Get Ready for Email Address Internationalization in Summer ’20

Starting in Summer ’20, Salesforce will support Email Address Internationalization (EAI) through UTF-8 encoding so that you can use non-Latin-based language characters in email addresses. We’re prepping all standard email fields for the switch and sharing steps that you can take so that your custom email fields are ready. You don’t have to use international email addresses after the switch, but if you do, preparing your Salesforce org ensures a smooth transition.
Where: This change applies to Lightning Experience, Salesforce Classic, and all versions of the Salesforce app in all editions.


EAI support isn’t generally available unless, or until, Salesforce announces its general availability in documentation or in press releases or public statements. We can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

How: If you want to use internationalized emails, there are four parts to preparing for Email Address Internationalization (EAI) support.
  • Ensure that UTF-8 support exists throughout the email’s path.
  • Update your integrations to support Unicode characters.
  • Adopt the latest Apex and API version.
  • Ensure that all fields storing email addresses use the email data type.
