About

KDMARC is an email authentication and anti-spoofing solution that helps organizations in securing their outbound mail flow. KDMARC's Dynamic SPF feature allows the whitelisting and blacklisting of domains and IPs in a single click on the KDMARC dashboard. Dynamic DMARC allows the change in policy (None, Quarantine and Reject) at real time. The tool is aimed at helping customers take relevant security actions in a timely manner to ensure more robust email security. KDMARC allows organizations to trust their mailbox by ensuring prevention of brand abuse, increasing email deliverability, prohibiting malware & ransomware attacks thus, boosting email engagement rate.

About

SuperMailOS is managed business email on your own domain for small teams. You bring your domain; SuperMailOS runs the mail server and handles deliverability — SPF, DKIM, DMARC, IP reputation, and warmup — so your email lands in the inbox, not the spam folder. Setup takes minutes: verify your domain with one-click DNS on Cloudflare, DigitalOcean, and other providers (or guided copy-paste on any registrar), invite your team, and start sending. Every person gets a real mailbox; aliases like hello@ and support@ are unlimited and free. Webmail is as simple as Gmail — threads, instant search, keyboard shortcuts, labels, dark mode — plus IMAP and SMTP for any mail app, and a live deliverability dashboard showing your mail landing. Flat pricing per mailbox: Pro $3/mailbox/month annually (10 GB, 3 domains), Business $5 (30 GB, unlimited domains), custom at 50+. 14-day free trial, no credit card.

Pros & Cons from Real Users

Pros

  • The tool helps us stop fraudulent emails that fail DMARC authentication from getting delivered to the recipients’ inbox.
  • I like how we can easily configure our domain’s DMARC and SPF records with the help of this tool to authenticate legitimate emails and ensure a healthy outbound email flow.
  • I love how simple and effective the tool is. It has made it very easy for us to manage the outbound emails flowing from all our domains.
  • I have been using this tool for more than a year now and it has helped me a lot in securing my domain against misuse. It has helped us in a major way in terms of our email deliverability rate. Smart SPF is one of the best features that this product offers. It helps you alter IPs and email sources in the SPF record through its dashboard without the need to visit the DNS.
  • As the company grows, the threats posed to its reputation also grow. Domain forgery is one of the leading threats that a company faces. People can destroy your market reach using your domain name to send inappropriate emails or malicious content to your customers. However, a tool like KDMARC comes in handy while dealing with this situation. It has amazing features like Smart SPF and Identity Access Management (IAM) that make domain security a very easy game.

Cons

  • There is nothing that I dislike about the tool. Great tool to protect our email domains.
  • I don’t dislike anything about this tool. In fact, it offers quite interesting features and a user-friendly dashboard.
  • I have enjoyed using the tool. So far, no complaints.
  • Improvement is always an ongoing process but I don’t think that there’s any scope for an immediate change in this product or its design.
  • KDMARC has to be one of the most user-friendly domain security tools in the market. Can’t find anything wrong with this product.
