No it’s certainly $999/yr. and $349 for a 3 character email. And $99 after that.
Interesting, don't see that listed on https://hey.com/pricing/. Where are those policies listed?
If you select a 2 or 3 character email name when signing up, it pitches the up charge to you. Not a big deal to select longer, and personally if I use it I’ll be using my own domain name.
