Review on ProDMARC by Dragan Nelson

I like that you can block domains from sending emails if they are not compliant with SPF records or DKIM keys which it does automatically for many services (if enabled).

You have options when creating rules but sometimes there's no clear option - just "Use this rule" without any explanation! This could be improved by adding more explanations about what each setting means so users don't need an expert knowledge background before using them properly. The biggest benefit we've seen since implementing has been reducing our bounce rate drastically compared to other providers who were charging us $20-30 per month extra than prodmarmc was offering at around half price!!
