"Stable, Easy-to-Use OnDMARC with Outstanding Specialist Support"

5/5

What do you like best about Red Sift OnDMARC?

We have been using OnDMARC for about five years, and it is the only solution we use from Red Sift. The application runs stably and is easy to use. We especially appreciate the support, and the assigned specialist is responsive and helpful with configuration and reporting questions. Review collected by and hosted on G2.com.

What do you dislike about Red Sift OnDMARC?

Sometimes the interface changes unexpectedly, and some of those updates aren’t very convenient for day-to-day work. It would really help to get advance notice before changes roll out, along with a clearer explanation of what is planned to be modified and why. Review collected by and hosted on G2.com.

What problems is Red Sift OnDMARC solving and how is that benefiting you?

OnDMARC provides email security and protection against spoofing of our domains. It also acts as a central database for our domains, which makes it easier to keep track of them and manage everything in one place. We also use the Dynamic SPF feature in OnDMARC (SPF flattening), which helps us manage our SPF setup more effectively. Review collected by and hosted on G2.com.

Response from Natalie Hays of Red Sift OnDMARC

Thank you so much for your review and feedback! I'm glad our team is taking good care of you. I'm also going to pass along your feedback on UI/PX notice to our engineering team to see what we can do in the future to clearly explain changes and movements around the platform.
