Only just starting but pleased so far
I'm just starting my DMARCReport journey, but I must say I'm very happy so far. You need to be prepared to learn a bit about email security to maximise the benefits of this tool. I had some knowledge, but I'm continually learning.
Email DMARC is a valuable tool that helps ensure email deliverability through reporting, but it requires some effort to implement. DMARCReprort helps to understand problems and identify ways of fixing them. Immediately, I found that my Google SPF record was possibly causing problems; I've since corrected it through research and understanding. I wouldn't have done this without DMARCReporting finding the issue.
I have reached out to DMARCReport support now three times, and they get back to me quickly. I have solved a couple of setup problems with their assistance.
I note someone mentioned the UI, and I agree, it could be a little more intuitive. But to be honest, this is a tool and just as you wouldn't expect to be able to operate a Lathe without some instruction, I think the same applies here.
If you are sending mailshots or your email deliverability is essential for other reasons, then you should consider DMARCReport. However, every business should prioritise email security and phishing detection; this is where DMARCReport will be most beneficial.
It is also fantastic value through AppSumo.
