Hey, also wanted to let you know that the e-mail they sent out had errors in it. According to the new pricing page (here: https://www.migadu.com/pricing/) The $9/mo plan offers unlimited domains. Definitely pricier than the previous $5/mo, but much more reasonable than $29/mo for unlimited domains. Hope this helps.

The 5-domain limit on the Micro plan is also a "soft" limit, and support has implied to me that you could negotiate something that works for you if need be.
