Does what it says Warmup Inbox is a pretty easy and intuitive to use warmup tool. They do what they promise, i.e warmup your emails. I like the credit system, you can buy X amount worth of credits and use them to pause and resume new inboxes as and when you feel the need. Lucia and Camilo are great at what they do, support has been good and empathetic.

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.

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
