Hi Vladimir, thank you for the reply.
I’ve tested on my site a few times, the sender email address and the From name were taken from my WooCommerce settings correctly: https://nimb.ws/Dm1OVGu
Also, our plugin doesn’t have option for Custom sender. Does it only happen to the Gift Card email but not the other WooCommerce emails?
Perhaps it’s a compatibility issue with another plugin. Have you tested for conflict yet?
If not, I would recommend running a full conflict test as described here:?https://docs.woocommerce.com/document/woocommerce-self-service-guide/
It’s very possible that another plugin (or possibly even your theme) caused a conflict with our plugin, and this will help you identify it.
