What Each One Actually Is
Missive
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.
- 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) |
Polymail
A clean, sales-oriented client with Email Tracking, Follow-up Reminders, and Premium Sequences. But sync issues and weak support are the recurring complaints.
- Polished, easy-to-use design—clean interface and quick onboarding are the default praise on G2.
- Email Tracking and read receipts genuinely work, letting sales tell “opened but no reply” from “never opened.”
- Automated Sequences chase non-responders on a schedule (Premium tier).
- Follow-up Reminders are simple and reliably useful for not letting leads slip.
- Calendar Scheduling drops a booking link into emails and cuts down on scheduling back-and-forth.
| Plan | Price |
|---|---|
| Basic | $10/user/mo annual ($13 monthly) |
| Premium | $24/user/mo annual ($29 monthly) |
| Enterprise | Custom pricing |
Where Missive Wins
Polymail is lovely to look at until you try to run a shared inbox on it. In testing I handed a shared lead queue to two reps in Polymail. No assignment, no internal note attached to a thread, no way to stop both people replying. The tracking data was useful, but coordination was nonexistent. Moving the same queue to Missive, I routed inbound leads by keyword, left internal comments on each thread, and co-drafted replies together. The shared inbox finally behaved like a team workspace, not two separate inboxes pointing at the same account.
Missive’s channel breadth is the other gap Polymail can’t close. Connecting WhatsApp and Messenger meant inbound leads from any channel hit the same assigned queue. Polymail is email-only, and its recurring sync complaints (dropped messages, ‘not all emails synced’) make it risky as a system of record for a shared queue.
Where Polymail Wins
For outbound sales, Polymail’s tracking is the thing you feel every day. I sent 40 cold emails through it. The read receipts lit up in real time, so I could instantly tell ‘opened three times, no reply’ from ‘never opened’ and prioritize my follow-up. Follow-up reminders nudged me when a lead went quiet, and the calendar scheduling link let prospects book a call without a single scheduling email back and forth. For a solo AE, that loop is worth the subscription on its own.
The catch is well documented: sync bugs and weak support. Reviewers repeatedly report dropped emails and having to type a contact’s whole name to find them. On Premium ($24/user/month), automated sequences chase non-responders on schedule — genuinely useful, but locked behind the higher tier. There’s no AI, which increasingly stands out next to competitors.
The Price Math
Solo user (1 person, 1 year)
Missive Starter billed annually: $14/user/mo. But it is a team tool; solo sales use wastes the collaboration — $14 x 12 = $168/yr.
Polymail Basic billed annually: $10/user/mo. Sequences require Premium at $24/user/mo — $10 x 12 = $120/yr (Basic) or $24 x 12 = $288/yr (Premium).
Verdict: For a solo rep, Polymail Basic is $48 cheaper and gives you the tracking and follow-up Missive lacks. If you need sequences, Polymail Premium at $288/yr still buys an outbound workflow Missive simply does not have.
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.
Polymail Basic at $10/user/mo annual for 5 seats; no shared inbox, no assignment, stacking individual licenses — $10 x 5 x 12 = $600/yr.
Verdict: Polymail looks $840 cheaper, but it is five separate sales licenses, not a shared inbox — your team still needs another tool for inbound coordination. Missive’s $1,440 is the complete team system.

Frequently Asked Questions
Is Polymail or Missive better for sales?
Polymail. Its read receipts, follow-up reminders and automated sequences are purpose-built for outbound reps, and no shared-inbox overhead gets in the way. Missive has no tracking or sequences at all.
Is Missive a good Polymail alternative for a team?
Yes — if the team need is a shared inbox rather than outbound sales. Missive adds assignment, internal chat, co-drafting and multi-channel, none of which Polymail offers. It doesn’t replace Polymail’s tracking and sequences, though.
Does Polymail have shared inboxes?
Not in any meaningful sense. You can stack individual seats, but there’s no shared inbox, no assignment and no internal team chat threaded to messages. Teams that need those features will outgrow it fast.
Which has AI?
Missive. Its AI Assistant drafts, summarizes and translates via credits or your own OpenAI/Anthropic/Gemini key. Polymail currently ships no AI features, which reviewers increasingly call out as a gap.
