I've used Migadu for a year now with a paid plan, and I kept having to debug deliverability and DMARC problems.
They ended up changing their setup instructions, but didn't send out an email about it - when I updated everything, things still didn't work, their support answer was something like "welll you deleted your default DMARC selector [according to our instructions], here I fixed it for you duh". As the author says, their new pricing is "competitive", so I need to switch to a larger provider in the next couple of days with similar pricing.
Just offering my 2ยข in case someone else doesn't want to deal with DMARC issues all year either.
