OnDMARC is straightforward to set up and begin using. Its standard features are more comprehensive than those offered by other solutions. For us, the main deciding factor was that dynamic SPF record services are included by default. Previously, we frequently encountered the issue of reaching the maximum limit of 10 SPF records, but with OnDMARC, this is no longer a concern. With support from Redsift, we were able to implement DMARC correctly and have been using it successfully for years. I also appreciate the various options available for investigating and troubleshooting, especially when something like a DNS misconfiguration arises. Review collected by and hosted on G2.com.
The main issue I have encountered is that our IT department is not always aware that we use OnDMARC. This sometimes results in colleagues making DNS changes without consulting anyone or discussing the implications, which means OnDMARC can be overlooked. For instance, a colleague recently modified the MX records on a domain where we use MTA-STS, but the changes were not reflected in OnDMARC. As a result, a small number of external contacts were unable to send us emails for more than a day. It's important to ensure that everyone understands the potential impact when implementing OnDMARC.
