I've eventually settled on using fastmail and their masked email feature which can create addresses on my own domain for this. I love DDG and appreciate anyone helping in this space to make email more manageable but I assume these addresses will be quickly blocked from many services just like the firefox relay addresses are.
I wish there was a way for these relay services to be effective since they are much, much easier to get someone to use than telling them to just up and move from gmail to fastmail.
