Newton Mail
Cross-platform email app with read receipts, snooze and send later
Which one is for you
Pick Newton Mail if
- Fits if you want the same mail app on Mac, Windows, iPhone and Android
- Works for anyone who needs to know whether a sent email was opened, and by which recipient
Look elsewhere if
- Tight if you're staying free with more than 2 accounts, 3 templates or 15 read receipts a month
- Skip it if you check mail in a browser, as there's no webmail, only a settings portal
- Pricey if you only need a shared inbox: that's Team at $12 a user, 2 seats minimum, by request
- Watch out: the 14-day trial's terms aren't spelled out, and Pro is $6.99 billed monthly, not $5
- Watch out: a Linux build is linked from the homepage, but the pricing page lists no Linux app
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

|---|---|---|
| Value for money | CPro is $5 a month billed annually, $6.99 monthly, which is the ordinary band here, under the $8 middle but above the cheapest quarter.

| Features | BPer-recipient read receipts with nothing to switch on, snooze, send later, templates, full-text search across every account, a Today view that triages by priority, one-click saving to Todoist, Trello or Asana, and an MCP server so Claude can draft and schedule mail.

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.
