What is Respondable | Boomerang for Gmail?
Respondable is an email assistant built into Boomerang for Gmail that scores drafts as you type. It predicts how likely a message is to get a reply and explains which factors drive that score, drawing on patterns from millions of sent emails. The tool surfaces tips on tone, including politeness, positivity, and subjectivity, so you can adjust wording before hitting send.
Most Gmail users guess at tone and hope for a response. Respondable gives live feedback inside the compose window instead of waiting for silence. That makes it especially useful for outreach to clients, follow-ups with your manager, and any thread where a missed reply costs time.
Sales reps, recruiters, and anyone living in Gmail who needs higher reply rates are the core audience. Respondable ships as part of the Boomerang extension, which also covers send-later, reminders, and inbox pause. Boomerang reports more than 1 million businesses on the platform and SOC 2 Type 2 certification on its main site.
