5 meeting notes in total and 1 month of history for the Assistant
- Watch out: the 7-day trial applies only when you subscribe in the app, and monthly billing costs 17% more
Pick Twobird if
- Fits if you keep Gmail or Outlook and want notes and reminders in the same app
- Works for people on web and iPhone who want a free client
Look elsewhere if
- Skip it if your mail isn't on Gmail or Outlook
- Skip it if you use Android, as no Android app is listed
- Not for you if you want a kept-up app, as the site shows 2022 and the iOS app was last updated in March 2022
- Watch out: the vendor says paid plans may come later

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.
