Boomerang

Overview

Founded in 2010, Boomerang brings email timing, inbox management, follow-up, and meeting coordination together in browser extensions and mobile apps. Rather than focusing only on scheduled sending, it covers several recurring email tasks and offers tools for arranging meetings around invitees’ availability.

The account requirements matter: Personal is for Gmail addresses, while Basic, Pro, and Premium support Gmail and Google Workspace accounts. That makes Personal a poor fit for a Google Workspace user, even though it is a low-cost paid tier.

Key features

Email controls and follow-up

Send Later, follow-up reminders, inbox snoozing, read receipts, and Inbox Pause address different stages of email work. Automated follow-ups and recurring emails also suit repeat communication. The breadth is a practical advantage for people who regularly send, track, and revisit messages; it is more than an occasional scheduler requires.

Respondable uses AI to provide real-time help with making emails more actionable and choosing a tone. That may help users who want guidance while composing, though advanced Respondable is reserved for Pro. Inbox Pause is another graduated feature: the tool appears among the email features, while advanced Inbox Pause is included with Pro.

Meeting coordination

Meeting Poll lets invitees vote on a time, while Bookable Schedule, Free/Busy sharing, and Suggest Times cover other scheduling needs. Bookable Schedule supports multiple calendars and integrates with Zoom and Google Meet on the Gmail product page; the Outlook product page names Microsoft Teams and Zoom. This gives Boomerang a useful role when email follow-up and meeting coordination sit in the same workflow.

Security and support

Boomerang says it has SOC 2 certification for enterprise security and compliance. Premium includes priority support; the enterprise offering adds a dedicated customer success manager, onboarding, customized training, and priority support. Those services are more relevant to organizations seeking a supported rollout than to an individual choosing a low-cost plan.

Pricing

Boomerang has a freemium model, a free plan, and a 30-day trial. The paid prices below are billed annually, so their monthly figures should be read as annual-billing rates rather than month-to-month prices.

Basic is the only free tier and its 10-credit monthly ceiling makes it best for occasional use, not sustained high-volume scheduling. Personal removes that quota but narrows eligibility to Gmail. Pro and Premium extend support to Google Workspace and add higher-tier features; the choice between them turns on whether Premium’s Track by Default, Toolbox, Salesforce/CRM integration, and priority support matter to the user.

Platforms

Boomerang supports Android, iOS, browser extensions, and the web. Personal specifically includes iPhone and Android apps. The range gives mobile users access alongside browser-based email work, while the plan’s account eligibility still determines whether the service is a fit.

Who it's for

Boomerang is a strong fit for sales and business people, small businesses, freelancers, executives, and anyone dealing with a crowded inbox. Its follow-up reminders, recurring emails, and meeting tools are especially relevant when correspondence and scheduling are routine parts of the day. Someone who only needs to send an occasional message later may find the broader toolkit—and the paid plans needed to escape Basic’s credit cap—unnecessary.

Pros and cons

• Pros: Email timing, follow-up, snoozing, read receipts, and Inbox Pause cover several inbox tasks in one toolkit.
• Pros: Meeting Poll and multiple scheduling options support both group availability and individual booking.
• Pros: Personal offers unlimited message credits and mobile apps at 4.98 USD per month billed annually.
• Cons: Basic allows only 10 message credits per month, limiting its usefulness for frequent scheduling.
• Cons: Personal supports Gmail addresses only, so Google Workspace users must consider another plan.
• Cons: Annual billing applies to the stated paid monthly prices, and Pro or Premium costs more for advanced features and support.

Alternatives

Email Scheduling Software is a useful starting point for comparing tools in the category.

Choose FollowUpThen if a free forever allowance of 50 active followups per month is a better match than Boomerang’s 10 monthly message credits. Its free plan also supports Android, iOS, and web.

Saleshandy is a paid alternative with a free trial and plans built around prospects and monthly email volume; its Starter plan includes one user, 2,000 active prospects, and 6,000 emails per month.

Hunter offers a free plan with 50 monthly credits, Basic Discover filters, one connected email account, and 500 recipients per sequence. Consider it when those limits and its web, extension, or API platforms better suit the task.

Mailmeteor may suit Gmail, Sheets, or Excel users who want a free 500-email monthly allowance with templates, tracking, scheduling, and attachments; it runs on web and as an extension.

Mixmax is another option when tracked email volume or sequences are the priority: its free plan includes 20 tracked emails per month and up to 50 sequence recipients per month.

Right Inbox has a free Limited plan for solo use, capped at five emails per month and excluding Mail Merge, Email Sequences, and CRM Integration.

Scurry offers a free Seedling plan with 100 Acorns per month, three emails per sequence, and one active workflow for web users.

SendLater is a Windows option if scheduling email once and a resend delay of up to four hours are sufficient; its free plan is limited to those functions.

Verdict

Boomerang is best for Gmail and Google Workspace users who regularly manage follow-ups, crowded inboxes, and meeting coordination. Its main reason to choose it is the combination of email controls and scheduling tools, backed by mobile and browser access. Look elsewhere if the 10-credit free cap is too restrictive, your account does not qualify for the plan you want, or you need only occasional send-later functionality.
