Can you confirm that the Order Status is “Complete” for the gift cards purchased? You should see the Gift Card number along with the recipient email in the Order line items inside the admin area.
If the order is Complete and it shows the Gift Card number, the emails are attempting to be sent using your email system. To independently verify this, you can log all outgoing emails using this free plugin:
https://wordpress.org/plugins/email-log/
After installing the plugin, perform another test order. After the order is Complete and the gift card number has been generated, check the email log to see which emails were sent. You should see several, to the site admin and to the customer.
Also, check the Junk Mail folder for the recipient email address. If the gift card is not there, the email may have been sent but been outright rejected by the recipient’s email server (not even going to the Junk Mail folder).
Most email servers are very strict when it comes to attempting to prevent spam and may see the Gift Card email as possibly junk mail. As a result, most WooCommerce installations are not trusted by default, since anyone could send out spam from their server.
To combat this, we recommend using a more reliable email server for sending emails. Contact your website host first to see if they offer something with your plan. Most will have a trusted SMTP server that you can use.
Another option that you can setup yourself is Pepipost (https://pepipost.com) to handle your email delivery. There is no cost (until you send more than 3,000 emails in a single month and even then, it’s pretty inexpensive for the service you get). They will ensure that your emails are delivered and you can even track open rate to know for sure that someone received their email and opened it.
Amazon’s Simple Email Service (SES) is also another viable option, although it is more difficult to get set up initially. You can learn more about it here: https://aws.amazon.com/ses/
Both Pepipost and Amazon SES integrate into WordPress easily with the WP Mail SMTP plugin (also free): https://wordpress.org/plugins/wp-mail-smtp/

To quickly test the gift card emails, click on Pimwick Plugins -> PW Gift Cards -> Designer -> Send Preview Email. If you get the gift card, try different email accounts (such as @gmail.com, @yahoo.com, etc) to verify that everything is working.
