  if ($coupon_result->fields['coupon_is_valid_for_sales']) {
    $message .= TEXT_COUPON_IS_VALID_FOR_SALES . "\n\n";
  } else {
    $message .= TEXT_NO_COUPON_IS_VALID_FOR_SALES . "\n\n";
  }
  if ($coupon_result->fields['coupon_product_count']) {
    $message .= TEXT_COUPON_PRODUCT_COUNT_PER_QUANTY . "\n\n";
  } else {
    $message .= TEXT_COUPON_PRODUCT_COUNT_PER_ORDER . "\n\n";
  }

TEXT_COUPON_IS_VALID_FOR_SALES and TEXT_NO_COUPON_IS_VALID_FOR_SALES should be TEXT_COUPON_IS_VALID_FOR_SALES_EMAIL, and TEXT_NO_COUPON_IS_VALID_FOR_SALES_EMAIL.

TEXT_COUPON_PRODUCT_COUNT_PER_QUANTY isn't defined, might be TEXT_COUPON_PRODUCT_COUNT_PER_PRODUCT.

Any first-timers want to build a PR?

Hi,
I’m a computer graphic designer, just try to learn php and have never used GitHub(PR means Pull request, right?)
Anyway I will try my best.

Fantastic! Thanks for your help.
