it's very easy to set up, you can do this by yourself in less than 30 mins! I have never had any problem with EasyDmarc, everything works fine as expected every time. It takes some time to set up but once done it does its magic! The only thing that could be improved would be the UI/UX of the application. The layout should look more modern and intuitive. We are now able to solve our SPF issues without using another tool or service, we just need to setup an A record pointing to our IP address and let EasyDmarc take care of everything else.
