Support is Very Responsive and Insightful Understanding the black box / machine learning of email reputation is extremely tricky. As an eager company wanting to build outbound it's easy to fall into traps that ultimately cause spam issues to constrain your goals. Warmup Inbox was the guidance we needed to understand best practices - they have always been super supportive and quick to respond which is ideal when there is a lot of uncertainty in the email rep space. 5 stars no questions

Warmed up quick and easy Great service that was easy to use. The only hiccups I had were issues in the configuration of my own code base. Worked quick and seemless to get my private inboxes and mail domain trusted by most major email providers. When I messaged to cancel, the process was very quick, and I was even offered by the rep a refund for my charge 24 hours before since I would not be using the service. Thanks Lucia! No bad things to say only good!

Don't use Warmup Inbox After I used Warmup Inbox for a month, more and more e-mails were blocked. Eventually, Microsoft blocked my email account on all their servers due to the messages of Warmup Inbox.
