Very bad cold email outreach tool
As a cold email outreach tool, it's a very raw product. Mailings are sent without issue, but there is no data on replies or bounces. Most importantly, replies are not displayed in the service's inbox. Even worse, many emails with the status "email opened" are actually bounces. Support is slow and unhelpful. They answer with general phrases, and their AI bot is more helpful. I asked for a refund and have not received a response yet. Not recommended.

Hi Alex We are extremely sorry for the frustration you had with our product. You were one of our earliest customers while the product was still in its early, bootstrapped stage. At the time, key features like reply tracking and bounce detection weren’t where they needed to be, and we take full responsibility for that. Since your review, we've made significant improvements: • Inbox syncing is far more reliable • Bounce detection accuracy has been overhauled • Support responsiveness is night and day better We also want to confirm that your refund was processed at the time of your original request. If you’re open to it, we’d genuinely appreciate the chance to offer you a free trial for a much better experience today.
