You're right that generic .xyz domains have a history of spam, because they are cheap. However, single-letter premium domains (like w.xyz) operate under entirely different security scrutiny and reputation management. The domain isn't the whole product, but for our target niche, a short, memorable handle is a highly valued status asset. We already have 30+ organic people on our waitlist who reserved their handles. As for the infrastructure, Mailgun is only being used for a working prototype. Using their webhooks was simply the fastest way to validate the core mechanics. Now that the prototype is working, this is the reason I'm looking for a founding engineer to take over this functional proof-of-concept and help migrate us to a custom, cost-effective, and fully controlled email stack from the ground up.
