# Set Up Email Address Internationalization (EAI)

Email Address Internationalization (EAI) allows non-Latin-based characters in email addresses when sending emails to and from Salesforce. You can choose whether emails containing a mix of American Standard Code for Information Interchange (ASCII) and international email addresses are sent as separate or single emails.

Before enabling EAI, review the considerations and prepare your Salesforce org for the feature.

![Note](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-sales-sales_productivity-264-0-0-production-enus/b2f6c36a-fa61-4a3c-9752-032ce1818a69/images/icon_note.png)

Note Orgs created in Summer ’20 or later have EAI enabled by default.

1. From Setup, in the Quick Find box, enter Email Address Internationalization, and then select **Email Address Internationalization**.
2. Select **Allow international email addresses**.
3. Select your Mixed Recipient Addresses setting.
    
    - **Split**—Emails sent from Salesforce containing ASCII and EAI email addresses in the TO, CC, and BCC fields are split into two email messages. Delivery to the ASCII email address recipients succeeds. International emails are delivered successfully as long as the recipient’s Email Service Provider (ESP) and Mail Transfer Agent (MTA) support EAI. This setting is the default.
        
        ![Important](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-sales-sales_productivity-264-0-0-production-enus/b2f6c36a-fa61-4a3c-9752-032ce1818a69/images/icon_important.png)
        
        Important If you choose to send email from Salesforce using an EAI email address, selecting this option has no effect. A single email is sent because of the EAI email address in the from field.
    - **Allow**—Emails sent from Salesforce containing ASCII and EAI email addresses in the TO, CC, and BCC fields are sent as a single email. Delivery is only successful for recipients whose mail servers support internationalized emails.

4. Save your changes.
