WP Mail SMTP – The from Name of Emails Cannot Be Translated

Overview of the Issue

When you use WPML with WP Mail SMTP (opens in a new tab), you cannot translate the From Name of the emails. Emails in secondary languages are sent with the From Name of the default language.

Workaround

Please, make sure of having a full site backup of your site before proceeding.

• Go to WP Mail SMTP → Settings and turn on Force From Name.
• Go to WPML → Settings → Custom XML Configuration and add:

  <wpml-config>
    <admin-texts>
      <key name="wp_mail_smtp">
        <key name="mail">
          <key name="from_name"/>
        </key>
      </key>
    </admin-texts>
  </wpml-config>

• Add this code to your theme’s functions.php file:

  add_filter( 'wp_mail_smtp_options_get', function ( $value, $group, $key ) {
  	if ( 'mail' === $group && 'from_name' === $key && is_string( $value ) ) {
  		$value = apply_filters( 'wpml_translate_single_string', $value, 'admin_texts_wp_mail_smtp', '[wp_mail_smtp][mail]from_name' );
  	}
  	return $value;
  }, 10, 3 );

• Go to WPML → String Translation and translate the From Name.
