.email TLD is around $25/year, which seems too expensive when .com is less than a half, but it would make it easier to explain why there is no website behind my domain (as I just want something for email).
But there’s also more expensive options, so I am curious what you’re paying.
Porkbun 10$ for a year iirc for my .com
I moved there from Namecheap who wanted almost $17 for my domain, and didn’t provide API services
Just be aware that porkbun is one of the ones that has started identity verification. It started with some smaller regions, but they have moved to doing it on most of their regions from what I saw.
