Email Address Internationalization (EAI)
- October 27, 2021
- Posted by: Nicola Selenu

A process that enables email addresses with either the domain name or mailbox name in different languages and scripts to work properly when sending and receiving emails. These may include email addresses represented in Arabic, Chinese, Cyrillic, Hebrew, Japanese or Tamil scripts. For instance, if an individual tried to email another person using an email address ending in .онлайн (.online), but the recipient’s email box is not EAI-ready, their message would never be received and they would not be able to communicate with each other.
