Simple and Effective
This tool takes all the frustration and (most of the) black art out of managing all the (dare I say) boring aspects of managing a domain for emailing, ensuring deliverability and preventing scammers from hijacking your domain.
I have always ensured that we have DMARC, DKIM and SPF set up for our domains and I've spent way too much time on sites such as mxtoolbox using the free tool because I'm too cheap to pay them $99 a month. Now though I can actually monitor what is going on with our emails as well.
If you run email marketing campaigns or any kind of business really then you need KDMARC. If you don't know why then buy it and spend the 60 day refund period finding out a)why you need it and b)how expensive their competition is.
Thanks for coming to Appsumo and taking some of the pain out of email.
