Boomerang

Overview

Founded in 2010, Boomerang brings email controls, meeting coordination and writing guidance into browser extensions and mobile apps. That breadth suits professionals whose work involves both recurring correspondence and arranging time with others. It is less compelling for someone who only needs to schedule an occasional email.

Account choice matters: Personal is for Gmail addresses, while Basic, Pro and Premium support Gmail and Google Workspace accounts. The Personal plan also includes iPhone and Android apps. Check the plan’s eligibility before settling on a tier.

Key features

Email management

Send Later, follow-up reminders, inbox snoozing, read receipts and Inbox Pause address different parts of an email workflow. Automated follow-ups and recurring messages make the service useful for repeated outreach, while Inbox Pause can help people who need more control over incoming mail. The Basic plan’s 10 monthly message credits count messages scheduled with Boomerang features, so regular use can quickly outgrow the free allowance.

Meetings and writing

Meeting Poll lets invitees vote on a time; Bookable Schedule, Free/Busy sharing and Suggest Times cover other ways to find or offer availability. Bookable Schedule supports multiple calendars and, on Gmail, integrates with Zoom and Google Meet. Outlook’s product page describes Microsoft Teams and Zoom integrations. Respondable provides real-time AI guidance intended to help make emails more actionable and choose an appropriate tone. These tools make Boomerang broader than a send-later utility, though the most advanced Respondable features are reserved for Pro.

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 and customized training. That makes the higher-end offer more relevant to organizations needing implementation support than to individuals seeking basic email controls.

Pricing

Boomerang uses a freemium model and offers a 30-day trial. Basic is free and includes 10 message credits per month for Gmail and Google Workspace accounts. It is a useful low-commitment option for light use, but the quota is restrictive for people who schedule or automate messages regularly.

Personal costs 4.98 USD per month (billed billed annually). It provides unlimited message credits and iPhone and Android apps, but is limited to Gmail addresses. It fits individual Gmail users who need more than the free quota without the broader feature set of Pro.

Pro costs 14.98 USD per month (billed billed annually) and includes unlimited message credits for Gmail and Google Workspace, advanced Inbox Pause and Respondable, and recurring messages. It is the better fit for frequent email users who will make use of those advanced controls; it is a substantial step up from Personal, and Personal’s Gmail-only eligibility may make it unsuitable for some work accounts.

Premium costs 49.98 USD per month (billed billed annually). It adds Track by Default, priority support, Toolbox and Salesforce/CRM integration to unlimited credits, with Gmail and Google Workspace support. The extra cost is most defensible for teams or professionals who need CRM connectivity and priority help, rather than someone seeking only scheduling and inbox tools. The enterprise offering has custom pricing and includes a dedicated customer success manager, onboarding, customized training and priority support.

Platforms

Boomerang is available on Android, iOS, the web and as a browser extension. Mobile apps are included with Personal; Basic, Pro and Premium list Gmail and Google Workspace accounts as supported. Outlook has its own product offering, with scheduling integrations described for Teams and Zoom.

Who it's for

Boomerang is a sensible choice for sales and business professionals, small businesses, freelancers, executives and anyone with a crowded inbox who needs follow-up and meeting tools in the same workflow. Gmail users have the clearest path across its individual plans. It is a weaker fit for light users satisfied with occasional scheduling, or for people whose preferred account does not meet the chosen plan’s eligibility.

Pros and cons

• Pros: Email scheduling, reminders, snoozing, read receipts and Inbox Pause cover a broad range of everyday email tasks.
• Pros: Meeting Poll and several availability tools extend the product beyond email, with calendar, Zoom, Google Meet and Teams support described across its Gmail and Outlook offerings.
• Pros: Unlimited message credits on paid plans remove Basic’s monthly quota for users who rely on scheduled messages.
• Cons: Basic’s 10 monthly message credits can be limiting for regular use.
• Cons: Personal is restricted to Gmail addresses, while its higher price tiers are needed for advanced Inbox Pause, Respondable, recurring messages and CRM integration.
• Cons: Premium’s annual-billed price is difficult to justify for users who do not need its tracking, support or CRM features.

Alternatives

Email Scheduling Software is a useful starting point for comparing tools in this category. Choose Mixmax instead if its free allowance of 20 tracked emails per month and up to 50 sequence recipients better match your outreach needs; it also lists API, extension, Linux, macOS, web and Windows platforms.

FollowUpThen is worth considering for a simpler follow-up focus: its free plan allows 50 active followups per month and it supports Android, iOS and web. Yesware may suit readers prioritizing basic email-open and attachment tracking, with 10 campaign recipients per month and a Meeting Scheduler on its free plan.

Hunter is another freemium option, with a free plan of 50 monthly credits and one connected email account; its platforms include API, extension and web. Mailmeteor may be a better fit for Gmail, Sheets or Excel users who need a free 500 emails per month plus templates, tracking, scheduling and attachments.

Right Inbox offers a free plan with five emails per month for solo use, so it is an option for very occasional use. Scurry lists a free Seedling plan with 100 Acorns per month, three emails per sequence and one active workflow; it may suit readers who want a web-based workflow alternative. SendLater is a Windows-only alternative whose free plan schedules email once and limits resend delay to a maximum of four hours.

Verdict

Boomerang is best for Gmail users and busy professionals who want follow-up, inbox management and meeting coordination in one toolkit. Its strongest reason to choose it is the combination of email controls, scheduling and real-time writing guidance; its strongest reason to look elsewhere is the Basic quota and the cost of unlocking unlimited credits and advanced features. For light use, Basic may suffice, but frequent users should weigh the annual-billed plan costs against the specific Pro or Premium capabilities they need.
