Missive vs Shortwave

Missive

• Small teams sharing addresses such as support@ or sales@
• Teams that want to discuss emails internally instead of forwarding them
• Businesses that also talk to customers over SMS, WhatsApp or live chat

Shortwave

• Gmail and Google Workspace users who want AI to triage and draft email
• Teams that want to comment on and assign email threads internally
• People who want Google Inbox-style bundles on top of Gmail

Missive

• There is no free plan; once the 30-day trial ends a paid plan is required.
• Starter is limited to 5 users and leaves out integrations, rules, API access, the AI assistant and analytics.
• SAML single sign-on and IP restriction are only available on Business.
• Missive says it offers no discounts for students, nonprofits or schools, and yearly plans are not refundable.

Shortwave

• Sign-in requires Gmail or Google Workspace. Microsoft 365 and Exchange are not supported, and other providers only work by forwarding mail to Gmail.
• Paid plans start at $18 per seat a month for individuals and $30 on the business plans, and AI usage on every plan is capped by a daily quota.
• The Business plan limits AI search to 5 years of history and allows 3 AI filters.
• Native apps cover Mac, Windows, iOS and Android; other platforms rely on the web app.

Missive

Shared inboxes and team spaces

Team inboxes sit next to personal accounts, grouped into team spaces. Conversations can be assigned to a person or a team, with controls over who sees what.

Internal discussion in threads

Teammates talk about an email in an internal conversation attached to the thread, so nothing has to be forwarded or CC'd.

Collaborative drafting

Several people can write the same reply together in real time before it is sent.

Rules and automations

Automate repetitive handling such as assigning or tagging with up to 1,000 rules. Rules are available from the Productive plan.

Multi-channel inbox

Email from Gmail, Microsoft 365, iCloud or any IMAP account appears alongside SMS, WhatsApp, Messenger, Instagram and live chat conversations.

AI assistant and integrations

An AI assistant drafts and translates replies and can pull context from connected tools over MCP. It comes with Productive, along with 25+ app integrations and the API.

Shortwave

AI assistant

Prompt the assistant to organize the inbox, write in your own voice, search mail or schedule a meeting. It can also browse the web and analyze attachments.

AI filters

Describe a rule in plain English and it labels, stars or archives incoming mail. Business includes 3 AI filters, Premier 10 and Max 50.

Split inbox and bundles

Divide the inbox into tabs by sender, label or custom query, and triage promotions, newsletters and updates in bulk as bundles.

AI search

Ask questions across your mail instead of keyword searching. Business reaches back 5 years and reads up to 50 threads per search; Premier removes the history limit.

Team collaboration

Share a live thread with teammates, discuss it in private comments, assign emails with a done status, and keep shared labels, snippets and saved prompts.

Scheduling and follow-ups

The assistant checks availability, creates calendar events and writes scheduling emails. Snooze, delivery schedules and no-reply reminders are also included.
