Email address is empty. I want to get guest user email address in custom observer file .

Answer 1

You can get guest customer email by using following

$shippingAddress = $quote->getShippingAddress();

$logger->info($shippingAddress->getEmail());

Hope this solution works for you

Answer 2

instead of

$logger->info($address->getEmail());

use this line

$logger->info($order->getCustomerEmail());
