Boomerang

Boomerang is an email productivity add-in for Gmail, Google Workspace, Outlook, and supported mobile clients. It helps people schedule messages, bring emails back at a chosen time, track replies, pause incoming mail, schedule meetings, and write more actionable messages with its Respondable AI assistant. It works inside the email workflow rather than replacing the user’s mailbox.

✨ Key Features

• Send Later — Schedule a composed email for a specific date and time, including natural-language timing such as “next Monday.”
• Follow-up reminders — Ask Boomerang to remind you when a message receives no reply, or remind you regardless of the response.
• Boomerang and snooze — Remove a message from the inbox and return it later at a chosen time.
• Response tracking and read receipts — Track whether recipients respond and, where enabled, whether sent messages are opened or clicked.
• Respondable AI assistant — Get real-time guidance intended to make an email clearer and more likely to receive a response; the service describes tone and effectiveness feedback.
• Inbox Pause — Pause new mail from appearing in the inbox, optionally with auto-reply and delivery exceptions; paid tiers add scheduled work hours, focus time, and batched delivery.
• Recurring Messages — Schedule repeated emails and reminders on a recurring cadence, available on documented Pro/Premium tiers.
• Bookable Schedule — Share available meeting times through a live calendar that can work with multiple calendars and supported video-meeting integrations.
• Suggest Times and Meeting Polls — Propose a meeting time in an email or coordinate invitees around a suitable slot.
• Share Free/Busy — Share availability without exposing the full details of a calendar.
• Calendar event creation — Turn an email into a calendar event from supported clients.
• Gmail and Outlook support — Use the browser extension/add-in with Gmail, Google Workspace, Outlook, or Office 365; mobile support depends on the client and subscription.

💳 Pricing

• Basic — Free; the official help pages describe 10 message credits per month and access to most basic features. Gmail/Google Workspace and Outlook availability differs by client.
• Personal — Paid tier with unlimited message credits and mobile-app access; the Outlook documentation describes it for Outlook.com addresses, while Gmail documentation describes it for Gmail addresses.
• Pro — Paid tier with unlimited message credits plus advanced Inbox Pause scheduling, Respondable machine-learning features, Recurring Messages, and other premium capabilities.
• Premium — Paid power-user tier; the Gmail documentation lists track-by-default, CRM integration, Boomerang Toolbox access, and priority support.
• Organizations — Organization subscriptions are available for teams, with centralized billing and management; the documented Gmail help page says Pro and Premium tiers can be used for organizations.

The reviewed official help pages do not provide a stable current dollar price table and carry different client-specific trial details. Confirm the live subscription page for monthly/annual prices, trial length, mailbox eligibility, included credits, organization minimums, taxes, and cancellation terms before purchase.
