Boomerang vs Alternatives: Full Comparison

Email scheduling and management tools have become essential for professionals seeking to maximise productivity and control their inbox. Boomerang has long been a favourite, but a host of alternatives now offer compelling features that may better suit your workflow. This comprehensive comparison examines Boomerang against its top competitors in 2025, covering features, pricing, and suitability for different use cases.

What Is Boomerang and How Does It Work

Boomerang is a browser extension and mobile app that integrates directly with Gmail and Outlook. Its core function allows you to schedule emails to be sent at a later time, ensuring your messages arrive when they are most likely to be read. The tool also includes features like email reminders, message tracking, and a “Respondable” feature that uses AI to optimise your email timing and language for better responses.

Beyond scheduling, Boomerang offers a suite of productivity tools. You can set reminders for emails that haven’t received a reply, pause your inbox to avoid distractions, and even request read receipts. The platform is designed for individuals and small teams who want to take control of their email without switching to a completely new client. Its simplicity and reliability have made it a staple for many professionals.

Key Features of Boomerang for Email Scheduling

Boomerang’s feature set is focused on making email management efficient and predictable. The standout features include:

These features are tightly integrated into Gmail and Outlook, meaning you don’t need to learn a new interface. The scheduling process is intuitive: compose your email, choose a send time, and Boomerang handles the rest. For most users, this is enough to improve email response rates and reduce the stress of an overflowing inbox.

Top Alternatives to Boomerang in 2025

The email productivity market has expanded significantly, with tools catering to different needs from sales outreach to team collaboration. Below is a table of the leading alternatives you will encounter:

Alternative Primary Focus Best For
Mixmax Sales engagement and email tracking Sales teams and outbound communication
Right Inbox Email scheduling and templates Individual professionals and freelancers
HubSpot Sales Hub CRM and sales automation Sales teams with existing HubSpot usage
Gmelius Collaborative email management Teams needing shared inboxes and workflows
Yesware Email tracking and templates Sales professionals and account managers
Mailbutler Productivity and task management Individual users and small teams

Each alternative brings a unique set of strengths, and the best choice depends heavily on your workflow and whether you need sales-focused features or simple scheduling.

Boomerang vs Mixmax: Feature and Pricing Comparison

Mixmax is a powerful sales engagement platform that extends far beyond simple email scheduling. It offers advanced email tracking with real-time notifications when recipients open your email or click links. Mixmax also includes sequence automation, meeting scheduling, and email templates that can be personalised for each recipient. This makes it a strong choice for sales teams who need to manage outreach at scale.

Feature Boomerang Mixmax
Email scheduling Yes Yes
Email tracking Yes (basic) Yes (advanced with click tracking)
Sequences No Yes
Meeting scheduling No Yes
Pricing (individual) £4.99/month £19/month

For an individual user who only needs occasional scheduling, Boomerang is more affordable and simpler. However, if you require detailed analytics and automated follow-ups, Mixmax justifies its higher price with a richer feature set. Teams engaged in outbound sales will find Mixmax’s capabilities transformative, whereas Boomerang remains a solid, no-fuss option for personal productivity.

Boomerang vs Right Inbox: Pros and Cons

Right Inbox is a direct competitor to Boomerang, offering similar scheduling and tracking features with a slightly different approach. One of its key advantages is the ability to create email templates and send later with a single click. Right Inbox also includes a “Don’t Send” feature that allows you to unsend emails within a configurable window, which Boomerang lacks.

On the downside, Right Inbox does not have an AI feature like Respondable to optimise email content. Its tracking is also simpler, providing only open and click data without the depth that sales professionals might need. For users who prioritise scheduling and templates over AI suggestions, Right Inbox presents a clean alternative.

Boomerang’s strength lies in its reminder system and inbox pause, which Right Inbox does not offer. If you frequently need to pause your inbox to focus on deep work, Boomerang has the edge. However, for users who want a lighter tool with template support, Right Inbox is worth considering.

Boomerang vs HubSpot Sales Hub: Best for Teams

HubSpot Sales Hub is a full-fledged CRM with email scheduling as just one component. It is designed for sales teams that need to manage contacts, track deals, and automate email sequences within a single platform. The email scheduling feature is robust, allowing you to set send times based on recipient time zones and track engagement in the CRM.

For a team already using HubSpot, the integration is seamless. Emails logged automatically against contacts, and you can create workflows that trigger follow-ups based on recipient behaviour. Boomerang, by contrast, is a standalone tool that does not offer CRM functionality. It is better suited for individuals or small teams that do not need a full sales system.

HubSpot Sales Hub is significantly more expensive, with plans starting at around £50 per user per month for the full suite. Boomerang’s team plans are far cheaper, but you sacrifice the depth of data and automation that HubSpot provides. For teams scaling their sales operations, HubSpot is the clear winner. For simple scheduling, Boomerang remains more practical.

Boomerang vs Gmelius: Collaboration and Workflow

Gmelius transforms Gmail into a collaborative workspace by adding shared inboxes, board views, and automated workflows. It is designed for teams that need to manage customer support, sales, or project communication from within their email client. Gmelius allows you to assign emails to team members, set statuses, and create automated replies based on triggers.

Boomerang is fundamentally a personal productivity tool, lacking any collaboration features. If your team needs to share an inbox or track email-based tasks, Gmelius is the superior choice. However, Gmelius is more complex to set up and has a steeper learning curve. For a lone professional, Boomerang’s simplicity is more appealing.

Pricing for Gmelius starts at around £10 per user per month for the basic collaboration features, which is competitive for teams. Boomerang’s individual plan is cheaper, but for teams, Gmelius offers better value if you need shared workflows. The decision hinges on whether you need collaboration or personal scheduling.

Boomerang vs Yesware: Email Tracking and Templates

Yesware is a sales-focused tool that excels in email tracking and template management. It provides detailed analytics on open rates, click rates, and attachment views, which is invaluable for sales professionals. Yesware also offers a library of email templates that can be categorised and shared across a team, making consistent outreach easier.

Boomerang offers basic tracking but does not match Yesware’s granularity. Yesware’s templates are more advanced, allowing for dynamic fields and A/B testing of subject lines. However, Yesware is more expensive, starting at £15 per month for the individual plan. For a salesperson who relies on data-driven outreach, Yesware is the better investment.

Where Boomerang wins is in its reminder system and inbox pause. If your primary need is to schedule emails and get reminded about replies, Boomerang is sufficient. But if you live and die by open rates and need to iterate on your email copy, Yesware is the tool to choose.

Boomerang vs Mailbutler: Productivity and Integration

Mailbutler positions itself as a productivity assistant that integrates with Gmail, Outlook, and Apple Mail. Beyond scheduling, it offers task management, note-taking, and contact management directly within your email client. Mailbutler also includes email tracking and template features, making it a more comprehensive productivity hub than Boomerang.

The key advantage of Mailbutler is its cross-platform support. Boomerang works primarily with Gmail and Outlook web, while Mailbutler covers Apple Mail and other clients. For users who prefer native desktop clients, Mailbutler is a better fit. However, Mailbutler’s scheduling is not as seamless as Boomerang’s, and its AI features are limited.

Pricing for Mailbutler is similar to Boomerang, starting at around £5 per month for the basic plan. For users who want to manage tasks and contacts alongside email scheduling, Mailbutler offers more value. But if you only need scheduling and reminders, Boomerang is more streamlined.

Boomerang vs Snov.io: Sales Outreach and Automation

Snov.io is a dedicated sales outreach platform that combines email finding, verification, and drip campaigns. It is not primarily a scheduling tool but rather a full-fledged sales automation platform. Snov.io allows you to build prospect lists, send cold emails in sequences, and track all interactions in a CRM.

Boomerang has no overlap with these capabilities. It is purely an email productivity tool for existing contacts. For sales professionals who need to generate leads and automate cold outreach, Snov.io is essential. Boomerang would be used alongside Snov.io for personal email management, not for sales campaigns.

Snov.io’s pricing starts at £30 per month for the basic plan, which includes email credits. This is significantly more expensive than Boomerang but reflects its specialised nature. If your work involves outbound sales at scale, Snov.io is the tool you need. For day-to-day email management, Boomerang remains a useful companion.

Boomerang vs Streak: CRM and Email Management

Streak is a CRM that lives inside Gmail, allowing you to manage pipelines, track email engagement, and collaborate with team members without leaving your inbox. It offers email scheduling as part of its feature set, but its core strength is pipeline management for deals, hiring, or projects. Streak is ideal for users who need lightweight CRM functionality integrated with email.

Boomerang lacks any CRM features, making Streak the superior choice for users who need to track deals or manage a sales pipeline. Streak’s scheduling is basic compared to Boomerang, but the trade-off is a complete view of your communications within a structured pipeline. For a salesperson managing multiple deals, Streak is more valuable.

Streak’s pricing starts free for basic CRM features, with paid plans from £15 per user per month. Boomerang is cheaper for individual scheduling, but Streak offers more functionality for teams. The choice depends on whether you need pipeline management or just scheduling.

Boomerang vs Google Workspace Built-In Scheduling

Google Workspace now includes built-in email scheduling through the “Schedule send” feature in Gmail. This allows you to choose a delivery time without any third-party tool. For many users, this native feature is sufficient, especially since it is free and requires no setup. Google has also added “nudges” that remind you to follow up on emails.

Boomerang offers more advanced scheduling options, such as recurring send times and automatic reminders for replies. It also includes the inbox pause feature, which Google does not provide. For power users who need granular control, Boomerang adds significant value. But for casual users, Google’s built-in scheduling may be enough.

If you are on a tight budget and only need basic scheduling, Google Workspace’s native tools are the best choice. However, if you rely on reminders, inbox pause, or AI-powered suggestions, Boomerang remains a worthwhile investment. The table below summarises the differences:

Feature Google Workspace Boomerang
Email scheduling Yes (basic) Yes (advanced)
Reminders for replies No Yes
Inbox pause No Yes
AI suggestions No Yes (Respondable)
Cost Free £4.99/month

Pricing Comparison: Boomerang vs Top Alternatives

Pricing is a critical factor when choosing an email tool. The table below compares the starting prices for individual plans across the main alternatives:

Tool Individual Plan (per month) Team Plan (per user per month)
Boomerang £4.99 £14.99
Mixmax £19 £29
Right Inbox £4.99 £9.99
HubSpot Sales Hub £50 £90
Gmelius £10 £15
Yesware £15 £35

Boomerang and Right Inbox are the most affordable individual options, while HubSpot and Mixmax are significantly more expensive. For teams, Right Inbox and Gmelius offer the best value if you need collaboration features. However, the cheapest option is not always the best if you need advanced sales features or CRM integration.

Which Email Scheduling Tool Is Best for Your Needs

Choosing the right tool depends entirely on your workflow and priorities. If you are an individual professional who needs simple scheduling and reminders, Boomerang is an excellent choice at a reasonable price. Its inbox pause and AI features provide additional value without overwhelming complexity.

For sales teams, Mixmax, Yesware, or HubSpot Sales Hub offer the tracking and automation needed to manage outreach effectively. These tools are more expensive but provide a return on investment through improved conversion rates. If you need CRM integration, Streak or HubSpot are the best options, while Gmelius is ideal for collaborative teams.

Finally, if you are on a budget and only need basic scheduling, Google Workspace’s native feature is sufficient. For everyone else, Boomerang remains a strong contender that balances features, price, and ease of use. Evaluate your specific needs for tracking, collaboration, and automation before making a final decision.
