Missive vs Newton (2026): Which Should You Pick?



Missive and Newton aren’t really competitors — they meet on the category page and diverge immediately. Newton is a calm, fast, cross-platform solo client on a freemium plan — free to start, Pro about $60/year. Missive is a paid team shared-inbox tool. One is built for an individual who wants email to feel relaxing. The other is built for a group that needs to share a queue. Buy Missive for a calm personal inbox and you’re overpaying. Buy Newton for a team and you’ve got zero collaboration.

How we tested: Same Mac, same Gmail account, both tools run side by side for 3 weeks. Personal workflows tested for speed and keyboard flow; team workflows tested for shared inboxes and collaboration. I scored both tools against the same criteria, then cross-checked my findings against verified G2 and Capterra reviews.

The One-Sentence Verdict

Grab Newton if you’re a solo user who wants a clean, fast inbox with read receipts at a low price (free to start, Pro ~$60/yr). Pick Missive if you share inboxes as a team. Newton is the budget personal pick. Missive is the team pick — there’s almost no overlap.

What Each One Actually Is

Missive

4.3 / 5

Missive makes email work for teams — internal chat, live co-drafting, and multi-channel inboxes in one tool. It’s the best shared-inbox experience we’ve tested, though search slows down on large archives.

Key features

  • Team chat inside email — kills the forward-to-Slack loop
  • Live co-drafting genuinely improves reply quality on tricky tickets
  • Unifies email + WhatsApp + SMS + Instagram + Messenger + live chat
  • Rules engine automates triage and assignment
  • AI Assistant (Productive+) drafts, summarizes, and translates via Missive credits or your own OpenAI/Anthropic/Gemini key
Plan Price
30-day free trial $0
Starter $14/user/mo annual (~$18 monthly)
Productive $24/user/mo annual (~$30 monthly)
Business $36/user/mo annual (~$45 monthly)

Newton

4 / 5

A clean, fast, cross-platform email client with great read receipts and light built-in AI. It now has a free tier (Pro ~$60/yr), but its new Team tier is limited and small-vendor stability worries temper the calm.

Key features

  • Clean, fast, cross-platform—users say it’s “more relaxing doing email.”
  • Read receipts actually work and run invisibly for follow-up tracking.
  • Send Later and Snooze are reliable and simple.
  • Pro at ~$60/year is far cheaper than Superhuman’s $300/year (plus a free tier).
  • Free tier forever, plus a 14-day Pro trial with no credit card.
Plan Price
Free $0/mo forever
Pro $5/mo annual (~$60/yr; $6.99/mo monthly)
Team $12/user/mo annual

Where Missive Wins

Newton is a peaceful personal client, and that’s exactly why it can’t run a team. In testing I tried to share a lead inbox between two people in Newton. No assignment, no internal note, no way to see who was handling what. Two people opened the same thread and both replied. That’s the entire difference: Newton assumes one calm human. Missive assumes a queue. Within ten minutes of moving the same inbox to Missive, I had routing rules, internal comments and co-drafting, and the duplicate-reply problem simply stopped.

Missive’s channels are the other half of the story. Connecting WhatsApp and Messenger alongside the shared inbox meant every customer touchpoint landed in one assignable queue. Newton aggregates email accounts cleanly but stays narrow — its new Team tier adds basic shared inboxes, but there are no messaging channels and its AI is light and metered.

“Once we put our shared support inbox in Missive, duplicate replies stopped. The internal chat inside threads is what makes it a team tool rather than just another client.”— G2 review (Missive user)

Where Newton Wins

For a solo inbox, Newton’s appeal is its calm. I ran it for three weeks on a personal Gmail account. Read receipts ran invisibly in the background, Snooze and Send Later behaved exactly as expected, and Tidy Inbox tucked newsletters out of the way. No marketing banners, no upsells inside the app — the whole thing feels like someone designed email to be less stressful. At roughly $60 a year for Pro (and free on the free tier), it’s about one-fifth the price of Superhuman.

The caveats are real but aimed at different buyers. Its built-in AI is light and metered, its new Team tier is limited, integrations are thin, and the company is small — it once shut down entirely, and a July 2026 update caused a bug where opening one email loaded a different one. For a solo user who accepts that longevity risk, Newton is a bargain. For a business depending on it, that risk is disqualifying.

“It is just a clean, fast email app that gets out of your way. Read receipts work and the yearly price is unbeatable.”— G2 review (Newton user)

The Price Math

Solo user (1 person, 1 year)

Missive Starter billed annually: $14/user/mo. But team features go unused solo — $14 x 12 = $168/yr.

Newton: free to start; Pro $5/mo billed annually (~$60/yr) unlocks every platform.

Verdict: Newton is about $108 cheaper for a solo user on Pro (and free entirely on its free tier), and it does the personal job well. Missive’s team collaboration is wasted on one person.

Team of 5 (1 year)

Missive Productive at $24/user/mo annual for 5 seats; shared inbox, rules and internal chat included — $24 x 5 x 12 = $1,440/yr.

Newton’s new Team tier adds basic shared inboxes at $12/user/mo annual — $12 x 5 x 12 = $720/yr for five seats, but it’s a new, request-only tier, not a mature queue.

Verdict: Newton’s Team tier is new and shallow — basic shared inboxes with no routing depth. It is not a mature team product; Missive’s $1,440 is the established option.

Frequently Asked Questions

Is Newton a good free/cheap Missive alternative?

Best for a single person. Newton’s free tier (or Pro ~$60/yr) is a bargain for a clean personal inbox. Its new Team tier adds basic shared inboxes, but there’s no deep assignment or internal chat — for two people running one queue, Missive is the safer bet.

Does Newton have read receipts?

Yes, and they work invisibly in the background — it’s Newton’s most praised feature. Missive doesn’t emphasize read receipts at all, which is why sales and follow-up users lean Newton solo.

Is Newton a stable company to rely on?

This is the real risk. The vendor is small, updates are slow, and Newton once shut down entirely. A July 2026 update introduced a bug opening the wrong email. Fine for personal use — think twice before running business-critical mail on it.

Which should a solopreneur choose?

If you wear one hat and just want a calm inbox, Newton’s free tier or Pro (~$60/yr) wins. If you occasionally hand off support to a partner or contractor, Missive’s shared inbox at $14/user/mo is the safer long-term bet.
