Shortwave Review

Shortwave is an AI-native email client that sits on top of Gmail and tries to do the reading, sorting, and drafting for you. It is a productivity tool rather than an outreach tool, and it prices accordingly. This review covers what the product actually does, what the current per-seat math looks like, and where we could not verify vendor claims independently.

Verdict at a glance

What kind of tool is Shortwave?

Shortwave replaces the Gmail interface with its own client on iOS, Android, Mac, and Windows, and layers an AI assistant across the whole mailbox. The assistant is the product. It answers questions about your mail in natural language, pulls facts out of attachments, proposes snoozes, and drafts replies in a style learned from what you have written before.

The organizational layer is the second half. Split inbox tabs group mail into separate views, bundle triage clears whole categories at once, and filters are written as plain English instructions rather than rule-builder syntax. Multiple Google accounts connect under one plan.

For teams, Shortwave adds shared threads with real-time updates, private comments inside a thread, assignment with progress tracking, and shared labels that turn a team's mail into a searchable archive. That is closer to a light shared-inbox tool than a full help desk, but it covers the common case of two or three people coordinating on the same conversations.

How it works

Setup is trivial: authorize a Google account, let it index, and the assistant becomes available. There is no domain configuration and no sending reputation to manage, because Shortwave sends through your existing Gmail account.

The automation ceiling is raised by Tasklet, Shortwave's sister product, which the company positions as always-on workflow automation — drafting replies automatically, posting team comments, and connecting to a broad catalog of third-party apps. It is advertised as an integration rather than an included feature, so treat it as a separate line item until you confirm otherwise at checkout.

Shortwave pricing (2026)

A 14-day trial is offered on all plans with no card required, and there is no permanent free tier on the current pricing page.

The real-cost notes worth doing before you commit:

• This is per seat. A three-person team on Business is $90 a month, or $1,080 a year. The same team on Premier is $1,620. On Max it is $4,320 — for three people's email.
• The tiers sell AI quota, not features. The functional differences are usage caps, search history depth, filter counts, and how many threads a single AI search can read. If your team is light on AI use, Business is the honest starting point and the expensive tiers buy headroom you may not touch.
• Daily quotas are approximate. The vendor describes Business as roughly 150-300 requests per day, varying by request complexity, so validate your real consumption inside the trial.
• No annual pricing is published on the current page. Lower per-seat figures circulating elsewhere appear to be stale; the monthly rates above are what the vendor lists today.

What we could and couldn't verify

The pricing, plan limits, platform support, and feature list above come from Shortwave's own site, fetched fresh. Everything attributed to the vendor should be read as a vendor claim — particularly the AI quality and time-savings language, which is not independently measurable.

What we could not verify is third-party sentiment. G2 and Trustpilot both refused automated access, and we found no accessible review base with a meaningful count for this product. We are not going to invent a rating or paraphrase reviews we did not read. Plainly: as of this writing, there is no independent review data on this page, and if that matters to your purchase decision, the 14-day trial is the only evidence you can trust.

Pros and cons

Pros

• Genuinely useful conversational search over years of mail and attachments
• Plain-English filters instead of rigid rule builders
• Native apps on iOS, Android, Mac, and Windows
• Multiple Google accounts under a single plan
• Team features (shared threads, comments, assignment) without a help-desk migration
• Trial requires no payment details

Cons

• Gmail only — no Microsoft 365, Outlook, or generic IMAP
• Per-seat pricing gets expensive fast for teams
• Higher tiers mostly sell AI quota rather than new capability
• Daily request limits are described as ranges, not guarantees
• No permanent free plan
• No independently verifiable review base

Shortwave alternatives

• Superhuman — the original speed-first premium email client; strong keyboard workflow, less emphasis on conversational AI search.
• Missive — team-inbox focused, with chat and assignment built in; better if collaboration matters more than a personal AI assistant.
• Front — the heavier shared-inbox and customer-communication platform; more capable, more expensive, more implementation work.
• Spark Mail — cheaper AI-assisted client with broad provider support including Outlook and IMAP.
• Gmail with Gemini — the zero-migration option; weaker cross-mailbox reasoning, but already in the price of Workspace for many teams.

Who should use Shortwave — and who shouldn't

Good fit: Gmail-based founders and executives whose inbound volume is the actual bottleneck in their day; small teams that want shared threads and assignment without adopting a support desk; anyone who repeatedly needs to find something buried in years of mail and finds Gmail search inadequate.

Poor fit: anyone on Microsoft 365, Outlook, or IMAP, since the product simply does not support them; teams that will not use AI heavily enough to justify per-seat pricing above a basic client; and cold outreach operators — Shortwave is built for the mail arriving in your inbox, not for sending sequences out of dedicated sending accounts.
