We had deliverabliy problems with our emails and the tool showed that our email domain records were not setup properly. We fixed the problem and our reputation was improved almost overnight.
A good tool for warming up the mailbox. With the help of it, I discovered that I have problems with delivering letters to our customers. In the dashboard, you can see the reputation score for various mail providers - a great thing. I have only recently started using Warmup Inbox, and have not yet solved the problems with my mailbox, but according to dashboard, we are slowly but surely moving toward success :)
I also want to mention the customer support team, especially Lucia, who promptly and intelligibly answered all my questions and helped with their solution!
