I understand why there are a lot questions about this product and this is (apparently) the first review. The product suffers badly because it lacks a clear tutorial - and that is reflected in the questions. I have an advantage because I'm an experienced user of many email tools. I'd hate to be a newbie trying to work this one out.

First, you will need an email tool that sends cold email in order to to work with Mailyser. I used Mailshake for my own testing (which worked fine) but you could use any cold email tool you want - it doesn't matter - just be aware that you will need such a tool to make this work.

I found the interface to be simple to navigate. For the benefit of inexperienced users, I think that a one-time guide on first login might be helpful. As already mentioned, the tool DEFINATELY needs a proper video tutorial.

Users need to be aware that this is not a tool where you'll have a result in a few minutes. To do a proper analysis of your email will take hours or even days, if you want to run comparisons (which is a key feature of the product). It NEEDS that amount of time to do a proper analysis - but new users need to be made aware of that and provided with an explanation. The features supporting the analysis seem solid and information provided is excellent.

Users should be made aware that this should only be used with properly warmed email accounts. I think that a detailed explanation about that would be helpful for newbies to email marketing. I note that email warming is on their roadmap, which would lift this tool into the realm of truly awesome.

Most email products that i test end up being refunded. I'll be keeping this as a T3 product. The product shows strong potential and really looks like a gem in the making. Highly recommended for email marketers who are interested in better deliverability and inbox placement. Excellent value for money.
