Boomerang

Overview

Founded in 2010, Boomerang combines email productivity tools with meeting scheduling in browser extensions and mobile apps. It covers several stages of email work, from delaying a send and prompting a follow-up to snoozing messages or pausing incoming mail. Meeting tools add ways to find a time with a group or let others book one.

That breadth favors people who handle frequent correspondence and meeting coordination. If you only need to schedule an occasional email, Basic may be sufficient, but its monthly credit cap is easy to reach with repeated use. The plan choice also depends on account type: Personal is for Gmail addresses, while Basic, Pro and Premium support Gmail and Google Workspace accounts.

Key features

Email controls and writing help

Send Later, follow-up reminders, inbox snoozing, read receipts and Inbox Pause address different inbox tasks. Automated follow-ups and recurring emails make the toolkit relevant to repeat communication, while Respondable offers real-time AI help with making messages more actionable and selecting an appropriate tone. These tools are most useful when email is part of a daily workflow; they are more than an occasional send-later utility.

Basic counts messages scheduled with Boomerang features against 10 monthly credits. That is a meaningful constraint for anyone who relies on several of these controls throughout the month, so regular users are more likely to need a paid plan with unlimited credits.

Meeting coordination

Meeting Poll lets invitees vote on a time, while Bookable Schedule, Free/Busy sharing and Suggest Times cover other coordination needs. Bookable Schedule supports multiple calendars and integrates with Zoom and Google Meet on the Gmail product page; the Outlook product page describes support for multiple calendars, Microsoft Teams and Zoom. This makes Boomerang a stronger choice for people who want meeting coordination alongside email controls rather than a standalone scheduling tool.

Pricing

Boomerang uses a freemium model, with a free plan and a 30-day trial. The paid plan prices below are monthly amounts billed annually, so the annual billing term matters when comparing them with month-to-month services.

Plan	Price	What it includes	Best fit
Basic	Free	10 message credits per month; Gmail and Google Workspace accounts	Occasional use or a low-commitment way to try the email controls
Personal	4.98 USD per month, billed annually	Unlimited message credits; Gmail accounts; iPhone and Android apps	Individual Gmail users who want unlimited credits and mobile apps
Pro	14.98 USD per month, billed annually	Unlimited message credits; Gmail and Google Workspace accounts; advanced Inbox Pause and Respondable; recurring messages	Regular email users who need the advanced controls or recurring messages, including Google Workspace users
Premium	49.98 USD per month, billed annually	Unlimited message credits; Gmail and Google Workspace accounts; Track by Default; priority support; Toolbox; Salesforce/CRM integration	Users who need CRM integration, tracking by default or priority support

Basic trades unlimited use for a small quota. Personal removes the credit cap and includes mobile apps, but is limited to Gmail addresses. Pro adds advanced Inbox Pause and Respondable plus recurring messages, and supports Google Workspace; Premium is the tier for CRM integration and priority support. Enterprise is also an offering, with custom pricing, a dedicated customer success manager, onboarding, customized training and priority support. Boomerang says it has SOC 2 certification for enterprise security and compliance.

Platforms

Boomerang is available on Android, iOS, the web and as a browser extension. The plan details distinguish mobile-app access for Personal, which includes iPhone and Android apps, from the Gmail and Google Workspace account eligibility that separates the other tiers.

Who it's for

Boomerang fits people with crowded inboxes and professionals who routinely send follow-ups or coordinate meeting times. Its Outlook product page identifies sales and business people, small businesses, freelancers and executives as users. The combination is especially relevant when the same person needs inbox controls and ways to arrange meetings; someone who needs only one of those jobs may find a narrower tool a better fit.

Pros and cons

• Pros: Email scheduling, follow-ups, snoozing, read receipts and Inbox Pause cover several points in the inbox workflow.
• Pros: Meeting Poll, Bookable Schedule, Free/Busy sharing and Suggest Times add meeting coordination without leaving the broader email toolkit.
• Pros: Pro and Premium support Google Workspace as well as Gmail, and Premium adds Salesforce/CRM integration and priority support.
• Cons: Basic’s 10 monthly message credits limit its usefulness for frequent scheduling and other Boomerang-feature messages.
• Cons: Personal is restricted to Gmail addresses, so Google Workspace users need to choose another tier.
• Cons: Paid plans are billed annually, which is a commitment for users who are still deciding whether the extra controls justify regular use.

Verdict

Choose Boomerang if you are a Gmail or Google Workspace user who wants inbox controls, follow-up tools and meeting coordination in one toolkit. Its main strength is combining those everyday email and scheduling tasks; look elsewhere if you need a larger free allowance, a Gmail-only Personal plan does not suit your account, or annual billing is not right for you.
