Boomerang Features

Boomerang features many tools that can help businesses and organizations of all sizes and industries help improve operations, including:


Powered by artificial intelligence, Respondable is a feature that ensures your emails are accurate and readable by your audience. As you type your message, you’ll see a pop-up window next to your email that determines the chances of you receiving a response from the recipient. It takes into consideration subject length, question count, word count and reading level. Other advanced features, which can be found in the Pro version, also identify the level of positivity, politeness and subjectivity. 

Inbox Pause

If you’re receiving large amounts of new email, then you have the option to stop them from coming in. This is to avoid unnecessary stress and eliminates interruptions when you’re working on important projects. This doesn’t mean you won’t be receiving emails forever as you get to dictate how long you’ll keep your inbox on pause. 


Like any other email platform, Boomerang offers reminder features. This is to ensure you won’t miss out on any important notifications. You could be in the middle of a current project when a new one comes in. To make sure you don’t forget about it, you can use this feature to bring this email back to you on a specific time. If you’re not sure why you set a reminder in the first place, you can attach notes to provide a context. 

Recurring emails 

If there’s a recipient you send multiple emails to on a weekly or even daily basis, then the recurring email feature is helpful in staying on top of your messages. With this feature, you don’t have to manually send out the same emails each time. This saves more time and keeps your emails consistent.  

Follow-up emails

If you don’t immediately get a response, then it’s best to follow up on your recipients. However, it can be a hassle to keep track of these people. With Boomerang, you can set a schedule for the application to send a message if there’s no reply within a few hours or days. This keeps you updated and ensures your recipients haven’t been forgotten. 

Boomerang Benefits

There are many benefits for businesses using Boomerang, including:

Instead, you can focus on working on your projects and let the application do the work for you. Proofreading your messages doesn’t need to take longer since you have the Respondable feature to assist you. Additionally, when sending out recurring emails, all you need to do is set up a time and then Boomerang sends them out for you.
