I've been using Inboxroad for almost three years now and I would highly recommend to any startup or B2C company. I have nothing negative to mention about Inboxroad email service, they always give the best quality support and always get to the answer questions I have. Inboxroad is a fully managed platform, they can handle your emails with different email providers, such as Gmail, Office 365, etc. Inboxroad lets me build and train my AI and machine learning models. I just recently started using Inboxroad, but I am happy that it's easy to integrate with my Google App Script. I've tested their service and I'm totally content with the email delivery, I just can get my emails delivered straight to my recipients inbox. I like that we can use this service without having to purchase another mail provider because it is part of our email platform. The price has been reasonable so far.The support staff are very friendly. The interface is not as user-friendly as other providers. It is somewhat difficult to navigate through some aspects of the website. We have recently implemented InboxRoad's services into our internal communication tools. It was one less thing for us to worry about.
