Newton Mail
Newton Mail is a cross-platform email client with read receipts, snooze, send later, and shared threads for Gmail, Outlook, and IMAP
At $6.99/mo Pro, Newton is one of the cheaper ways to get automatic read receipts plus a genuinely unified multi-account inbox — Gmail and Outlook still don't do per-recipient open tracking natively. The 2026 additions (Tidy Inbox, Face ID and passcode lock, shared team mailboxes, the Claude Code-backed desktop Agent) close most of the gap with Superhuman and Spark. Teams sharing a support@ address get real delegation and admin controls at $15/user/mo.

Skip Newton Mail if you're content with free Gmail or Outlook and don't need read receipts, multi-account unification, or a shared team mailbox — the $6.99/mo Pro and $15/user/mo Team plans only pay off if you actually use those features daily.
Going past your tier's AI quota (20 actions/day free, 200/day Pro per seat) means you wait until it resets — there's no per-action overage purchase.
Newton's Free tier fits a single professional with up to 2 mailboxes; Pro at $6.99/mo is priced alongside paid clients like Spark Premium ($59.99/yr) while sitting below Superhuman ($25–30/mo) and Front ($19–59/user/mo). Team at $15/user/mo undercuts Front and Missive for small shared-inbox teams, but is more than the per-seat cost of Google Workspace itself — so it only makes sense if you're replacing a heavier helpdesk tool.

About Newton Mail
Newton Mail is a paid email client for Mac, Windows, iPhone, iPad, and Android that layers business-grade features on top of the mailboxes you already use. You connect Gmail, Google Workspace, Outlook, Microsoft 365, and IMAP providers like iCloud, Yahoo, and Fastmail, then work out of one unified inbox across every account and device. Cross-device sync covers settings, signatures, and snoozes, with Apple Handoff carrying a draft from phone to laptop. The features that justify leaving your native app: per-recipient read receipts that track every sent email automatically, send later for hitting another time zone's business hours, snooze presets that follow you between devices, and inbox rules that auto-archive, auto-label, or auto-forward across Gmail and Outlook from one setup. Templates with snippets kill repeat typing, and you can share any email as a public link that expires on your terms. Full-text search spans all accounts at once with operators like from:, to:, subject:, and has:attachment. Knowledge workers and small teams are the core audience. Shared threads let teammates comment and reply on your behalf with a full activity timeline, and the Team plan adds real Shared Inboxes for support@, sales@, or info@ addresses. Newton AI handles inbox triage and a compose-side writing assistant, metered at 20 actions a day on Free and 200 on Pro. An MCP server lets you search, read, draft, and schedule from Claude and other connected AI apps. The closest comparisons are Superhuman, Spark, and Shortwave. Newton's edge is breadth: it runs on more platforms, syncs read state and snoozes reliably, and comes in cheaper than most premium clients.
Behind the Verdict
The read-receipts pitch undersells what you actually buy. What keeps people on Newton is that read state, snoozes, signatures, and notification clears follow you across Mac, Windows, iPhone, and Android — archive a message on your laptop and the stale lock-screen alert disappears from your phone. That sounds minor until you've lived with a client that doesn't do it. We'd reach for Newton when you run three or more mailboxes and want one search bar over all of them, or when follow-up timing is part of your job. Sales, support, recruiting, and agency work all fit. The send-later and snooze combo is the practical fix for emailing clients in other time zones. Pass if email isn't a core workflow. The Free tier caps you at 2 accounts, 15 read receipts a month, and 20 AI actions a day; Pro at $6.99/mo removes those caps and adds unlimited templates. Annual billing saves 28%, which brings Pro under $61 a year — worth running the math before committing monthly. Against Superhuman, Newton is cheaper and runs on Windows and Linux, not just Mac and iOS. Superhuman still leads on keyboard-first speed and its own bundled AI. Against Spark, Newton's differentiator is receipts and, on Team, Shared Inboxes with send-as delegation rather than shared credentials. Two honest caveats. Team requires a 2-seat minimum, so solo users can't buy Shared Inboxes at all. And the desktop Agent runs through your own Claude Code installation rather than a bundled model — handy if you already pay for Claude Code, extra setup if you don't.

Real-world workflow fit
Concrete scenarios for the personas Newton Mail actually fits — and what changes day-one when you adopt it.
Connects both accounts, turns on read receipts, and schedules proposals to land at 9am in the client's time zone. Uses snooze to push a follow-up to Friday if no reply.
Outcome: Knows exactly who opened the proposal and when, sends the follow-up on time, all from one inbox without checking two apps.
Sets up a shared support@ team mailbox on the web, assigns send-as delegation, and configures shared templates for common replies. Admins update the alias, signature, and color centrally.
Outcome: The team replies from the team address without sharing a password, and every thread keeps an activity timeline the lead can review.
Runs Cmd+K, picks Agent, and asks 'what did Sarah say about the Q3 budget last week?' — Newton returns real mail rows and full messages from across all connected accounts.
Outcome: Gets the answer without switching apps or paying for a second AI subscription, since Agent runs through their own Claude Code install.
Use Cases
- Know when each recipient opened your email so follow-ups land at the right time
- Schedule emails to arrive in the recipient's working hours across time zones
- Comment on a shared email thread with teammates and keep a full activity log
- Run a shared support@ or sales@ mailbox as a team without sharing passwords
- Snooze emails across Mac, Windows, and mobile with the snooze synced everywhere
- Search across work Gmail, personal iCloud, and a Fastmail alias in one query
- Ask questions across all your accounts from Cmd+K using your own Claude Code install
- Filter Gmail Promotions/Social and Outlook's Other into a Low Priority view
Models Under the Hood
as of 2026-09-28
Limitations
- Newton's free tier is capped: 2 email accounts (Gmail, Outlook, or IMAP), 15 read receipts a month, and 20 AI actions a day.
- Pro at $6.99/mo billed monthly adds unlimited email accounts, unlimited read receipts, 200 AI actions a day, and unlimited templates.
- Shared team mailboxes and shared threads require a team/workspace setup rather than an individual plan.
- The desktop Agent/MCP integration depends on connecting Newton to Claude and other AI apps, so AI-assisted workflows rely on that external connection.

Free
$0
Ideal for
A single professional or curious user who wants to try Newton with up to 2 mailboxes before subscribing.
What this tier adds
Free entry point: 2 email accounts, 15 read receipts/month, 20 AI actions/day, 3 templates, full apps on Mac, Windows, iPhone, and Android.
Pro
$6.99/mo
Ideal for
Professionals who live in email, need unlimited accounts, and want every sent message tracked with read receipts.
What this tier adds
Adds unlimited email accounts, unlimited read receipts, 200 AI actions/day, unlimited templates, unlimited shared threads, and priority support over Free.
Team
$15/user/mo
Ideal for
Small teams running a shared support@, sales@, or info@ address who want delegation without sharing passwords.
What this tier adds
Adds shared inboxes (3 per workspace), send-as delegation, shared team templates, admin controls, and centralized billing on top of Pro — 2-seat minimum.
Where the pricing makes sense
The company stage and team size where Newton Mail's pricing actually pencils out — and where peers do it cheaper.
Newton's Free tier fits a single professional with up to 2 mailboxes; Pro at $6.99/mo is priced alongside paid clients like Spark Premium ($59.99/yr) while sitting below Superhuman ($25–30/mo) and Front ($19–59/user/mo). Team at $15/user/mo undercuts Front and Missive for small shared-inbox teams, but is more than the per-seat cost of Google Workspace itself — so it only makes sense if you're replacing a heavier helpdesk tool.
Setup time & first value
How long it actually takes to get something useful out of Newton Mail — broken out by persona, not the marketing-page minute.
Individual on Gmail or Outlook: 5–10 minutes — sign in with OAuth, connect accounts, toggle read receipts and dark mode. IMAP accounts (iCloud, Yahoo, Fastmail): 10–20 minutes depending on whether the provider requires an app password. Team plan: 30–60 minutes — an admin sets up the shared mailbox on the web, assigns delegation, and adds seats. Desktop Agent setup adds a few minutes if you don't
Switching to or from Newton Mail
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Gmail web/native: connect via OAuth, import signatures and aliases manually, keep Gmail as the backend so nothing is lost.
- →From Outlook / Microsoft 365: connect via OAuth, recreate signatures and signatures-per-account, run Inbox Rules to replicate folder automation.
- →From Apple Mail: add iCloud as an IMAP account, move rules over as Newton filters, and rely on full-text search to cover older mail.
- →From Superhuman: export any saved replies as Newton templates and rebuild read-receipt expectations around Newton's per-recipient tracking.
- →From Spark: reconnect Gmail/Outlook/iCloud directly, recreate snooze presets, and re-add connected apps like Todoist and Asana.
- ↗To Gmail native: your Gmail data already lives on Google's servers; turn off read receipts and re-create filters inside Gmail.
- ↗To Outlook native: your Microsoft 365 mail remains intact; port Newton templates into Outlook Quick Parts and rebuild rules.
- ↗To Superhuman: reconnect accounts directly, move Newton templates to Superhuman snippets, and expect different AI behavior.
- ↗To Spark: add accounts directly, recreate snooze presets and any connected-app shortcuts.
- ↗To Front or Missive (teams): export shared thread history where possible, replan shared inboxes against those tools' channel-based models.
