Email AI that Does More Than Just Grade Your Writing **Rating:** 5.0/5.0 stars **Reviewed by:** Matthew P. | Instructor, Small-Business (50 or fewer emp.) **Reviewed Date:** April 27, 2023 **What do you like best about Opnbx.ai?** Opnbx.ai has been an incredible asset since I began using it nearly a month ago. My strategy has gone from shooting in the dark half the time to be able to interact personally with every prospect I'm reaching out to. I'm a math person, so I'll break down exactly how much time Opnbx is saving me writing personalized emails: Amount of emails per week I send on average - 175 At 7-10 minutes of personalization per email, that would typically take up to 29 HOURS. Opnbx brings that down to 2-4 minutes or only up to 11.5 HOURS a week. Opnbx should be a no-brainer addition to your tech stack at its price point. **What do you dislike about Opnbx.ai?** There is truly nothing negative to say. Opnbx is a young platform that is continuously evolving. If you have an issue, their team fixes it exceptionally quickly. **What problems is Opnbx.ai solving and how is that benefiting you?** The amount of time it takes to write highly personalized emails on a day to day basis. ### 2.
