What is Respondable?
Boomerang Respondable is an AI-powered email assistant that helps you write more effective, actionable emails in real-time. Built directly into Gmail and Outlook's compose window, it analyzes your writing as you type and provides instant feedback on factors that impact response rates. The tool uses machine learning algorithms trained on hundreds of millions of messages to predict the likelihood that your email will receive a response.
Key features include real-time analysis of subject length, word count (optimal range: 50-125 words), question count (1-3 questions recommended), reading level, sentiment, politeness, and subjectivity. Respondable scores your message and provides customized advice when factors receive poor rankings, helping you strike the right tone without interfering with your creativity. Advanced features like sentiment analysis, politeness measurements, and subjectivity tracking are available for Pro and Premium users.
Respondable is designed for anyone who wants to improve their email communication effectiveness - from professionals emailing their bosses, to job seekers reaching out for information, to salespeople crafting outreach emails to clients, potential hires, or business partners. It's trusted by millions of Boomerang users and works across all email addresses on both Gmail/Google Apps and Microsoft Office365/Outlook.com platforms, though it's only available on desktop.
The tool teaches you how to improve your writing through actionable advice delivered in real-time, giving you unique insight into your own writing style and how it impacts response rates. Rather than auto-rescribing or putting words in your mouth, Respondable augments human capabilities by curating suggestions that help you compose the optimal email message while maintaining your personal voice.

Frequently asked questions about Respondable
What is Respondable and how does it work?
Respondable is an AI assistant that uses artificial intelligence and machine learning to help you write better, more actionable emails in real-time. As you write emails in Gmail or Outlook's compose window, algorithms predict the likelihood that your message will receive a response and explain this analysis in an easy-to-understand way. The tool is trained on data from millions of messages and tens of millions of data points to identify factors that contribute to email response probability.
What factors does Respondable analyze in my emails?
Respondable analyzes subject length, word count, question count, reading level, sentiment, politeness, and subjectivity. The optimal email length is 50-125 words (responded to 50% of the time), and 1-3 questions per email is recommended. It also evaluates tone balance, including positivity, politeness, and whether your email is too subjective or objective.
Is Respondable free to use?
Yes, Respondable is free to use with the Basic plan. All existing Boomerang users receive Respondable immediately, and new users get it when they install Boomerang. Access to Respondable for unlimited messages is included in the free Basic plan for both Gmail and Outlook platforms. However, advanced features require a Pro or Premium subscription.
What advanced features require a paid subscription?
Advanced features including sentiment analysis, politeness measurements, subjectivity tracking, and personalized analysis of your writing style are only available for users on Boomerang for Gmail's Pro and Premium plans. These advanced parameters start at $15 per user per month and provide deeper insights into your email communication effectiveness.
Which email platforms does Respondable support?
Respondable works as a plugin for both Gmail (including Google Apps) and Outlook (including Microsoft Office365 and Outlook.com). You can install the plugin for both platforms and it will work across all of your email addresses. However, Respondable is only available on desktop browsers, not on mobile devices.
How does Respondable differ from an auto-responder?
Respondable is not a quick auto-responder that puts words in your mouth or automatically writes emails for you. Instead, it provides real-time suggestions for how to improve your writing without interfering with your creativity. It scores your message and offers customized advice when factors receive poor rankings, working in tandem with you to compose the optimal email while maintaining your personal voice and creativity.
What tone recommendations does Respondable provide?
Respondable helps you strike the right balance of politeness, positivity, and subjectivity. Moderately negative emails receive a 13% uplift in response rate compared to neutral emails, while happy emails elicit a 15% uplift. The tool helps you find the perfect tone balance and provides specific advice when emailing your boss, requesting information, or crafting outreach emails to clients, potential hires, or business partners.
Do I need to be an existing Boomerang user to use Respondable?
No, you don't need to be an existing Boomerang user. New users will receive Respondable immediately upon installing Boomerang for Gmail or Boomerang for Outlook. The feature is included as part of both platforms and is immediately available for all users, whether they're new or existing Boomerang users. Simply reload your Gmail or Outlook window after installation and the new features will appear.
How accurate are Respondable's response predictions?
Respondable's algorithms are trained on hundreds of millions of data points from public and proprietary (aggregated and anonymized) email datasets, making its predictions highly accurate. The tool has determined a broad set of factors that contribute to an email's probability of garnering a response using several machine learning techniques. Short emails between 50-125 words are responded to 50% of the time, which is one of the key insights validated by their data.
Can Respondable help me write emails for specific situations?
Yes, Respondable provides specific guidance for different email situations. It helps you strike the right tone when emailing your boss, increase your chance of receiving responses when emailing for information you need, and craft perfect outreach emails to new clients, potential hires, or business partners. The real-time analysis and customized advice adapt to your specific communication context and goals.
