Do you want to create email with an international domain or a pretty emoji domain? We will tell you how easy it is to do with Fake Email Generator.
Create a punycode of the desired domain using Punycode Converter
We are looking for a domain xn--8j8h that is available for registration in any domain registrar (each registrar may have different restrictions, so read the rules of your registrar.) and register it.
Now you have to add MX settings so your domain starts working with Fake Email Generator.
Note: Some older devices may not understand the emoji and IDN domains, if you convert email address into a punycode and such devices will recognize it.
