International Characters in Mailchimp

Websites and email clients use certain character sets to interpret international symbols, like ñ and é. Mailchimp supports 3 character sets in emails and audiences: Unicode (UTF-8), ASCII, and extended ASCII.

• Mailchimp relies largely on UTF-8. We don’t recommend using non-ASCII characters that aren't UTF-8 encoded, because this could cause errors in your email layout.

• We encourage you to research how to use character encoding with your preferred word processor or spreadsheet applications. When your documents are set to UTF-8, Mailchimp will correctly render your inserted or uploaded content.

• Mailchimp can’t process UTF-8 characters in the prefix of your contacts’ email addresses, but it’s okay to use UTF-8 characters in the domain name. For example, we'll block direcciónelectrónica@domain.com because the international characters are in the prefix, but we'll allow an address like test@ñoñó1234.com, because the characters are in the domain name.
